Introduction Welch Allyn Spot Vital Signs

Blood pressure cautions

Caution Extremity and blood pressure cuff motion should be minimized during blood pressure determinations.

Caution If the blood pressure cuff is not at heart level, the difference in reading due to the hydrostatic effect should be noted. The value of 1.80 mmHg must be added to the displayed reading for every inch (2.5 cm) above heart level. The value of 1.80 mmHg must be subtracted from the displayed reading for every inch (2.5 cm) below heart level.

Caution Proper blood pressure cuff size and placement is essential to the accuracy of the blood pressure determination.

Caution When measuring blood pressure on children younger than 3 years of age, it is recommended that the Pressure Preset (initial inflation pressure) be set at 160 mmHg or lower.

SpO

cautions

Caution The pulse oximeter is calibrated to determine the percentage of arterial oxygen saturation of functional hemoglobin. Significant levels of dysfunctional hemoglobin such as carboxyhemoglobin or methemoglobin may affect the accuracy of the measurement.

Caution Physiological conditions, medical procedures, or external agents that may interfere with the pulse oximeter’s ability to detect and display measurements include dysfunctional hemoglobin, arterial dyes, low perfusion, dark pigment, and externally applied coloring agents such as nail polish, dye, or pigmented cream.

Caution Some sensors may not be appropriate for a particular patient. If at least

15 seconds of perfusion pulses cannot be observed for a given sensor, change sensor location or sensor type for perfusion to resume.

Caution When selecting a sensor, consider the patient’s weight and activity level, the adequacy of perfusion, the available sensor sites, the need for sterility, and the anticipated duration of monitoring.

Temperature cautions

Caution The Welch Allyn Spot Vital Signs is FDA cleared to measure the axillary temperature in Normal Mode for children under the age of 4. Normal Mode axillary temperatures may not be accurate on older children or adults. THE

Service Manual

Electrostatic discharge (ESD)

Introduction

7

Electrostatic discharge is a sudden current flowing from a charged object to another object or to ground. Electrostatic charges can accomulate on common items such as foam drinking cups, cellophane tape, synthetic clothing, untreated foam packaging material, and untreated plastic bags and work folders, to name only a few.

Electronic components and assemblies, if not properly protected against ESD, can be permanently damaged or destroyed when near or in contact with electrostatically charged objects. When you handle components or assemblies that are not in protective bags and you are not sure whether they are static-sensitive, assume that they are static-sensitive and handle them accordingly.

• Perform all service procedures in a static-protected environment. Always use techniques and equipment designed to protect personnel and equipment from electrostatic discharge.

• Remove static-sensitive components and assemblies from their static-shielding bags only at static-safe workstations - a properly grounded table and grounded floor mat - and only when you are wearing a grounded wrist strap (with a resistor of at least 1 megohm in series) or other grounding device.

• Use only grounded tools when inserting, adjusting, or removing static-sensitive components and assemblies.

• Remove or insert static-sensitive components and assemblies only with monitor power turned off.

• Insert and seal static-sensitive components and assemblies into their original staticshielding bags before removing them from static-protected areas.

Always test your ground strap, bench mat, conductive work surface, and ground cord before removing components and assemblies from their protective bags and before beginning any disassembly or assembly procedures.

Functional verification

Complete all steps in this section before returning a Spot Vital Signs for service.

Verify that the pressure meter used (if not specified by this service manual) is calibrated and the calibration certificate of the meter is traceable to NIST. The pressure meter testing the Spot Vital Signs must have an accuracy of better than

"

3 mmHg.

Subtract the rated accuracy of the pressure measurement standard from the

"

3 mmHg rated accuracy of Spot Vital Signs. This is the pass/fail criteria to determine if the device is within calibration. If the differences between Spot Vital Signs and the pressure measurement standard are within the pass/fail criteria at all specified pressures, then the device is within calibration.

All test specifications are found in Appendix A.

1.

Patient’s arm position

Arm movement during blood pressure cycle

Blood pressure taken over clothing

Arrhythmia

Explanation and Corrective Action

Determine correct blood pressure cuff size.

• Use reference markings on blood pressure cuff.

• Measure patient’s arm circumference midway between elbow and shoulder to select correct blood pressure cuff size).

Ensure patient’s arm is at heart level.

Keep arm still during blood pressure cycle.

• Movement may cause inaccuracies from artifact.

Take blood pressure on a bare arm.

Check for regularity of heart rate (palpate pulse or check device).

• Moderate to severe heart rate irregularities may make blood pressure difficult to measure.

Service Manual Troubleshooting

31

Table 8. Inaccurate Blood Pressure Readings

Possible Cause

Incorrect reference

Explanation and Corrective Action

Use the correct Korotkoff sound to determine diastolic blood pressure.

• Many listeners incorrectly equate diastolic blood pressure with the disappearance of sound only (phase 5). The Welch Allyn Spot Vital Signs was developed using the American Heart Association recommendations, which state that phase 5 be used unless sound continues to 0 mmHg, in which case the change in the quality of sound (phase 4) is to be used.

Deflate blood pressure cuff no faster than 3 mmHg per second.

• One of the major sources of error in auscultatory blood pressure measurement is deflating the blood pressure cuff too quickly. The American Heart Association recommends deflation no faster than 3 mmHg per second.

Only use a sphygmomanometer that is calibrated.

• An uncalibrated sphygmomanometer may take inaccurate blood pressure measurements.

Change in blood pressure between auscultatory reading and Welch Allyn Spot Vital

Signs reading

Poor auscultatory sound recognition by observer

Check blood pressure immediately prior to Welch Allyn Spot Vital Signs reading.

Use higher quality stethoscope. Have a different observer check patient’s blood pressure.

Note: Differences of up to 10 mmHg are considered normal and occur for a number of reasons including intra-patient blood pressure variability, observer hearing differences, and auscultatory deflation rate.

Table 9. Cuff Inflation and Deflation with No Blood Pressure Reading Displayed (or Error Code in

Technical overview

System description

The Spot Vital Signs automatically measures systolic and diastolic blood pressure, pulse rate, pulse oximetry (SpO

2

), and temperature (oral, axillary under 4 years, and rectal) for adult and pediatric patients (excluding neonates).

The device is intended to be used by clinicians and medically qualified personnel. It is available for sale only upon the order of a physician or licensed health care provider.

Refer to the Spot Vital Signs Directions for Use manual for complete information.

Battery /charge system

Spot Vital Signs includes a 6 Volt, 4.5 amp-hour sealed lead-acid battery that supplies all power to the device. A polarized connector protects against reversing the battery connection. An external power supply charges the battery and can operate Spot Vital

Signs at the same time. The external power supply provides the Spot Vital Signs with up to 1000mA at 7.2VDC. As the battery charges, the energy required to charge it decreases and the external power supply voltage rises to 8 VDC while supplying 750mA. The voltage to the external power supply is approximately 12.5VDC with no load attached. The Spot

Vital Signs monitors the battery voltage to control the fast and trickle charge modes. The

CPU allows fast charge until the battery reaches approximately 7.0 VDC, and then the CPU switches the charger circuit to trickle charge mode. For a dead battery the external charger supplies sufficient power to allow the Spot Vital Signs to power on, but not enough energy for a blood pressure cycle. A 5 amp surface mount fuse is populated on the Spot

Vital Signs main board at location F301.

Main CPU power supply

A single +5VDC linear regualtor (U319) powers the CPU and provides power to other digital circuitry on the main printed circuit board.

Clock/calendar power

The battery directly powers the internal real time clock (U309) through a voltage divider.

The Spot Vital Signs always has power if a battery is connected. A 100uF capacitor (C308) delivers energy to the real time clock during a battery exchange. If the battery is disconnected for longer than 1 minute, reset the real time clock after restoring the battery power.

51

52

Technical overview Welch Allyn Spot Vital Signs

Mod B NIBP power

The main board contains the circuitry required for blood pressure measurement. The main

CPU controls the battery power to this module through a +5V linear regulator (U6). In the event of a critical blood pressure module error, the main CPU disconnects power from the

ModB module through the BPEN signal at Q11. A separate +5V linear regulator (U1) powers the ModB analog circuitry to keep digital signal noise separated from the analog components.

Thermometer power

A combination of the main CPU +5V and the ModB +5V supply the SureTemp thermometer circuitry. If the main CPU disconnects power from the ModB blood pressure circuitry then the SureTemp circuitry is also disabled.

SpO

2

power

The battery supplies power to the SpO

2

through a +5V linear regualtor (U322). If there is no SpO

2

module connected to the Spot Vital Signs main board the SpO2 power supply is disconnected.

LCD power

The main CPU supplies power to the LCD module through the J307 connector, and the

FET Q312 and comparator U324A control the backlight. This comparator and FET create a pulse width modulated signal that allows the backlight to maintain constant brightness during changing battery voltages. The white backlight LEDs are connected in series inside the LCD module. This configuration causes some LEDs to look brighter or dimmer than adjacent LEDs. This is normal and expected.

Communications

A Spot Vital Signs and computer can communicate through the IR or service communication ports. IR communication is the default mode and works as a standard serial port (9600 baud, 8 data bits, no parity, 1 stop bit, no flow control) when used with

Welch Allyn 130S57E communications kit. The hard-wired service port is positioned behind the battery. Connect the port as described in the interconnect diagram. The hardwired port is intended for service use only. Never use the hard-wire communications port while the device is connected to a patient because it has no patient isolation protection.

When the pressure transducer calibration is performed (only when successful), a calibration signature (four printable characters) and the calibration date/time is stored in the Spot Vital Signs memory - any of four printable characters.

Pneumatic accuracy test

Enter the Internal Configuration Mode to perform this test (see “Internal configuration mode” on page 20).

Perform an Auto-zero before starting this test (

“To verify the blood pressure calibration:” ,

Step 1 on page 27 through Step 4 on page 27). The Pneumatic Accuracy test is defined as

the comparison of Spot Vital Signs pressure measurement and applied pressure at 0, 50,

150, and 250 mmHg. The specification for each reading is within ±3 mmHg of the target pressure except for the 0 mmHg reading which is within ±1.0 mmHg.

Valve control test

Connect a 100 cc cylinder to the Spot Vital Signs pressure port and pressurize to 160 mmHg. Give Spot Vital Signs the commands to open the valve for 10 mmHg/s, 15 mmHg/ s, and 25 mmHg/s. Record each pressure drop: 4 to 12 mmHg, 4 to 15 mmHg, and 4 to

25mmHg, respectively.

Voltage calibration

Calibrate the Spot Vital Signs battery voltage measurement circuit at 5.5 Vdc (+0.1/-0.0

Vdc). Verify the battery calibration factor is 14,384 to 18,384. (?)

After performing a successful battery measurement circuit calibration, Spot Vital Signs memory will store a calibration signature of up to four printable characters.

Blank mode current test

The Blank Mode Current Test is defined as the amount of current drawn through the battery terminals. All LCD segments, the back light, and the SpO

2

mode are all turned off.

The limit is 200 mA maximum.

Back light (Idle) current test

The Back Light Current Test is defined as the amount of current drawn through the battery. All LCD segments and the back light are turned on while the SpO

2

mode is turned off. The limit is 400 mA maximum.

Valve/pump mode current test

The Valve/Pump Mode Current Test is defined as the amount of current that is drawn through the battery terminals; Spot Vital Signs is in the Blank Mode while the valve and pump are actuated to on. The limit is 700 mA maximum.

Interface test

When given the proper commands, the Display Window will turn on or off all segments and turn on or off the back light. When given the proper command, the buzzer sounds to verify operation. The user determines the pass/fail criteria.

Temperature option requirements

Accuracy test

Verify the accuracy of the temperature module is within ±0.2° F for readings with a nomal temperature of 97.3° F (36.3° C) using a Cal Key (5200-25). Verify Spot Vital Signs can read a temperature of 96.4° F (35.8° C) and 106° F (41.1° C) within ±0.3° F/±0.2° C using a

Welch Allyn 9600 Plus Calibrator.

If using a water bath to take temperatures, verify the bath themperature is between 84° F and 106°F/28.8°C and 41.1°C. The reading must agree within (±1.0° F/0.8° C) measuring against a temperature stated that is accurate to within (±1.0° F/0.8° C).

Temperature probe test

Spot Vital Signs displays “188.8” and then “ORL” after you remove the oral probe from the probe housing.
