INTRODUCTION
The spirometers series MIR009 are sold with the SpirolabIII trademark.
SpirolabIII is available with two different displays:
• Colour LCD display
• B/W LCD display
Unless otherwise specified, from this point onwards the term SpirolabIII is used to refer to both models.
1 GENERAL INFORMATION
1.1 INTENDED USE
1.1.1 User Category
SpirolabIII, spirometer + oximeter calculates a series of parameters relating to human respiratory function.
The product is therefore intended for use by a doctor or by a trained paramedic or technician, under the supervision of a
doctor.
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
attention on cleaning operations (cross-contamination risk), all require qualified personnel.
'
'
SpirolabIII
' '
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.
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 ambiental
conditions.
)
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 attention 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.

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 cross-contamination, 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

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.
SpirolabIII – User’s Manual Code MIR 980067 REV 0 Page 9 / 47
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
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.
! 6 D
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.
1.2.4 Oximetry sensor
The following oximetry sensors can be used with SpirolabIII :
• BCI 1300 adult sensor (disposable)
• BCI 1310 reusable sensor
• BCI 3026 wrap-around sensor for infants

2 PRODUCT DESCRIPTION
SpirolabIII 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.
SpirolabIII 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.
SpirolabIII – User’s Manual Code MIR 980067 REV 0 Page 16 / 47
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
SINGLE-PATIENT DISPOSABLE
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.
SpirolabIII 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).
SpirolabIII 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.
SpirolabIII 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.
The operating battery is a 3.6V lithium battery.

2.5.6 Functioning of the spirometer
SpirolabIII performs the following measurements:
Forced Vital Capacity
Slow Vital Capacity
Maximum Voluntary Ventilation
SpO2/BPM
The valuation and interpretation of test results are given by comparing the measured parameters with specific ‘normal’
spirometry values (known as predicted values) which are calculated from subject data: age, height, weight, sex and
ethnic group.
For the calculation of the predicted values, there are several different sets available both for adults and for children.
For adults ERS (European Respiratory Society)
“ Knudson
“ Morris/Bass
“ Multicentrico Barcellona
For children Knudson
“ Zapletal
SpirolabIII – User’s Manual Code MIR 980067 REV 0 Page 25 / 47
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.
Measured
% Predicted = Predicted x 100
The test can be repeated more than once and the best result is memorized in order to be recalled from the SpirolabII’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).
SpirolabIII displays and prints the Flow/Volume and the Volume/time curves superimposed, with PRE and POST
parameter comparison and percentage of change:
Value POST
% PRE = Value PRE x 100
After switching on the device, the main screen will show a summary of the current patient data.

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 SpirolabIII will automatically
select and show the best test and measured parameters.
To end test press or just wait for 3 seconds after the last volume cycle, the test terminates automatically.

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 possibile 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.
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.

When the POST phase is activated, the patient data are shown and “POST” appears on the upper left part of the
screen.
=3 8; ( ; ( ; ;
In the POST phase, having selected one of these three tests or , the administered drug dose must
be entered.
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.
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.
=3 # '
Physiological test (placebo)
It is common practise prior to a POST test to carry out a test using physiological solution in place of a drug, to examine
the subject’s response to such a stimulus.
If the subject is healthy then the reaction to a placebo is almost zero, but in the case of hypersensitivity even this
stimulus can have some effect.
In the physiological test the amount of the dose to enter is zero and it is still possible to compare the POST results with
those of the PRE test.
The POST phase will show a coloured string highlighting the words POST FILE No. and DOSE.
The POST test can be activated both from the subject file on the main screen and also from the test results (
or ). This makes passing to the POST test phase more simple.
When viewing a subject file, only the following keys can be used:
• keys;
• ID# key (to make a new spirometry test with the current subject’s data file);
• key (to make a POST test);
• (to print selected test);
• and display keys;
• key to go back to the Data Management Menu;
• (exit key);
• No. 1, 2, 3 keys (in the event that one or more tests have been carried out).
2.7 TEST QUALITY CONTROL - SPIROMETRY
Through a mathematical analysis (quality control) which is applied to certain calculated indices and parameters, the
SpirolabIII produces a series of comments, helpful for understanding the reliability of the test made.
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:
SpirolabIII – User’s Manual Code MIR 980067 REV 0 Page 29 / 47
!"#$
FLOW DROP 50%
If the flow rate falls (>50%) and then rises again during the 1st second of a forced expiry, this message is shown:
%& '()*&)
FET ERROR
If the FET is less than the minimum (3 seconds), this message is shown:
+&&,&($$&'&
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:
"#(""&&"()
2.8 REPRODUCIBILITY 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 reproducibility of the following parameters is calculated:
FVC reproducible if FVC < 5 % or < 200 mL
FEV1 reproducible if FEV1 < 5 % or < 100 mL
PEF reproducible if PEF < 10 %
(delta) indicates the difference between two measured values.
At the end of an FVC test, the reproducibility of a single parameter is indicated alongside the numerical value by a +
sign (reproducible) or a - sign (not reproducible).
An FVC test is defined as reproducible when you have the reproducibility (+) for at least the FVC and FEV1 parameters.
2.9 METHOD OF MEASUREMENT AND INTERPRETATION
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.
The cleaning of the turbine flow sensor is very simple, and is essential for the protection of the subject from possible
infections. For cleaning and sterilizing 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:
measured values
index %=
predicted values x 100
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 spirometry
Possible very mild restriction/obstruction
Possible mild restriction/obstruction
Possible moderately severe restriction/obstruction
Possible severe restriction/obstruction
Possible very severe restriction/obstruction
Light green
Dark green
Light yellow
Dark yellow
Light red
Dark red
SpirolabIII – User’s Manual Code MIR 980067 REV 0 Page 30 / 47
If it is not possible to make the calculations for lack of data, the interpretation is not valid and this message appears:
• Not Valid

4 MAINTENANCE AND CLEANING
SpirolabIII 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 CLEANING THE DEVICE
Clean the device with a damp cloth. Make sure to dry it afterwards.

4.2 CLEANING THE REUSABLE TURBINE
The turbine utilized with SpirolabIII 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). This operation also ensures perfect
hygiene and thus the highest possible safety conditions for patients.
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.
%%
Miniflowmeter Turbine Mouthpiece
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 sterilising liquid and move it within the liquid to remove any impurities which may be
deposited inside. Leave it to soak for at least the time recommended by the producer of the cleaning solution, as shown
in the instructions (in general at least 20 minutes).
> ' #
< '
0 *'
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 SpirolabIII 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.
• 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.

the following symbol:
NOTE 1 At 80 MHz and 800 MHz, 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.
a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and
land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which
the Spirolab III is used exceeds the applicable RF compliance level above, the Spirolab III should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the Spirolab III.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [3] V/m.
