When powered by AC mains power supply: Make sure that theAC power supply is 100-240VAC, 50/60Hz. Use the power cord prepared by the manufacturer. Insert one end of it to the power port of the monitor and the other end to the grounded three-pin power jack. To eliminate potential differences, the monitor has a separate connection to the equipotential grounding system. If necessary, connect one end of the provided ground cable to equipotential grounding port on the rear of the monitor, and connect the other end to one point of the equipotential grounding system. Caution: ensure that the monitor is grounded correctly. Attention After the supply mains has been interrupted when power switch remains in the “on” position and is restored after a period of time that is longer than 30 seconds, the monitor will run by the last settings when restarting the monitor. 2. When powered by built-in battery The provided battery of the monitor must be recharged after transportation or storage. If the monitor is switched on without being connected to the AC power socket, it may not operate if there is insufficient battery power. The internal battery will fully charge after 3 hours when the monitor is off and 7-8 hours when the monitor is being used. 3. When powered by 12V DC Vehicle Cigarette Lighter Socket using the official 12VDC Vehicle Power Cable The provided Vehicle Power Cable will power the monitor and recharge the monitor at a rate which is approximately 3 x slower than the Mains Power Supply. It is recommended that the Battery be fully charged to start if being used with the Vehicle Power Cable. If the monitor is switched on without being connected to the Vehicle Power Socket , it may not operate if the internal battery has insufficient battery power. Using the Vehicle Power Cable, The internal battery will fully charge after approx.9 hours when the monitor is off and 16-18 hours when the monitor is being used. 3.2.3 Switching ON the Monitor The system performs self-detection and enters the set default display after switching on the monitor, and the yellow alarm indicator blinks to inform that the user can begin operating it. Checkalltheapplicablefunctionstomakesurethatthemonitorworksnormally. If the built-in battery is to be solely used please fully recharge it before and after using the monitor to ensure sufficient battery power storage. It will take minimal 7-8 hours to charge battery from depletion to 90% charge using the AC Mains adapter. Do not use the monitor to monitor the patient if there are indications of damage or reminders of error. Please contact the local dealer or our company. Start the monitor again 1 minute after it is switched off. 9 3.3 Connection 3.3.1 ECG Connection – This is an optional fitment ECG measurement is to collect ECG data via the ECG electrodes. Electrode connects the patient and the lead cable. The lead cable connects to the monitor. The locations of the electrodes are very important for obtaining correct and clean ECG signals. 1. 2. 3. 4. Connect the lead cable to the right-panel connector marked with the ECG icon. Select electrodes to be used. Use only one type of electrode on the same patient to avoid diversity of electrode impedance. For ECG monitoring, it is strongly recommended to use silver / silver-chloride electrodes. When dissimilar metals are used for different electrodes, the electrodes may be subject to cause large offset potentials due to polarization. Using dissimilar metals may also increase recovery time after defibrillation. Prepare the electrode sites according to the electrode manufacturer’s instructions. Skin clean Clean and dry-abrade skin to ensure low sensor impedance. Mild soap and water is recommended asaskincleanser. Alcohol is not recommended as a skin cleanser; it leaves a film layer that may cause high sensor impedance.If alcoholisused,ensure 30-second dry time. Dry-abrading the skin gently with a dry wash cloth, gauze, or skin preparation product is helpful to remove thenon-conductiveskinlayer. The symbol indicates that the cable and accessories are designed to have special protection against electric shocks, and is defibrillator proof. The locations of the electrode are in the following Figure: Figure 3.5 Electrode Location Note: If skin rash or other unusual symptoms develop, remove electrodes from patient. After starting the monitor, if the electrodes become loose or disconnected during monitoring, The system will display “LEAD OFF” on the screen to alarm the operator. Use either 3 wires or 5 wires of lead cable as required to give the required ECG wave. 3 or 5 Lead is user selected in the ECG Setup Menu 10 5. The name of ECG electrodes and their corresponding locations are as follows Symbol Position RA The intersection between the centreline of the right clavicle and Rib 2 LA The intersection between the centreline of the left clavicle and Rib 2 LL Left part of the upper abdomen RL Right part of the upper abdomen C1 (V1) C (V) C2 (V2) C3 (V3) Chest C4 (V4) electrode C5 (V5) If the electrodes are placed in different places, the lead forms will display differently. C6 (V6) Safety Instructions for ECG Monitoring This Monitor can only be used with ECG lead cable provided by Creative Medical; using ECG lead cable supplied by other companies may cause improper performance or poor protection while using defibrillator. Electric parts of electrodes, leads and cable must not contact any other conductive parts (including ground). This Monitor is resistant against defibrillator and electrosurgical unit use. However readings may be inaccurate for a short time after or during use of defibrillator or electrosurgical unit. Transients may caused by cable circuitry connection blocks while monitoring may be similar to the real heartbeat waveform, and as a result resistance / heart rate alarm may sound. Proper electrode and cable placement according to this manual’s instructions and the instructions for using the electrode will minimise the chance of this transient occurring. IF THE PATIENT IS FITTED WITH A PACE MAKER: This device has been designed to provide inhibition to pacemaker pulse signal, generally the pacemaker pulse is not counted in heart rate measurement and calculation, but when the width of pacemaker pulse is over 2ms, it may be counted. In order to reduce this possibility, observe the ECG waveforms on the screen carefully and do NOT rely entirely on the heart rate display and alarm system of this monitor when monitoring this kind of patient. Keep Pacemaker Patients under extra close surveillance. The improper connection of an electrosurgical unit may cause burns, the monitor may be damaged or cause deviations of measurement. You can take some steps to avoid this situation, such as do NOT use small ECG electrodes, choosing the position which is as far away as possible from the estimated Hertzian waves route, using larger electrosurgical return electrodes and connecting with the patient properly. No predictable hazard will be caused by the summation of leakage currents when several items of monitor are interconnected. ECG lead cable may be damaged while using defibrillator. If the lead cable is used again, please do the functional check first. When the monitor is inoperable due to an overload or saturation of any part of the ECG amplifier, it will prompt, “Lead off” to alert the operator. 11 3.3.2 Blood Pressure Cuff Connection 6. Connect the air hose to the right-panel connector marked with the NIBP icon. 7. Remove packaging and wrap the cuff around patient’s upper arm. Requirements of the cuff: 1) Appropriate cuff should be selected according to the age of the subject. Its width should be 2/3 of the length of the upper arm. The cuff inflation part should be long enough to permit wrapping 50-80% of the limb concerned. See the table below for the dimensions: Note: The size of the cuff selected should suit the subjects while measuring. This is only a general guide. 2) 3) 4) 5) 6) Cuff Model Limb Circumference Cuff Width Neonate Cuff 6.0cm~9.5cm 3cm Small-sized Paediatric Cuff 6cm~11cm 4.5cm Middle-sized Paediatric Cuff 10cm~19cm 8cm Large-sized Paediatric Cuff 18cm~26cm 10.6cm Adult Cuff 25cm~35cm 14cm Extra Large Adult Cuff 35.0 ~ 46.0cm 18cm Thigh Cuff 45.0 ~ 56.5cm 25cm Remove packaging prior to fitting on the cuff, and wrap the Cuff around the upper arm evenly to appropriate tightness. Remember to empty the residual air in the cuff before the measurement is commenced. Locate the cuff in such a way that the “φ” mark is at a location where the clearest pulsation of brachial artery is observed. The cuff should be tightened to a degree where insertion of one finger is allowed. The lower end of the cuff should be 2cm above the elbow joint. Figure 3.6 Cuff Position Safety Instructions for NIBP Monitoring When taking an infant or child’s (less than 10 years old) blood pressure measurement, ensure that the correct NIBP mode is selected prior to starting any measurement. Do NOT operate in the adult mode for Child or Infants. The high inflation pressure may cause lesion or tissue damage. It is recommended to take the blood pressure measurement manually. Automatic or continuous measurement should be used in the presence of a doctor/nurse if possible. NIBP monitoring is prohibited to those who have severe hemorrhagic tendency or with sickle cell disease, or partial bleeding will appear. Do NOT bind NIBP cuff on limbs with transfusion tube or IV Lines, Monitoring Sensors etc or skin lesion area, otherwise, damage may be caused to the limbs or Monitoring may be effected. Pay attention to the colour and sensitivity of the limb when measuring NIBP; make sure the blood circulation is not blocked. If blocked, the limb will discolour. Stop measuring or move the cuff to another position and inform a doctor. If the time of the automatic pattern non-invasive blood pressure measurement takes too long, the patient could possibly have purpura, lack blood or neuralgia. When checking the patient, you must inspect the colour, the warmth and the sensitivity of the body frequently. Once you observe any exception to normal patterns, immediately stop the blood pressure measurement. 12 The subject should sit or lie on their back so that the cuff and the heart are in the same horizontal plane and the most accurate measurement is taken. Other postures may lead to inaccurate measurement. Do not speak or move before or during the measurement. Care should be taken so that the cuff will not be hit or be touched by other objects. The measurements should be taken at appropriate intervals. Continuous measurement at too short intervals may lead to a compressed arm, reduced blood flow and lower blood pressure, resulting in inaccurate measurement of blood pressure. It is recommended the measure be taken at intervals of more than two minutes. When an adult subject is monitored, the machine may fail in giving the blood pressure measure if the infant mode is selected. Ensure the appropriate Patient Size Mode is selected prior to taking a reading. Prior to use, empty the cuff until there is no residual air inside it to ensure accurate measurement. Do NOT twist the cuff tube or put heavy things on it. When unplugging the cuff, hold the head of the connector and pull it out. The symbol indicates that the cable and accessories are designed to have special protection against electric shocks, and is defibrillator proof. Pressure Accuracy Verification Pressure Accuracy Verification is a function to inspect the accuracy of pressure measurement by the NIBP module inside the device. A qualified Technician should do pressure accuracy verification every 6 -12 months in order to check if the pressure measurement still conforms to the product performance specification. If the deviation is beyond the declared specification, t h e M o n i t o r s h o u l d b e returned to the Distributor for repair or calibration. Before verification, please connect the monitor to a standard calibrated pressure meter 0-300 + mmHg. Figure 3.7 Connection of Pressure calibration 13 Mode 1: the Monitor can activate the inflation so the pressure will increase automatically until it exceeds the limit value specified in table A. This pressure limit value depends on the patient type selections shown in table A: Adult 240mmHg Child 200mmHg Neonate 120mmHg Table A During inflation, the Monitor will close the deflating valve, and the pressure value will be shown during the process. If there is no manual deflation operation, the pressure will remain until deflation by manual operation, so it is necessary to use a manual valve for doing adequate deflation in several steps to verify the pressure accuracy in the full scale of measurement range. Mode 2: No automatic inflation by Monitor during the pressure accuracy verification. Increase the pressure manually by the pumping a hand held pressure bulb, and applying different pressure values manually to carry out the verification. If the increased pressure exceeds the given limit as shown in table B, the Monitor will deflate automatically because of over-pressure protection. These values should also be verified as part of the testing. Adult 300mmHg Child 240mmHg Neonate 140mmHg Table B After the verification, press the button again to return to normal working mode, then continue other operation, or the NIBP key will be invalid. Doctors or nurses are not allowed to do the verification; This is dangerous especially when the pressure cuff is still on the patient. Air Leakage Check In order to avoid significant error in blood pressure measurement or even no measurement result caused by air leakage in the pneumatic system, including the cuff during measuring, it is recommended to check if there is leak in the pneumatic system as well. Ensure the cuff is removed from the patient while performing the leakage check. 3.3.3 To connect the SpO2 Sensor Probe The SpO2 Sensor is a delicate piece of accessory. Please follow the steps and procedures for using it. Failure to use it correctly may effect accuracy of readings and may can cause damage to the SpO2 Sensor. User procedure: 8. Connect the SpO2 probe to the right panel’s jack labelled “SpO2”. When unplugging the probe, be sure to hold the head of the connector and pull it out. 9. Insert one finger into the probe (index finger, middle finger or ring finger with proper nail length) according to the finger mark on the probe, shown as below. 14 Figure 8 Demonstration for SpO2 probe When selecting a sensor, consider the patient’s category, adequacy of perfusion, availability of probe site and anticipated monitoring duration. Use only SpO2 probes provided by the Manufacturer with this monitor. Read the following table for SpO2 probe information. Refer to Chapter 13.8 or Individual Sensor IFU’s for the detailed instructions of each SpO2 probe. Use of Pulse Oximetry: High ambient light sources such as surgical lights (especially those with a xenon light source), bilirubin lamps, fluorescent lights, infrared heating lamps, and direct sunlight can interfere with the performance of a SpO2 sensor. To prevent interference from ambient light, ensure that the sensor is properly applied, and, if necessary, cover the sensor site with opaque material. Failure to take this action in high ambient light conditions may result in inaccurate measurements. If patient movement presents a problem, verify that the sensor is properly and securely applied; move the sensor to a less active site if possible; use an adhesive sensor that tolerates some patient motion; or use a new sensor with fresh adhesive backing. For reusable sensors, follow the sensor directions for use for cleaning and re-use. For single-patient use sensors, use a new sensor for each patient. Do not sterilize any sensor by irradiation, steam, or ethylene oxide. Safety Introductions for SpO2 Monitoring Continuous use of SpO2 sensor may result in discomfort or pain, especially for those with microcirculatory problem. It is recommended that the sensor should NOT be applied to the same place for over two hours. Change the measuring site periodically if necessary. Themeasuringsiteisgenerallychangedevery 2-3hours.Themeasuringsiteshouldbeinspected to ensure no abnormity every 1~2 hours. If abnormity occurs, change the measuring site periodically. Whentheambient temperatureisover35℃,pleasechangethemeasuringsiteeverytwohours if necessary. Burn hazard: When the ambient temperature is over 37℃, take special care. SpO2 measuringpositionmustbeexaminedmorecarefullyforsomespecialpatients. Do NOT install the SpO2 sensor on a finger with oedema or fragile tissue. Do NOT put the SpO2 sensor and pressure cuff on the same limb, otherwise the NIBP measuring will affect SpO2 measuring and cause an alarm error. If sterile packaging of SpO2 sensor is damaged, do not use it . Check the SpO2 sensor and cable before use. Do NOT use a damaged SpO2 sensor. If the temperature of SpO2 sensor is abnormal, do not use it any more Please do not use nail polish or other cosmetic product on the nail. The finger nail should be of normal length. Please do not allow the cable to be twisted, bent, impacted, cut or clamped. The SpO2 sensor cannot be immerged completely into water, liquor or cleanser, because the sensor is not waterproof. 15 3.3.4 Printer connection 1.

There is only one record every time when the NIBP measurement was taken. 5.3.2 Operating Instructions Up to 12000 groups of NIBP data can be memorized. Using the Navigation Knob allows the user to scroll the list up and down to view NIBP data. When rotating the knob anti-clockwise, the list scrolls upward. When rotating knob clockwise, the list scrolls down. Please note that when the groups of data are less than 6, the Navigation Knob cannot be used to scroll up or down the listing. Pressing “ 29 ”key to return to the Main Screen. 5.4 Graphic Trend Screen Figure 5.4 HR Trend 5.4.1 How to View the Graphic Trend Figure 5.4 is the HR trend graph. There are 3 options on the right of the graph, as described below. “HR” indicates the current trend graph is HR trend graph. If you want to enter other trend graphs, the procedures are: move cursor to “HR” and rotate the “Navigation Knob” to choose the trend graph from “HR”, “S-T”, “Temperature”, “NIBP”, “PR”, “RR” and “SpO2” trend graphs, next press the knob to confirm. Their screens are described in the following figures. After choosing “Cursor”, the trend graph displays a triangle and a vertical line, a moving ruler mark that can be moved by rotating the knob. As shown in the figure, when you move the mark to a specific point, the data area below the graph will display the time and its corresponding heart rate, respiration rate, SpO2, temperature. When rotating the “Navigation Knob” key to move the mark, the moving interval is a changing value. The rule is that the initial step is 5sec, after moving it towards the same direction once, the interval becomes 30 sec, and with more steps the interval becomes 1min, 10min and 30min. Therefore, it is very easy to find the time you are looking for. The “5 sec” on the top shows the interval time. Move the cursor to the trend time, press the knob and rotate it, and the trend graph time will change to 30 sec, 1 min, 10 min, 30 min, which changes the horizontal axis to be 30 min, 3 hour, 6 hours, 60 hours, 180 hours. For example, the monitoring can record 360 times data continuously when setting to “5 sec” within 30 minutes. Changing the interval time of 30 seconds, it can record 360 times data within 3 hours. Other changes are similar to that situation. The Trend graph shows the parameter value of the current time. For example, in the “5 sec” trend graph, the monitoring can record the current data with the interval of 5 seconds. Once the monitor is out of power, the data can be stored automatically and you can scan the history record when turning on the monitor next time. This ensures the screen always display the current data continuously. Other trend graph follows the same rule. Please note that the maximum value on the vertical axis of HR is 150, not the value of HR upper limit 300. The graph is scaled down for better viewing of the trend curve. When HR value exceeds 150, the vertical axis’s maximum value will automatically change to 300. That is to say, the vertical axis value 0-75-150 will change to 0-150-300 automatically if HR value exceeds 150. When the system is reset or the patient ID is changed, the vertical axis will return to its original value of 0-75-150. Other changes of vertical axis value in other trend graph are similar to that of HR. The respiration rate, body temperature and other trend graphs are similar to that of the HR’s and we will not cover them in detail again. Please note that for those trend graphs, the horizontal axis is the number of times the blood pressure is measured instead of time. 30 NIBP graphic trend is a little different from the other graphic trends. Rotate the knob to move the cursor to “ ”, then press the knob for activating this item. Next, rotate the knob left or right for viewing another 400 groups’ graphic trend.

Pressing “ key to return to the Main Screen. ” 5.5 Recall Screen Figure 5.11 Waveform Recall Screen It shows the monitoring can recall the history data continuously. If you change the patients’ ID or the monitor is out of power, the measuring data will not be a new single record, but will connect to the last record you have measured. It is a continuous loop recording. The ECG lead, gain and other parameters will not change during recall. Shown in Figure 5.12, it is different from the Main Screen in its 3rd trace of waveform area and the operation area. This is explained in detail below. Figure 5.12 Recall Listing 32 5.5.1 Operation Instructions Rotate the “Navigation Knob” and choose “Recall”, “HIST”, “Delete” or “Exit”. We explain the functions of each button below. Recall: Press the Recall and the first record in recall list becomes green. Rotate the knob to choose a record, and press the knob to recall it. The recalled waveform is displayed on the 3rd trace of the waveform area, as shown in Figure 5.13. Figure 5.13 Recalled Waveform Rotate the “Navigation Knob” to move forward or backward to review the waveform. Press the “Navigation Knob” to exit the waveform recall and return to the initial waveform recall screen. During waveform recall, the system not only displays the current recalled waveform, but also displays the lead status, gain and filter type of the waveform and time. HIST: Press the key to shift between the History key and Current key. Press HIST and the recall list on the left displays the history data list. Press the Current; the recall list on the left side displays the current one. When entering the recall screen, the system defaults to the current one.

Exit: Press this key to return to the System Menu screen. 33 5.6 Arrhythmia Screen Figure 5.14 Arrhythmia Screen 5.6.1 Operation Instructions The structure is similar to the recall screen. We will cover each function key below. This button is used to start and end the system Arrhythmia detection. The default is OFF. When the Arrhythmia is not ON, the “Learn” key is disabled. Press this key and the system enters learning mode. The Start changes to End. Press it again to end the learning. When “Learn” key changes to yellow from grey, it indicates the learning has finished. After the Arrhythmia detection begins, the system will automatically detect the Arrhythmia waveforms. If Arrhythmia is detected, the Arrhythmia waveform will be displayed in the 3rd trace of ECG waveform, shown in Figure 5.14. When the system is reset or the patient has changed, the Arrhythmia needs to be re- learned. Learn: Because the Arrhythmia detection is based on the normal ECG waveform at the same speed and same amplitude, when the patient changes, or the Arrhythmia detection is incorrect, the Arrhythmia needs to relearn. To make better use of the learn function, it is recommended to use a good ECG waveform to learn during monitoring. View: Press this key, and the selected record in the Arrhythmia list, which is to be reviewed, becomes green. Rotate the “Navigation Knob” to choose the record and display the corresponding waveform in the 3rd ECG channel. Press the knob again to exit. Exit: press this key to exit the Arrhythmia detection screen and return to the System Menu screen. Start: During monitoring, if Arrhythmia is detected, the system will alarm. The Arrhythmia alarm is system default and does not need setup. During Arrhythmia detection, incorrect detection might occur if the non-ECG waveforms (e.g.; square wave and triangle wave) appear. Before starting 1mV testing, please turn off the Arrhythmia detection. During Arrhythmia detection, the template of normal ECG waveform is very important, the system requires a group of stable ECG waveforms to build up the template. If the system detects the Arrhythmia incorrectly, please re-learn t h e t e m p l a t e by pressing “Learn” button and capture correct ECG waveform. 34 5.7 System Setup Screen Figure 5.15 System Setup 5.7.1 How to Select the System Setup Item Step 1: Step 2: Press “ rotate the knob to move the grey cursor to the corresponding item. press the knob to enter the corresponding setting screen: System Setup, Printer Setup, ECG Setup, TEMP setup, CO2 Setup, NIBP Setup, SpO2 Setup, RESP Setup or resuming Default setting.

In order to maximise the monitors battery life, please set CO2 switch at OFF state in system setup when the CO2 function is not used. Gain: theCO2 waveformgain. Unit: Choosing the EtCO2 and the minimum InsCO2. It can be set up as kPa, mmHg, and %. Baro (Barometric pressure): set ambient atmospheric pressure. It can be determined by barometer or the ambient altitude. Altitude can be used to determine the typical barometric pressure if a barometer is not available, refer to Appendix Typical Pressures and CO2 Readings at Altitudes for details. Zero: The method to calibrate CO2: Zero calibration. The CO2 module must have warmed up fully over 5 minutes continuous operation to ensure an accurate calibration. Use a large well ventilated room so that no CO2build up can be possible. Flow (CO2 flow): It is flow rate of the CO2 sampling. Its value is 50ml/min. The information promoted for Zero calibration is as follows: 43 Please apply the reference air with 0% CO2, the air in the well ventilated room usually can be regarded as the air with 0% CO2. Press “OK”, and the result will be displayed on the screen several seconds later. Apnea: display time of the respiration rate value in data area when the previous respiration has been detected while the next one is not, meanwhile, the device will prompt apnea information. The setting range is 10s~60s, the default is 20s. For example, if 20 seconds is set here, it means the respiration rate value will disappear after it has been shown for 20 seconds in the data area if no respiration is detected during this period. Period: setting the calculation cycle of EtCO2 value, there are three selectable options: “1b”, “10s” and “20s”. “1b”: means the EtCO2 value will be calculated once every respiration cycle; “10s”: means the EtCO2 value will be calculated once every 10s, and the maximum EtCO2 value measured during this 10s will be displayed on data area; “20s”: means the EtCO2 value will be calculated once every 20s, and the maximum EtCO2 value measured during this 20s will be displayed on data area TEMP: setting the temperature value of the current measured airflow. For instance, the temperature is usually set as 37℃ while measuring the patient’s respiration by airflow. However, if the airflow to be measured is the reference gas, the temperature is set as 25℃. The setting range: 0~50; Unit: ℃; Default value: 35.0. O2 Compen:adjusting the concentration of compensating gas in patient’s respiration airflow. Generally, the compensating gas is oxygen, so it can be called oxygen compensation concentration. The unit: %; Setting range: 0%~100%; Default value: 16. Balance: setting the balance gas in patient’s respiration airf low. There are three kinds of selectable balance gas: “Air”, “N2O” and “He”, namely: air, nitrous oxide and helium. If no specific balance gas is given; the balance gas can be set as “Air”. Agent: setting whether adding the anaesthetic agent gas to patient’s respiration airflow and the concentration of anaesthetic gas. The setting range is 0.0%~20.0%, the default status is: not adding anaesthetic gas, that is to say, the concentration is 0.0%. Respiration Rate High: Low: Setting the upper alarm limit of CO2 respiration rate. Setting the lower alarm limit of CO2 respiration rate. EtCO2 High: Low: Setting the upper alarm limit of EtCO2. Setting the lower alarm limit of EtCO2. InsCO2 High: Low: Setting the upper alarm limit of InsCO2.

Check all the applicable functions to make sure that the monitor works normally. If the built-in battery is applied please recharge it after using the monitor to ensure sufficient power storage. It will take minimal 8 hours to charge battery from depletion to 90% charge. Do not use the monitor to monitor the patient if there are indications of damage or reminders of error. Please contact the local dealer or our company. Start the monitor again 1 minute after it is switched off. 50 7.3 Blood Pressure Cuff Connection Connect the cable to the right-panel connector marked with the NIBP icon. Remove packaging and wrap the cuff around patient’s upper arm. 7.2.1 7.2.2 Requirements of the cuff: 1) 2) 3) 4) 5) 6) Appropriate cuff should be selected according to the age of the subject. Its width should be 2/3 of the length of the upper arm. The cuff inflation part should be long enough to permit wrapping 50-80% of the limb concerned. See the table below for the dimensions: Note: The size of the cuff selected should suit the subjects while measuring. Cuff Model Arm Circumference Cuff Width Neonate Cuff 6.0cm~9.5cm 3cm Small-sized Paediatric Cuff 6cm~11cm 4.5cm Middle-sized Paediatric Cuff 10cm~19cm 8cm Large-sized Paediatric Cuff 18cm~26cm 10.6cm Adult Cuff 25cm~35cm 14cm When putting on the cuff, remove packaging and wrap it around the upper arm evenly to appropriate tightness. Remember to empty the residual air in the cuff before the measurement is commenced. Locate the cuff in such a way that the “φ” mark is at a location where the clearest pulsation of brachial artery is observed. The cuff should be tightened to a degree where insertion of one finger is allowed. The lower end of the cuff should be 2cm above the elbow joint. Figure 3.6 Cuff Position Safety Instructions for NIBP Monitoring When taking the measure of an infant’s (less than 10 years old) blood pressure, do NOT operate in the adult mode. The high inflation pressure may cause lesion or even body putrescence. It is recommended to take the blood pressure measurement manually. Automatic or continuous measurement should be used in the presence of a doctor/nurse. NIBP monitoring is prohibited to those who have severe hemorrhagic tendency or with sickle cell disease, or partial bleeding will appear. Do NOT bind NIBP cuff on limbs with transfusion tube or intubations or skin lesion area, otherwise, damage may be caused to the limbs. Pay attention to the colour and sensitivity of the limb when measuring NIBP; make sure the blood circulation is not blocked. If blocked, the limb will discolour. Stop measuring or move the cuff to other positions and inform a doctor. If the time of the automatic pattern non-invasive blood pressure measurement takes too long, the patient could possibly have purpura, lack blood or neuralgia. 51 When checking the patient, you must inspect the colour, the warmth and the sensitivity of the body frequently. Once you observe any exception to normal patterns, immediately stop the blood pressure measurement. The subject should lie on their back so that the cuff and the heart are in a horizontal position and the most accurate measurement is taken. Other postures may lead to inaccurate measurement. Do not speak or move before or during the measurement. Care should be taken so that the cuff will not be hit or be touched by other objects. The measurements should be taken at appropriate intervals. Continuous measurement at too short intervals may lead to pressed arm, reduced blood flow and lower blood pressure, resulting in inaccurate measurement of blood pressure. It is recommended the measure be taken at intervals of more than two minutes. When an adult subject is monitored, the machine may fail in giving the blood pressure measure if the infant mode is selected. Prior to use, empty the cuff until there is no residual air inside it to ensure accurate measurement. Do NOT twist the cuff tube or put heavy things on it. The symbol indicates that the cable and accessories are designed to have special protection against electric shocks, and is defibrillator proof. Pressure Accuracy Verification Pressure Accuracy Verification is a function to inspect the accuracy of pressure measurement by the NIBP module inside the device. Technician or equipment manager should do pressure accuracy verification every half year or year in order to check if the pressure measurement still conforms to the requirement of product performance. If the deviation is beyond the declared specification, it is permitted to return it to factory for repair or calibration. Before verification, please connect the monitor to a standard pressure meter as the reference equipment like a mercury pressure meter. Figure 3.7 Connection of Pressure Verification Fixture 52 Mode 1: The inflation can be activated by Monitor so the pressure will increase automatically until it exceeds the limit value specified in table A. This pressure limit value depends on the patient type selection as shown in table A: Adult 240mmHg Child 200mmHg Neonate 120mmHg Table A During inflation, the Monitor will close the deflating valve, and the pressure value will be shown during the process. If there is no manual deflation operation, the pressure will remain until deflation by manual operation, so it is necessary to use a manual valve for doing adequate deflation in several steps to verify the pressure accuracy in the full scale of measurement range. Mode 2: No automatic inflation by Monitor during the pressure accuracy verification. Increase the pressure manually by the pumping balloon, and the verification can be done by applying different pressure value manually. If the increased pressure exceeds the given limit as shown in table B, the Monitor will deflate automatically because of over-pressure protection. Adult 300mmHg Child 240mmHg Neonate 140mmHg Table B After the verification, press the button again to return to normal working mode, then continue other operation, or the NIBP key will be invalid. Pressure accuracy verification must be operated by technician or equipment manager. Doctors or nurses are not allowed to do the verification, it is very dangerous especially when the pressure cuff is still on patients. Air Leakage Check In order to avoid significant error in blood pressure measurement or even no measurement result caused by air leakage in the pneumatic system, including the cuff during measuring, it is recommended to check if there is leak in the pneumatic system as well. Please remove the cuff from patient while performing the leakage check. 7.3 To connect the SpO2 SpO2 probe is very delicate accessory. Please follow the steps and procedures in operating it. Failure to operate it correctly can cause damage to the SpO2 probe. Operation procedure: 1. Connect the SpO2 probe to the right panel’s jack labelled “SpO2”. When unplugging the probe, be sure to hold the head of the connector and pull it out. 2. Insert one finger into the probe (index finger, middle finger or ring finger with proper nail length) according to the finger mark on the probe, shown as below. 53 Figure 3.8 Demonstration for SpO2 probe When selecting a sensor, consider the patient’s category, adequacy of perfusion, availability of probe site and anticipated monitoring duration. Use only SpO2 probes provided by our company with this monitor. Read the following table for SpO2 probe information. Refer to Chapter 13.8 for the detailed instructions of each SpO2 probe. SpO2 Probe Patient Category SpO2 Finger clip Sensor (reusable) Paediatric SpO2 Finger rubber Sensor(reusable) Adult SpO2 Finger clip Sensor(reusable) Adult High ambient light sources such as surgical lights (especially those with a xenon light source), bilirubin lamps, fluorescent lights, infrared heating lamps, and direct sunlight can interfere with the performance of a SpO2 sensor. To prevent interference from ambient light, ensure that the sensor is properly applied, and cover the sensor site with opaque material. Failure to take this action in high ambient light conditions may result in inaccurate measurements. If patient movement presents a problem, verify that the sensor is properly and securely applied; move the sensor to a less active site; use an adhesive sensor that tolerates some patient motion; or use a new sensor with fresh adhesive backing. For reusable sensors, follow the sensor directions for use for cleaning and reuse. For single-patient use sensors, use a new sensor for each patient. Do not sterilize any sensor by irradiation, steam, or ethylene oxide. Safety Introductions for SpO2 Monitoring Continuous use of SpO2 sensor may result in discomfort or pain, especially for those with microcirculatory problem. It is recommended that the sensor should NOT be applied to the same place for over two hours. Change the measuring site periodically if necessary. Themeasuringsiteisgenerallychangedevery3hours.Themeasuringsiteshouldbeinspected to ensure no abnormity every 1~2 hours. If abnormity occurs, change the measuring site periodically if necessary. Whentheambienttemperatureisover35℃,pleasechangethemeasuringsiteeverytwohours if necessary. Burn hazard: When the ambient temperature is over 37℃, do not use the SpO2 sensor for a long time. SpO2 measuringpositionmustbeexaminedmorecarefullyforsomespecialpatients. Do NOT install the SpO2 sensor on the finger with oedema or fragile tissue. Do NOT put the SpO2 sensor and pressure cuff on the same limb, otherwise the NIBP measuring will affect SpO2 measuring and cause an alarm error. 54 If sterile packaging of SpO2 sensor is damaged, do not use it any more. Check the SpO2 sensor and cable before use. Do NOT use the damaged SpO2 sensor. When the temperature of SpO2 sensor is abnormal, do not use it any more. Please do not allow the cable to be twisted or bent. Please do not use nail polish or other cosmetic product on the nail. The finger nail should be of normal length. The SpO2 sensor cannot be immerged completely into water, liquor or cleanser, because the sensor has no capability to resist the harmful ingress of water. 7.4 Printer connection 1.

The action potentials of cardiac-muscle cells can be viewed as batteries that cause charge to move throughout the body fluids. These currents represent the sum of the action potentials occurring simultaneously in many individual cells and can be detected by recording electrodes at the surface of the skin. The figure below shows the system of the heart. A common ECG plate electrode used together with this monitor has short shelf life. Generally, the shelf life is only one month after the package is opened. When outdated plate electrode is used, due to skin’s contact impedance and big electrode potential, the chance of interference will be increased, and the ECG baseline will have an unstable inclination. Therefore, always use valid plate electrodes. 12.1.2 Factors affecting ECG signal Interference from Electrosurgical Unit; Doesn’t filter the interference waveform; Poor grounding; Electrodesarenotplacedproperly; Use expired electrode or use disposable electrode repeatedly; The skin where the electrod is placed is unclean or has poor contract caused by grease/hair etc; Electrode has dried out or been used for too long. 71 12.2 Respiration Monitoring 12.2.1 Measuring Principle The air will be filled into alveolus or be expelled during respiration, and the chest’s volume changes with this process. Because the conductivity of air is lower than body tissues, the chest’s impedance will be changed by the inflation. With this specialisation, the respiration can be monitored through putting safe current into body and measuring the change of voltage between the electrodes. The product will transmit the high-frequency current whose frequency is much higher than ECG frequency (but with the safe current limit) to the ECG electrodes (placed at the both sides of chest), which can be detect ECG signal and chest’s impedance at the same time, and the respiratory rate will be measured through impedance method by the software. So the additional electrodes for respiratory measurement are unnecessary. 12.2.2 Factors affecting respiration monitoring Place the white (RA) and red (LL) electrodes on the cross, if the line between two electrodes in liver area or heart area, the artificial error may occur. Respiration monitoring doesn’tsupport monitoring patients who move too much, or may lead to the wrong alarm being given. 12.3 SpO2 Monitoring 12.3.1 Measuring Principle Based on Lamber-Beer law, the light absorbance of a given substance is directly proportional with its density or concentration. When the light with certain wavelength emits on human tissue, the measured intensity of light after absorption, reflecting and attenuation in tissue can reflect the structure character of the tissue by which the light passes. Because oxygenated haemoglobin (HbO2) and deoxygenated haemoglobin (Hb) have different absorption characters in the spectrum range from red to infrared light (600nm~1000nm wavelength), by using these characteristics, SpO2 can be determined. SpO2 measured by this monitor is the functional oxygen saturation -- a percentage of the haemoglobin that can transport oxygen. In contrast, hemoximeters report fractional oxygen saturation – a percentage of all measured haemoglobin, including dysfunctional haemoglobin, such as carboxyhemoglobin or metahemoglobin. 12.3.2 SpO2 Measurement Restrictions (interference reason) Intravascular dyes such as indocyanine green ormethylene blue Exposuretoexcessiveillumination,suchassurgicallamps,bili rubinlamps,fluorescentlights, infraredheating lamps,ordirectsunlight. Vascular dyes or external used colour-up product such as nail enamel or colour skin care Excessive patient movement Placement of a sensor on an extremity with a blood pressure cuff, arterial catheter, or intravascular line Exposuretothe chamberwithhighpressure oxygen There is an arterial occlusion proximal to the sensor Blood vesselcontractioncaused by peripheralvesselhyperkinesiasorbody temperature decreasing 72 12.3.3 Low SpO2 measuring value caused by pathology Hypoxemiadisease,functionallackofHbO2 Pigmentation or abnormal oxyhemoglobin level Abnormal oxyhemoglobin variation Methemoglobin disease Sulfhemoglobinemia or arterial occlusion exists near sensor Obvious venous pulsations Peripheral arterial pulsation becomes weak Peripheralbloodsupply isnotenough 12.3.4 Clinical Limitations As the measure is taken on the basis of arteriole pulse, substantial pulsating blood stream of subject is required. For a subject with weak pulse due to shock, low ambient/body temperature, major bleeding, or use of vascular contracting drug, the SpO2 waveform (PLETH) will decrease. In this case, the measurement will be more sensitive to interference. For those with a substantial amount of staining dilution drug (such as ethylene blue, indigo green and acid indigo blue), or carbon monoxide haemoglobin (COHb), or methionine (Me+Hb) or thiosalicylic haemoglobin, and some with icterus problem, the SpO2 determination by this monitor may be inaccurate. Thedrugssuchasdopamine,procaine,prilocaine,lidocaineandbutacainemayalsobeamajor factor blamed for serious error of SpO2 measurements. As the SpO2 value serves as a reference value for judgment of anemic anoxia and toxic anoxia, The measurement result of some patients with serious anaemia may also present as good SpO2 value. 12.3.5 Points to be noted in SpO2 and Pulse Measuring Thefinger should beproperly placed (see the attached illustration ofthis instruction manual),or elseitmaycause inaccuratemeasurementresult. Make sure that capillary arterial vessel beneath the finger is penetrated through by red and infrared lights. TheSpO2sensor should notbe used ata location or limb tied with arterial orblood pressure cuff or receiving intravenous injection. Do not fix the SpO2 sensor with adhesive tape, or else it may result in venous pulsation and consequential inaccurate measurement result of SpO2. Make sure the optical path is free from any optical obstacles like adhesive tape. Excessiveambient lightmay affectthe measuring result. Itincludes fluorescentlamp,dualruby light,infrared heater,and direct sunlightetc. Strenuousaction ofthe subjectorextremeelectrosurgical interferencemayalsoaffectthe accuracy. Please do not use the SpO2 sensor when having the MRI, or burn may be caused by faradism. Alwaysobservetheplethysmogram(waveform),whichisauto-scaledwithintherangeof100. The SpO2 reading may be unlikely true when the waveform is not smooth or irregular. If in doubt, rely on your clinical judgment, rather than the monitor readout. Afunctional tester can not be used to assess the accuracy of the pulse oximeter monitor or a SpO2 sensor. However, a functional tester, such as SpO2 simulator can be used to check how accurately a particular pulse oximeter is reproducing the given calibration curve. Before testing the oximeter by a functional tester, please firstly ask the manufacturer which calibration curve is used, if necessary, request the manufacturer for its dedicated calibration curve and download it into the tester. 73 12.3 Temperature Monitoring The sensor is thermo-resistor type (25℃ 5kΩ) and is supplied with constant micro current. Calculating the temperature of measured part through measuring the voltage. There is a period responding time, so the accurate temperature value display after a while. The temperature monitoring can be divided into two measuring method: measure through body surface temperature and through the temperature inside the body cavity (placed in mouth or anus). Normal value: body surface: 36.5℃~37℃; inside body cavity: 36.5℃~37.7℃. Notes: When attaching the TEMP transducer to the patient, make sure the transducer is attached correctly as this could affect TEMP reading. Take special care and time with attaching to paediatric patients. 12.4 CO2 Monitoring 12.4.1 Measuring Principle The principle is based on the fact that CO2 molecules absorb infrared light energy of specific wavelengths, with the amount of energy absorbed being directly related to the CO2 concentration. When an IR light beam is passed through a gas sample containing CO2, the electronic signal from a photodetector (which measures the remaining light energy), can be obtained. This signal is then compared to the energy of the IR source, and calibrated to accurately reflect CO2 concentration in the sample. When calibrated, the photo-detector’s response to a known concentration of CO2 is stored in the monitor’s memory. The monitor determines CO2 concentration in the breathing gases by measuring the amount of light absorbed by these gases.EtCO2 is displayed as a numerical value in millimeters of mercury (mmHg), percent (%), or kilopascals (kPa). In addition, a CO2 waveform (capnogram) may be displayed which is a valuable clinical tool that can be used to assess patient airway integrity and proper endotracheal tube placement. Respiration rate is calculated by measuring the time interval between detected breaths. 12.4.2 Mainstream vs. Side stream Sampling Mainstream CO2 sensors are placed at the airway of an intubated patient, allowing the inspired and expired gas to pass directly across the IR light path. The major advantages of mainstream sensors are fast response time and elimination of water traps. Side stream CO2 sensors are located away from the airway, requiring a gas sample to be continuously aspirated from the breathing circuit and transported to the sensor by means of a pump. This type of system is needed for non-intubated patients. When using mainstream CO2 sensors, check the window for secretions as pooled secretions may affect the accuracy of the measurement or even prevent the sensor from working. When using side stream CO2 sensors, there is a water trap or a part of the sampling tube with dehumidifying function. Please periodically check the flow sensor and tubing for excessive moisture or secretion build-up. 74 12.5 NIBP Monitoring 12.5.1 Measuring Principle Blood pressure may be measured in an invasive way (whereby the sensor will be inserted into blood vessel directly) or a non-invasive way. The non-invasive way includes several methodologies, such as the Korotkoff Sound Method and oscillating method. The Korotkoff Sound Method is used as a conventional way, whereby stethoscope is used to measure the blood pressure. By the oscillating method, an inflation pump will fill the air, and release it slowly. A computer will record change of the cuff pressure when the air is released. With this record, the blood pressure value will be determined. First of all, make sure the signal quality judgment by computer meets the requirements of accurate calculation (such as sudden limb movement or cuff being hit during the measurement). If the answer is negative, give up the calculation. If the answer is positive, proceed with calculation of the blood pressure value. As change of the blood pressure is recorded by electric sensor, which sensitivity is much higher than that of human ears, the oscillating method uses different definitions for measurement of diastolic pressure, mean arterial pressure and systolic pressure from the Korotkoff Sound Method. When the oscillating method is used, the circuit in the measuring apparatus will separate the amplitude of the cuff pressure from its change with pulsation. With the oscillating method, the blood pressure at the maximum amplitude of cuff pressure is defined as the mean arterial pressure. The blood pressure at amplitude of cuff pressure forward reduced according to proper proportion is defined as systolic pressure, while the blood pressure at amplitude of cuff pressure backward reduced according to proper proportion is defined as diastolic pressure. The maximum change of pulse pressure occurs at these two points. They are equivalent to the point with pulse sound and the point without pulse sound respectively in the Korotkoff Sound Method. When the risk of invasive monitoring method outweighs its advantage of accuracy, non-invasive monitoring method shall be used. Comparison between blood pressure measuring methods To overcome the effect of human hearing variation and air release speed on measurement accuracy when the conventional Korotkoff Sound Method is used to take measure of blood pressure, people have been dedicated to study of automatic measurement of blood pressure. By now, automatic blood pressure measuring system based on the principle of oscillating method is mature. In practice, however, various problems are encountered, such as why the measures taken by the oscillating method is lower or higher than those taken by Korotkoff Sound Method? Why the measures are inclined to decline? Why, in some cases, no result is obtained in spite of the inflation actions? Why the measure values have big discreteness and even abnormal data in some cases? Why the SpO2 waveforms may disappear suddenly? ...and so on. The following explanations are devised to give the answers. The Oscillating method vs. the Korotkoff Sound Method Blood pressure measurement by the oscillating method and Korotkoff Sound Method has good correlation with the invasive measurement. Notwithstanding, any of the non-invasive blood pressure measurements has its onesidedness when it is compared to the invasive measurement. The oscillating method has its advantages over the Korotkoff Sound Method in less error, higher reliability and stability. Their differences may be reflected in the following aspects. The measures by the Korotkoff Sound Method are liable to affect human factors. For example, different people may have different sound judging ability, or different reactivity when listening to heart sound and reading mercury meter. The air release speed and subjectivity may also affect the judgment. By the oscillating method, the computation is accomplished by the computer, thus relieving the possibility of effect due to human factor. With the Korotkoff Sound Method, the measure is taken on the basis of appearance and disappearance of heart sound. The air release speed and heart rate may have direct effect on the measurement accuracy. It also has the disadvantages of rapid air release and poor accuracy. In the contrast, with the oscillating method, the determination is calculated on the basis of cuff pressure oscillatory waveform envelope, and the air release speed and heart rate has little effect on the measurement accuracy. 75 Statistics show that, when measuring the hypertension, the measure taken by the oscillating method is likely to be lower than that taken by the Korotkoff Sound Method. When measuring the hypotension, the measure taken by the oscillating method is likely to be higher than that by the Korotkoff Sound Method. But, it doesn’t mean the advantages or disadvantages between the oscillating method and the Korotkoff Sound Method. Comparison with the results taken by more accurate method, let’s say comparison of the invasive pressure result with the output value by the blood pressure measuring simulator, will show which method has more accurate results. In addition, higher or lower value should be a statistical concept. It is recommended those used to adopt the Korotkoff Sound Method use different physiological calibration for values determined by the oscillating method. The studies have shown that the Korotkoff Sound Method has the worst accuracy when it comes to measurement of hypotension, while the oscillating method has worse accuracy when it comes to measurement of controlled hypertension relief. 12.5.2 Factors affecting NIBP measuring Select a cuff of appropriate size according to the age of the subject. Its width should be 2/3 of the length of the upper arm. The cuff inflation part should be long enough to permit wrapping 50-80% of the limb concerned. Prior to use of the cuff, empty the cuff until there is no residual air inside it to ensure accurate measurement. Make the cuff mark φ in the position where artery pulsates obviously, the effect will be best. The lower part of cuff shall 2cm above the elbow joint. Do not wrap the cuff on too thick clothes (especially forcotton-padded clothes and sweater ) to take measurement; The tester should lie in bed or sit in chair, make the cuff and heart at the same level, for most accurate results, other postures may have inaccurate result. During measuring, do not move your arm or the cuff. Themeasuring interval should be longer than 2 minutes, in continuous measurement, too short intervalmaycause armextrusion,bloodquantityincreases,thencausebloodpressureincreases. Keep the patient still and stop talking before and during measuring. Thepatient’smood alsocanaffectthe measuringresult,whenexcited,theblood pressuregoes up. The measuring result is also affected by time, lower in the morning and higher in the evening. 12.5.3 Clinical Limitations 1. 2. 3. 4. 5. 6. Serious angiospasm, vasoconstriction, or too weak pulse. When extremely low or high heart rate or serious arrhythmia of the subject occurs. Especially auricular fibrillation will lead to unreliable or impossible measurement. Do not take the measurement when the subject is connected with an artificial heart-lung machine. Do not take the measurement when the subject uses diuresis or vasodilator. When the subject is suffering from major haemorrhage, hypovolemic shock and other conditions with rapid blood pressure change or when the subject has too low body temperature, the reading will not be reliable, for reduced peripheral blood flow will lead to reduce arterial pulsation. Subject with hyperadiposis; In addition, statistics show that 37% people report blood pressure difference of no less than 0.80kPa(6mmHg) between the left and right arms, and 13% people report difference of no less than 1.47kPa (11mmHg). Note: Some practitioners may report big discrepancies or abnormal values of the blood pressure measures when the oscillating method is used. As a matter of fact, the so-called “big discrepancy” must be a term in the sense of statistical significance of mass data. Abnormal data may be observed in some individual cases. It is normal in the scientific experiments. It may be caused by an apparent reason, or by an unknown factor in some cases. Such individual doubtful experimental data may be identified and eliminated using the special statistical technique. It is not a part of this manual. The practitioner may eliminate the apparently unreasonable data according to the experience 76 Chapter 13 Appendix 13.1 Alarm Information Alarm Information Descriptions Over HR limit Over TEMP limit Over RR limit Over SpO2 limit Over PR limit Over NIBP SYS limit The related parameter value exceeds the preset high/low alarm limit.

In this case, it is not allowed to monitor infant patient. Otherwise, there may be serious danger to the infant monitored. — The blood pressure module is now worked in infant measuring mode. — SpO2 probe fell off — The ECG electrodes or cable fell off —Learning arrhythmia for 15 seconds — The monitor is displaying the demo waveforms, which are generated by the monitor itself. 80 13.5 Status/Error during CO2 Monitoring Suggested Message/Response Description “Sensor Over Temp” Make sure sensor is not exposed to extreme heat (heat lamp, etc.). If error persists, return sensor to factory for servicing. The sensor temperature is greater than 40 °C “Sensor Faulty” Check that the sensor is properly plugged in. Reinsert or reset the sensor if necessary. If error persists, return sensor to factory for servicing One of the following conditions exist: Source Current Failure, EEPROM Checksum Faulty, Hardware Error No Parameter Message The host must set the Barometric Pressure compensations to clear this error; no user intervention should be required. Barometric Pressure and/or gas compensations have not been set since power and on. For CO2 to be calculated with the stated accuracy, these values should be set whenever the sensor is plugged in. “Module in Sleep Mode” This bit is set when sensor has been placed in sleep mode. “Zero In Progress “ A Module Zero is currently in progress. “Sensor Warm Up” This error condition is normal at start-up. This error clear when the warm up is complete. One of the following conditions exist: should Sensor under temperature, Temperature not stable or Source Current unstable “Check Sampling Line” Check that the sampling line is not occluded or kinked. This error occurs whenever the pneumatic pressure is outside the expected range. “Zero Required” To clear, check airway adapter and clean if necessary. If this does not correct the error, perform an adapter zero. If you must zero adapter more than once, a possible hardware error may exist. One of the following conditions exist: Zero Required; Zero Required: Zero Error “CO2 Out of Range” If error persists, perform a zero. The value being calculated is greater than the upper CO2 limit (150 mmHg, 20.0 kPa, or 19.7%). The maximum value output is the upper CO2 limit. “Check Airway Adapter” To clear, clean airway adapter if mucus or moisture is seen. If the adapter is clean, perform Capnostat zero. Usually caused when the airway adapter is removed from the sensor or when there is an a optical blockage on the windows of the airway adapter. May also be caused by failure to perform sensor zero to when adapter type is changed. The Sensor not Ready This is prompted if the CO2 sensor is not ready for a Capnostat Zero. If the “Zero Required” and this massage both prompt message both promp one or more of the following conditions may exist: • Breaths detected • Temperature is not stable • Source Current unstable • In sleep mode. Zero already in progress Normal zero calibration is already in progress. Zero Fault and Breaths Detected Zero attempted and breaths have been detected in the last 20 seconds.

Contraindications This sensor is contraindicated for use on active patients or for prolonged use. Instructions for Use 1) With the upper and lower jaws open, place an index finger evenly on the base of the clip. Push the fingertip against the stop so that it is over the sensor window (A). If an index finger cannot be positioned correctly, or is not available, other fingers can be used. 2) Note: When selecting a sensor site, priority should be given to an extremity free of an arterial catheter, blood pressure cuff, or intravascular infusion line. 3) Spread open the rear tabs of the sensor to provide even force over the length of the pads (B). 4) 5) 6) 7) The sensor should be oriented in such a way that the cable is positioned along the top of the hand (C). Plug the sensor into the oximeter and verify proper operation as described in the user manual. Inspect the monitoring site every 1~2 hours for skin integrity. Before each use, surface-clean sensor and cable with a soft gauze pad by saturating it with a solution such as 70% isopropyl alcohol. If low-level disinfection is required, use a 1:10 bleach solution. Caution: Do not sterilize by irradiation steam, or ethylene oxide. Warnings 1) Some factors may affect the accuracy of saturation measurements. Such factors include: excessive patient motion, fingernail polish, use of intravascular dyes, excessive light, poor blood perfusion in the finger, extreme finger sizes or improper placement of the sensor. 2) Using the sensor in the presence of bright lights may result in inaccurate measurements. In such cases, cover the sensor site with an opaque material. 3) The sensor must be moved to a new site at least every 3 hours. Because individual skin condition affects the ability of the skin to tolerate sensor placement, it may be necessary to change the sensor site more frequently with some patients. If skin integrity changes, move the sensor to another site. 4) Do not apply tape to secure the sensor in place or to tape it shut; venous pulsation may lead to inaccurate saturation measurements. 5) Do not immerse sensor as it causes short. 6) Do not use NIBP or other constructing instruments on same appendage as sensor for blood flow interrupted by NIBP cuff or circulatory patient condition will result in no pulse found or loss of pulse. 7) Do not use the sensor or other oximetry sensors during MRI scanning. 8) Carefully route cables to reduce the possibility of patient entanglement or strangulation. 9) Do not alter or modify the sensor. Alterations or modifications may affect performance or accuracy. 10) Do not use the sensor if the sensor or the sensor cable appears damaged. 85 Instructions for Adult SpO2 Finger Rubber Sensor Intended Use When used with a compatible Multi-parameter Monitor or a pulse oximeter device, this SpO2 sensor is intended to be used for continuous, non-invasive functional arterial oxygen saturation (SpO2) and pulse rate monitoring for patients weighing greater than 50kg. Contraindications This sensor is contraindicated for use on active patients or for prolonged use. Instructions for Use 1) 2) 3) 4) Hold the sensor with its opening towards the patient’s index finger (A). The sensor should be orientated in such a way that the sensor side with a finger tip sign is positioned on the top. Insert the patient’s index finger into the sensor until the fingernail tip rests against the stop at the end of the sensor. Adjust the finger to be placed evenly on the middle base of the sensor. Direct the cable along the top of the patient’s hand. Apply adhesive tape to secure the cable (B). If an index finger cannot be positioned correctly, or is not available, other fingers can be used. Plug the sensor into the oximeter and verify proper operation as described in the user manual. Inspect the monitoring site every 1~2 hours for skin integrity. Cleaning & Disinfection Unplug the sensor before cleaning or disinfecting. Surface-clean sensor and cable with a soft gauze pad by saturating it with a solution such as 70% isopropyl alcohol. If low-level disinfection is required, use a 1:10 bleach solution. Caution: Do not sterilize by irradiation steam, or ethylene oxide. Warnings 1) This sensor is for use only with compatible Monitors or pulse oximeter devices. Use of this sensor with instruments other than compatibles may result in improper performance. 2) Some factors may affect the accuracy of saturation measurements. Such factors include: excessive patient motion, fingernail polish, use of intravascular dyes, excessive light, poorly perfused finger, extreme finger sizes or improper placement of the sensor. 3) The sensor site must be checked for skin integrity at least every 1~2 hours. Because individual skin condition affects the ability of the skin to tolerate sensor placement, it may be necessary to change the sensor to another finger. 4) Do not use NIBP or other constructing instruments on same appendage as sensor for blood flow interrupted by NIBP cuff or circulatory patient condition will result in no pulse found or loss of pulse. Do not use the sensor during MRI scanning. 5) Carefully route cables to reduce the possibility of patient entanglement or strangulation. 6) Do not alter or modify the sensor. Alterations or modifications may affect performance or accuracy. 7) Do not use the sensor if the sensor or the sensor cable appears damaged. 86 Instructions for Adult SpO2 Finger Clip Sensor Intended Use When used with a compatible patient Multi-parameter Monitor or a pulse oximeter device, the sensor is intended to be used for continuous, non-invasive functional arterial oxygen saturation (SpO2) and pulse rate monitoring for patients weighing greater than 40kg.
