Unless otherwise specified, from this point onwards the term spirolab III is used to refer to both models.
1 GENERAL INFORMATION
1.1 I
NTENDED USE
Spirolab III spirometer and pulse oximeter is intended to be used by either a physician, respiratory therapist or technician.
The device is intended to test lung function and can make:
spirometry testing in people of all ages, excluding infants and neonates
oximetry testing in people of all ages.
It can be used in any setting.
1.1.1 User Category spirolab
III, spirometer + pulse oximeter calculates a series of parameters relating to human respiratory function.
1.1.2 Ability and experience required
The correct use of the device, the interpretation of the results and the maintenance of the device, with particular WARNING on cleaning operations (cross-contamination risk), all require qualified personnel.
WARNING
MIR cannot be held responsible for any damage caused by the user of the device failing to follow the instructions and warnings contained in this manual.
If the user of spirolab III is a person considered to be cognitively impaired, then the operation of the device must be made under the supervision and responsibility of whoever is legally charged with the supervision of this person.
The
spirolab
III
when used as a pulse oximeter is intended for spot-checking, overnight sleep screening and/or continuous monitoring when attended by a trained healthcare professional.
1.1.3 Operating environment
The device has been envisaged for use in a doctor‟s office or in a hospital setting.
The information necessary for the proper use of the device in surrounding electromagnetic environments (as required by EN 60601-1-2) is contained in the Annex.
spirolab
III – User Manual Code MIR 980067 REV 2.0 Page 6 / 74
The device is not intended for use in an operating theatre nor in the presence of inflammable liquids or detergents, nor in the presence of inflammable anaesthetic gases
(oxygen or nitrogen).
The device is not designed to be used in direct air currents (e.g. wind), sources of heat or cold, direct sun rays or other sources of light or energy, dust, sand or any other chemical substances.
The user and/or the doctor are responsible for ensuring that the device is stored and used in appropriate environmental conditions; in this regard reference is made to the specifics described in paragraph 1.5 below.
WARNING
If the device is exposed to unsuitable environmental conditions, this could cause the device to malfunction and to give incorrect results.
1.1.4 Who can or must make the installation
The device requires installation by qualified personnel. The user shall normally configure the device accordingly.
1.1.5 Subject effect on the use of the device
A spirometry test should only be carried out when the subject is at rest and in good health, and thus in a suitable condition for the test. A spirometry test requires the collaboration of the subject, since the subject must make a complete forced expiration, in order to have a meaningful test result.
1.1.6 Limitations of use - Contraindications
An analysis of the results of a spirometry test is not by itself sufficient to make a correct diagnosis of the subject‟s clinical condition. Test comments, a test interpretation and suggested courses of treatment must be given by a doctor.
Any symptoms that the subject has at the time must be carefully considered before a spirometry test is made. The user is responsible to assess both the mental and the physical capacity of the subject to make a correct test and the user must also assess the degree of collaboration for each test carried out.
A correct spirometry test requires the complete collaboration of the subject. The results depend on the person‟s capability to inspire and to expire all air completely and as fast as possible. If these fundamental conditions are not respected then the results obtained during spirometry testing will not be accurate, and therefore the test results are "not acceptable".
The acceptability of a test is the responsibility of the user. Special WARNING should be given to testing elderly subjects, children and handicapped people.
The device should never be used when it is possible or probable that the validity of the results may be compromised due to any such external factors.
WARNING
The instrument must be used as described in the User‟s Manual with particular
WARNING to the paragraph on Intended Use utilizing only original spare parts and accessories as specified by the manufacturer may be used. Use of non original parts such as the turbine sensor or other accessories may cause errors in measurement and/or compromise the correct functioning of the device. Any
spirolab

1.2.1 Danger of cross-contamination
Two different types of turbine sensors can be used with the device, one is reusable and one is single-patient disposable. A mouthpiece is required in order to connect a subject to the spirometer. In order to avoid exposing the subject to the critical danger of crosscontamination, the reusable flow sensor must always be cleaned before each spirometry test, and always use a new disposable mouthpiece for each subject. The use of an anti bacterial filter is at the discretion of the doctor. If a single-patient disposable turbine is used, then a new one must be used for each patient.
1.2.2 Turbine
WARNING
Disposable
Turbine
If you are going to perform the spirometry test with a
“disposable” turbine it is of vital importance to use a new turbine for each patient. The characteristics, accuracy and the hygiene of the disposable turbine can only be guaranteed if it has been conserved beforehand in its original sealed packaging. The disposable turbine is made of plastic and its disposal after use must adhere to the local regulations and norms in force.
Reusable
Turbine
The correct functioning of the re-usable turbine can only be guaranteed if it has been cleaned in the correct manner and is free from foreign bodies, which could restrict its movement. If the turbine has not been cleaned sufficiently this could cause cross-contamination from one patient to another. Periodic cleaning should only be done when the instrument is for personal use and will only be used by one patient. The cleaning of the turbine should be performed according to the instructions contained in the User‟s Manual.
For cleaning operations see § MAINTENANCE AND CLEANING in this Manual.
The following information applies to both types of turbine:
The turbine must never be held under a jet of water or air and must never come into contact with high temperature fluids.
Do not allow dust or foreign bodies to enter the turbine sensor, in order to avoid incorrect functioning and possible damage. The presence of any impurities such as hair, sputum, threads etc. within the body of the turbine sensor may seriously compromise the accuracy of the measurements.
To avoid environmental contamination by cleaning waste products, the user must adhere to all relevant regulations.
1.2.3 Mouthpiece
spirolab
III – User Manual Code MIR 980067 REV 2.0 Page 11 / 74
Any disposable mouthpieces included with the device are supplied only as a guide to the correct type and dimensions of the mouthpiece required for this device, they are clean but not sterile.
To purchase appropriate mouthpieces, generally either paper or plastic, but in any case mono-use/disposable, we suggest that you contact your local distributor who supplied the spirometer.
WARNING
Use a bio-compatible mouthpiece to avoid any problems to the patient; unsuitable materials could cause a bad functioning of the instrument, and therefore the test results could be incorrect.
The user is responsible for obtaining the correct type of mouthpieces for the device. Those required are a standard type with an outside diameter of 30 mm, they are commonly used and in general easily procured.

III. Use of other types of sensors may cause inaccurate readings.
Oximetry measurements may be inaccurate in the presence of high ambient light.
Shield the sensor area (with a surgical towel, for example) if necessary.
WARNING
Dyes introduced into the bloodstream, such as methylene blue, indocyanine green, indigo carmine, patent blue V (PBV), and fluorescein may adversely affect the accuracy of the oximetry reading.
Any condition that restricts blood flow, such as the use of a blood pressure cuff or a device for systemic vascular resistance, may cause an inability to determine accurate pulse rate and SpO2 readings.
Remove fingernail polish and/or false fingernails before applying SpO2 sensors.
Both may cause inaccurate oximetry measurement.
Significant levels of dysfunctional hemoglobins, such as carboxyhemoglobin or methemoglobin, may adversely affect the accuracy of the oximetry measurement.
Optical cross-talk can occur when two or more sensors are placed in close proximity. Optical cross-talk may adversely affect the accuracy of the oximetry readings. The danger can be eliminated by covering each site with opaque material.
Obstructions or dirt on the sensor‟s emitter and/or detector may cause a sensor failure or inaccurate readings. Make sure there are no obstructions and that the sensor is clean.
Autoclaving and/or ethylene oxide sterilizing may cause sensor damage. Do not attempt to sterilize the sensor.
Unplug the sensor from SpirolabIII before cleaning or disinfecting, to prevent damaging the sensor or the device and to prevent safety hazards for the user.
Do not use the instrument in the presence of magnetic resonance imaging (MRI) equipment. MRI equipment may cause an induced current to the oximetry sensor, resulting in patient injury.

2 PRODUCT DESCRIPTION
Spirolab
III is a spirometer with an optional pulse oximetry module that facilitates the total valuation of lung function. It is a powerful and compact measurement device intended for use by a physician (respiratory specialist), and which is capable of calculating more than
30 spirometric parameters.
Spirolab
III is able to make FVC, VC, IVC, MVV and breathing profile tests, as well as the saturation of oxygen in the blood and the heart beat.
It can operate in stand alone mode, and it can be connected to a PC or to a printer using any one of several available methods: RS232, USB, Bluetooth.
It calculates an index of test acceptability (test quality control) and a measure of reproducibility; It also gives functional interpretation with 11 possible levels following the latest ATS (American Thoracic Society) classification; it has an internal memory sufficient for over 6000 spirometry tests or for 1000 hours (or 40 days) of oximetry monitoring.
The main spirometric parameters are measured and displayed and all data with
Flow/Volume and Volume/time curves can be printed out in seconds by the built-in thermal printer. The Flow/Volume curve is shown in real time on the display.
Each test can be repeated as required. The best parameters are always available for quick viewing or printing. The normal (predicted) values can be selected from five different authors. In general, within the European Union the ERS (European Respiratory Society) predicted values are used.
The device also calculates the response to drug administration, i.e., the percentage change between spirometry results obtained before and after the subject takes a drug) and the results of a bronchial challenge test or a bronchodilation test. A comparison of data is made between POST (after-drug) and PRE (before drug administration).
The flow and volume measurement sensor is a digital turbine, based on the infrared interruption principal. This principal ensures the accuracy and the reproducibility of the measurements without requiring a periodic calibration.
The main features of this kind of sensor are listed below:
Accurate measurement even at very low flow rates (end of expiration)
Not influenced by gas humidity nor density
Shockproof and unbreakable
Inexpensive to replace
The turbine flow measurement sensor is available both in reusable and in single-patient disposable versions.
REUSABLE TURBINE DISPOSABLE TURBINE
spirolab
III – User Manual Code MIR 980067 REV 2.0 Page 22 / 74
The following precautions must be observed to ensure that the characteristics of the turbine remain unaltered over time:
For the disposable turbine: must always be substituted between patients.
For the reusable turbine: always clean the turbine between patients, to ensure the maximum level of hygiene and safety for the patient.
For a correct interpretation of a spirometry test, the measured values must be compared either with the so-called normal or predicted values which are calculated from the anthropometric details of the patient or, alternatively, with the personal best values from the clinical history of the subject.
The personal best values can vary considerably from the predicted values, which are taken from “healthy” subjects.
Spirolab
III is supplied with an RS-232 optoisolated serial communication port, which guarantees excellent electrical protection (> 4 KV) both for the health care worker and for the subject, in compliance with the most strict European safety standards (EN 60601-1).
The Bluetooth connection system can be used to connect the device directly to a printer
(the Bluetooth system must be installed and enabled on the printer as well).
Spirolab
III can also be connected to a PC (or to another computerised system) to configure the system. All spirometric test results plus the related subject details stored inside the device can be transferred from the device to the PC and then viewed within the winspiroPRO PC software (Flow/volume curves, spirometry parameters, plus optional oximetry parameters).
The connection to the PC can be made in the following ways:
through the RS232 port or
through the USB port
The internal software (or firmware) of the device can be upgraded quickly and simply from a PC.
For upgrading the system consult the manufacturer or an authorized representative.
spirolab
III gives an automatic interpretation of each spirometry test carried out, and assigns a “traffic light” feedback (green, yellow or red) to each test or series of tests. The set up of the traffic light settings is made by the doctor responsible for the system configuration.
Oximetry function
The oximetry sensor has two light emitting diodes (LEDs), one emits in the visible spectrum and one infrared. Both lights then pass through the finger and are “read” by the receiver. As these lights pass through the finger, a proportion of the light is absorbed by the blood and by the soft tissue, in function of the concentration of heamoglobin. The quantity of light absorbed, at each frequency, depends on the degree of oxygenation of the haemoglobin inside the soft tissue.
This measurement principal ensures accuracy and reproducibility, without requiring regular calibration.
The oximetry sensor can be disinfected with isopropilic alcohol for more information see paragraph 4.3.
The operating battery is a 3.6V lithium battery.

Turbine calibration
WARNING
The turbine flow sensor does not require calibration but needs only regular cleaning. If a calibration must be made then the following guidelines must be carefully noted.
Only the reusable turbine can be calibrated.
NOTE
Each time a calibration is made, the new correction factor is algebraically added to the previous correction factors. Therefore, before making a new calibration, make sure to delete the actual calibration in use as described above.
For an accurate and reliable calibration the syringe volume must be at least 3 L.
spirolab
III – User Manual Code MIR 980067 REV 2.0 Page 30 / 74
To modify the calibration of the turbine based on the
FVC values (for the expiratory phase) and FIVC (for the inspiratory phase), measured during a test made with a calibration syringe.
From configuration menu choosing “turbine calibration”, on the display appears the following informations.
The values “FVC” and “FIVC” are retailed to the last calibration. The values under the “%COR” column indicate the actual correction. They are set on 0 for default.
WARNING
ATP stands for Ambient Temperature and Pressure which indicates that the measurement conditions are ambient temperature and pressure.
BTPS stands for Body Temperature and Pressure Saturated which represents a world standard reference condition for the measurement of spirometric parameters. All spirometric parameters are calculated at body temperature (37
°C) and pressure saturated.
In line with the publication "STANDARDISED LUNG FUNCTION TESTING" of the
European Respiratory Society (Vol 6, Supplement 16, March 1993), the air expired from the mouth is at a temperature of circa 33/34 °C.
The expired flow and volume, to be converted back to BTPS conditions (37 °C), must be increased by 2.6% - this is derived from the BTPS factor of 1.026 at a temperature of 33°C, which represents a correction of 2.6%. In practice the BTPS factor for the expired flow and volumes is therefore constant and equal to 1.026.
For the inspired volumes and flows, the BTPS factor depends instead upon the ambient temperature, as the inspired air is at ambient temperature.
For instance, at an ambient temperature of 20°C with relative humidity at 50%, the
BTPS factor is 1.102, a correction of +10.2%.
The correction of the inspired volumes and flows is made automatically, as the device has an internal temperature sensor; all parameters are thus reported at
BTPS.
To make the calibration:
1 - Insert the volume in cL of the calibration syringe in use (e.g. for a 3L syringe, insert 300 cL).
2 - Insert both the FVC and FIVC values, obtained by the measurement made with the calibration syringe, in the New FVC and New FIVC field. Use vertical scrolls to select the value to be modified (SIRIN, New FVC, New FIVC).
Use numeric keys to modify the parameter value selected.
If the calculated correction factors are acceptable (<20%), they are displayed beside the
New FVC and New FIVC parameters.
spirolab
III – User Manual Code MIR 980067 REV 2.0 Page 31 / 74
Press ESC to return to the configuration Menu without entering the correction.
If the FVC and FIVC values produce a correction factor that is >20%, the FVC and FIVC values will not be accepted. This means that the system cannot correct for such a large calibration error. The following message appears:
WARNING ! ERROR too high
In this case:
- Check the correct functioning of the spirolab III with a new turbine and/or
- Clean the turbine.
To erase the calibration in use and reset to the factory calibration, input 0 in the New
FVC and New FIVC fields.
Then press to return to the Configuration Menu.
WARNING
With the new calibration, the correction factors are algebraically added to the previous correction factor(s).
Before to begin a new calibration set the two values FVC and FIVC at 0, then repeat the calibration procedure.
If a 3L syringe is used to make the calibration and if the spirometer is calibrated correctly then the FVC (syringe) value will be:
3.00 (FVC) x 1.026 (BTPS) = 3.08 L (FVC at BTPS).
If the ambient temperature is 20°C, the FIVC (syringe) value will be:
3.00 (FIVC) x 1.102 (BTPS) = 3.31 L (FIVC at BTPS).
The user must be aware that the volume of the syringe shown by the machine is converted to BTPS conditions, so that the "increase" of the results with respect to the expected values does not constitute an error.
For instance, if the calibration procedure is carried out with measured data:
20 ° C, FVC = 3.08, FIVC = 3.30 the spirometer is perfectly calibrated and the relative correction factors are null.
No calibration is required!
This does not represent an error, but is a logical consequence of the above detailed explanation.

The incentive is a hidden image, directly connected to the signal coming from the MiniFlowmeter so the harder the expiration then the further the “curtain” moves away, revealing the image and thus helping the patient to obtain the best possible result.
When the pediatric incentive is selected, a warning message is shown asking for the age of the patient. Set the correct value, the configuration menu is then shown.
Given that the FVC test requires collaboration that is difficult to obtain in children under the age of 4, then if an age of 4 or below is selected then spirolab III automatically shows the incentive during the FVC test.

2.5.6 Functioning of the spirometer spirolab
III performs the following measurements:
The valuation and interpretation of test results are given by comparing the measured parameters with specific
„normal‟ spirometry values (known as
Forced Vital Capacity
Slow Vital Capacity
Maximum Voluntary Ventilation predicted values) which are calculated
SpO2/BPM* from subject data: age, height, weight, sex and ethnic group.
* only for spirolab III with colour display
For the calculation of the predicted values, there are several different sets available both for adults and for children.

After each test session the results are compared to the selected predicted values and the percentage ratio between measured and predicted is shown for each parameter.
The test can be repeated more than once and the best result is memorized in order to be recalled from the spirolab III’s memory.
The best test result is determined following the ATS/ERS standards.
In practice, the best test is the one having the highest sum of FVC+FEV1.
All tests are analyzed by applying the quality criteria (quality control), following the ATS standards. In addition, the reproducibility of the FEV1, FVC and PEF parameters are also calculated.
It is possible to perform POST drug testing, in this case the test results are compared to a test made prior to the administration of drugs (PRE-test).

When a test is being performed the display will show the real time Flow/Volume curve or the Volume/time curve (if the pediatric incentive is set, then the volume/time curve is displayed.).
The test must begin within 30 seconds of pressing the start key, otherwise the test is interrupted and the device returns to the main screen.
2.6.1 Spirometry testing
Insert a new mouthpiece into the MiniFlowMeter mouthpiece holder.
Fit the nose clip onto the nose of the subject, to ensure that air cannot escape through the nostrils.
The subject must insert the mouthpiece well into the mouth, it should be inserted at least 2 cm beyond the front teeth and held between the teeth, closing the lips to ensure that air cannot escape from the sides of the mouth.
Breathe as directed according to the test to be undertaken, details follow.
Make the test in either a standing or a sitting position. During total expiration (slowly or forced) lean forward to help the expiratory action with a compression of the abdomen.
FVC
If required (this part is optional), before the test make several breaths at rest. When ready, inspire slowly as much air as possible (opening the arms helps) and then expire all of the air as fast as possible. Then, without removing the mouthpiece from the mouth, finish the test by inspiring again as fast and as completely as possible.
This final inspiration is not necessary in the case that the inspiratory parameters (FIVC,
FIV1, FIV1%, PIF) are not required.
The cycle can be repeated several times, without removing the mouthpiece, in which case
Spirolab
III will automatically select and show the best test and measured parameters. To end test press or just wait for 10 seconds after the last volume cycle, the test terminates automatically.

WARNING
In the case of an FVC test, after making at least two valid tests, the reproducibility of the parameters FVC, FEV1, and PEF is also shown.
VC/IVC and Ventilatory Profile tests
It is possible (optional) to begin the test by making several complete breaths at rest. After three or four similar breaths, a message (VC/IVC) on the display will indicate that the ventilatory profile has been measured and you can now proceed to carry out the VC or IVC test.
VC test: When the message VC/IVC appears, inspire slowly as much air as possible into the lungs and then expire slowly as much air as possible.
IVC test: When the message VC/IVC appears, expire slowly as much air as possible and then inspire slowly as much air as possible.
To end the test press or wait 3 seconds after the last volume cycle.
If you make the test without the ventilatory profile (respiratory function at rest) then the measured parameter will be only VC or IVC. Instead, by carrying out several complete breaths at rest, then in addition all measured parameters of the ventilatory profile will be given.
During the test the volume/time curve is displayed.
MVV
Start the test by carrying out a series of forced inspirations and expirations with the maximum possible amplitude. The suggested frequency is 30 breaths/min. The test will terminate automatically after 12 seconds.
To end test press or wait 3 seconds after the last volume cycle.
At the end of any test, the related curves and the main measured parameters are shown.

Whenever the test is repeated using the same dose, the best test related to the dose used is saved.
When the dose is changed, then a new record is made with a progressive FILE number.
For example, if three tests are made on a subject at different doses, then three different records (POST tests) are saved for that subject.
Afterwards the separate best POST tests can be viewed.
The subject code in the POST test is the same as for the related PRE test.
The results allow the confrontation of the spirometry parameters calculated in the POST test against the best results obtained in the PRE test already present in the patient archive for that session* (*session refers to tests carried out on that day). It is not possible therefore to carryout a POST test on a patient if the patient archive only contains PRE tests carried out only on previous days.
When the results are displayed it is possible to see the variation between the PRE and
POST values (shown in column headed CHG)
In the POST phase, the measured result is compared to the values of the related PRE test.
The Flow/Volume curves of the PRE test and related POST test are shown superimposed.
After the two curves, the measured parameters (POST), the related PRE values and the percentage variations between POST and PRE are also shown.

EST QUALITY CONTROL
-
SPIROMETRY
Through a mathematical analysis (quality control) which is applied to certain calculated indices and parameters, the spirolab III produces a series of comments, helpful for understanding the reliability of the test made.
This control quality check assigns a letter for the current session as described below:
PRE Test
A = At least two acceptable manoeuvres, with the highest two FEV1 values matching to within 100 mL and the largest two FEV6 values within 100 mL.
B= At least two acceptable manoeuvres, with the FEV1 values matching to within 101 to 150 mL
C= At least two acceptable manoeuvres, with FEV1 values matching to within 151 to
200 mL
D= only one acceptable manoeuvres, or more than one, but the FEV1 values not matching to within 200 mL (with no interpretation).
F= No acceptable manoeuvres (with no interpretation).
POST Test
A = two acceptable (1) FEV1 values matching within 100 mL
B= two acceptable (1) FEV1 values matching within 200 mL
C= two acceptable (1) FEV1 values that do not match within 200 mL
D= only one acceptable (1) FEV1 manoeuvre
F= No acceptable (1) FEV1 manoeuvres
Acceptable manoeuvre means: good start and satisfactory exhalation (duration and flow)
Where several comments related to the single test are calculated, spirolab III will only show the most important to facilitate the test interpretation.
ERROR IN Vext and PEFT
If the extrapolated volume Vext is greater than 500 mL or more than 5% of the FVC, or if the PEFT (time to peak flow) is greater than 200 ms, this message is shown:
Repeat test and blow faster
FET ERROR
If the FET is less than the minimum (3 seconds), this message is shown:
Expiry time insufficient
FLOW ERROR
If the last point of the F/V curve is greater than 200 mL/s, this indicates that the expiration was not complete and thus this message is shown:
Blow out all air in lungs

III – User Manual Code MIR 980067 REV 2.0 Page 45 / 74
2.9 R
EPEATABILITY OF THE FVC TEST
Following the international ATS and ERS standards, it is recommended to repeat each
FVC test at least 3 times to ensure the reliability of the spirometry test results. The device helps the user through the reproducibility control check.
Between tests, the repeatability of the following parameters is calculated:
PEF
VC repeatable when the difference between the two largest PEF is ≤ 0.67 L/s; repeatable when the difference between the two largest VC is ≤ 150 mL;
If FVC is > 1.0 L then:
FEV1
FVC repeatable when the difference between the two largest FEV1 is ≤ 150 mL; repeatable when the difference between the two largest FVC is ≤ 150 mL; if FVC is ≤ 1.0 L then:
FEV1
FVC repeatable when the difference between the two largest FEV1 is ≤ 100 mL; repeatable when the difference between the two largest FVC is ≤ 100 mL;
2.10 M
ETHOD OF MEASUREMENT AND INTERPRETATION
Spirometry test interpretation is based on the Forced Vital Capacity (FVC) test and is based on the ATS standard. For a faster comprehension this interpretation is illustrated by a traffic light code (green, yellow, red). For each test made, an arrow on the right of the screen indicates the worst level of interpretation of the test session.
The device uses the infrared interruption principle of measurement, with two sets of optoelectronic transmitters and receivers. A pair of deflectors positioned at the entry and at the exit of the turbine tube generates a vortex in the passing air, around the axis of the sensor. A rotor with a speed of rotation directly proportional to the air flow then interrupts the infrared beams and generates a digital signal. The measurement of the air volume that passes through the tube is proportional to the interruption of the infrared rays.
This measurement principle guarantees stability, reproducibility and reliability over a long period of time, and the measurement is not affected by gas density, humidity or pressure.
WARNING
The measurement of the air volume that passes through the tube is proportional to the interruption of the infrared rays.
The cleaning of the turbine flow sensor is very simple, and is essential for the protection of the subject from possible infections. For cleaning operations see Chapter 4 of this Manual.
No calibration of the turbine is required, but it is good practice to make a calibration check by following the simple instructions contained in the relevant paragraph in the maintenance section of this manual.
Method of test interpretation
Following each FVC test, the device carries out a quality control check to verify the acceptability of the test made and, if possible, compares the main measured parameters
FEV1, FEV1% and FVC with the respective predicted values. It also calculates a series of indices, based on the following criteria:
spirolab
III – User Manual Code MIR 980067 REV 2.0 Page 46 / 74
The interpretation of these indices %, according to the ATS standards, generates a series of messages which correspond to possible levels of obstruction or restriction plus one level of normal spirometry, as shown in the following table:
normal mild
green
green-yellow
yellow
yellow-red moderate moderately severe severe very severe
red violet
If it is not possible to make the calculations for lack of data, the interpretation is not valid and this message appears:
NOT VALID
WARNING
The interpretation during a test session for each subject always refers to the best test results made by that subject.

4 MAINTENANCE AND CLEANING
spirolab
III is an instrument that requires very limited maintenance. The operations to perform periodically are:
Cleaning and controlling of the reusable turbine.
Changing the disposable turbine at each test.
Cleaning of the oximetry sensor (for reusable sensors).
Changing the adhesive tape of the oximetry wrap sensor.
Changing the battery.
The maintenance operations described in the User‟s Manual must be carried out carefully.
Failing to observe the instructions may cause errors in measurement or in the interpretation of measured values.
Modifications, adjustments, repairs, and reconfiguration must be carried out by the manufacturer or by authorised persons.
In case problems arise, never attempt to repair the unit.
The setting of the configuration parameters must be carried out by qualified personnel. In any case, the risks from an incorrect setting do not constitute a danger for the patient.
The device is supplied with an internal lithium battery used to back-up the RAM; the average battery life is approximately 10 years. If this message appears:
WARNING ! Replace the internal lithium battery
Contact a service centre or the manufacturer for battery replacement.
4.1 C
LEANING THE DEVICE
Clean the device with a damp cloth. Make sure to dry it afterwards.
WARNING
Do not wet or immerse the device or power supply in any liquids.
Do not use any abrasive materials to clean the device.
4.2 C
LEANING THE REUSABLE TURBINE
The turbine utilized with spirolab III is of one of two categories: disposable or reusable.
These guarantee precise measurements and have the advantage of requiring no periodic calibration. In order to maintain these characteristics, a simple cleaning is required prior to each use ( only for the reusable turbine).
Cleaning of the disposable turbine is not required as it is supplied already clean in a sealed plastic bag. It must be disposed of after use.
The maintenance operations to perform are cleaning and controlling of the turbine.
spirolab
III – User Manual Code MIR 980067 REV 2.0 Page 60 / 74
WARNING
It is good practice to control from time to time that dirt or foreign bodies such as threads or hair are not deposited inside the turbine. Any such deposit could brake or block the blade of the turbine and thus compromise the measurement accuracy.
To clean the reusable turbine, remove it from its compartment in the MiniFlowmeter by turning it anti-clockwise and pressing lightly. It can be helpful to push it gently from underneath with one finger.
Immerse the turbine in a cold detergent solution and move it within the liquid to remove any impurities which may be deposited inside. Leave the turbine immersed for the time specified in the instructions of the solution.
WARNING
Miniflowmeter Turbine Mouthpiece
To avoid any kind of damage to the reusable turbine please do not use any alcoholic or oily substances, do not immerge the turbine in hot water or hot solution.
Do not put the turbine under a direct jet of water or other liquid. If no detergent solution is available, clean the turbine in clean water.
MIR suggest the use of Perasafe, manufactured by Dupont, which has been tested with positive results on all MIR sensors.
Rinse the turbine by immerging it in clean water ( not hot).
Shake off the excess water from the turbine and leave it to dry, standing it vertically on a dry surface.
To ensure that the turbine is functioning correctly before replacing it inside the instrument it is good practice to make a visual check of the rotation blade. Placing the turbine tube horizontally and moving it gently from left to right and vice versa, the rotation blade (rotor) must rotate freely. Otherwise, accurate measurement is no longer guaranteed, so the turbine must be replaced.
Once the turbine has been cleaned, insert the turbine tube in its place following the instructions indicated by the “lock “ symbol printed on the MiniFlowmeter.
To insert the turbine correctly, push it and then turn it clockwise until reaching the stop, which ensures that the tube has been blocked inside the casing.
Verify the free movement of the turbine:
Switch on spirolab III as if to make a spirometry test (for example FVC).
Hold the MiniFlowmeter in one hand and move it gently from side to side, so that air passes through the turbine.
spirolab
III – User Manual Code MIR 980067 REV 2.0 Page 61 / 74
If the rotor within the turbine is turning correctly, then you will hear a beep that indicates that the turbine is moving within the specific low flow range.
If moving the turbine from side to side at a constant velocity, regular beeps or no beeps at all are heard, then proceed with the cleaning of the turbine.
WARNING
If the disposable turbine is used, do not clean it but replace it after each test.
To avoid environmental contamination caused by the disposal of the cleaning solutions, the user must follow all local regulations.
4.3 C
LEANING AND DISINFECTION OF THE OXIMETRY SENSOR
WARNING
Do not sterilize by irradiation, steam, or, ethylene oxide. Do not immerse in liquids.
Before cleaning or disinfecting the sensor, unplug it from the device.
Clean the sensor with a soft cloth moistened with water or a mild soap solution. To disinfect the sensor, rub with isopropylic alcohol. Allow the sensor to dry completely after cleaning.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
