INTRODUCTION

Spirobank II
User manual

1.1 Intended use

Spirobank II spirometer and pulse oximeter is intended to be used by a physician, by a licensed healthcare professional or by a patient under the instruction of a physician or of a licensed healthcare professional. The device is intended to test lung function and can make:

· spirometry testing in adult and pediatric patients, excluding infants and neonates · oximetry testing in people of all ages.

It can be used in hospital setting, physician’s office, factory, pharmacy.

1.1.1 User category Spirobank II spirometer + oximeter calculates a series of parameters relating to human respiratory function. Typically the doctor “prescribes” a spirometry test and is responsible for analysing and checking the results obtained.

1.1.2 Ability and experience required
The correct use of the device, the interpretation of the results and the maintenance of the device all require qualified personnel. In the event that the device is to be operated by a patient, sufficient training must first be given to the patient by the doctor.

WARNING
The manufacturer cannot be held responsible for any damage caused by the user of the device failing to follow instructions and warnings in this manual. If the user of the device is a person considered to be cognitively impaired the operation of the device must be made under the supervision and responsibility of the person legally responsible to supervise the cognitively impaired person.

WARNING When used as a pulse-oximeter, the Spirobank II is intended for spot- checking, overnight sleep screening and/or continuous monitoring when used by a trained healthcare professional.
1.1.3 Operating Environment Spirobank II has been designed for use in the doctor’s office, in a hospital setting, physician’s office, factory, pharmacy
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 drafts (e.g. wind), sources of heat or cold, direct sunlight or other sources of light or energy, dust, sand or any chemical substances.
The user and/or doctor is responsible for ensuring that the device is stored and used in appropriate environmental conditions; in this regard reference is made to the specifications described in paragraph 1.6.3 below.
WARNING Exposure to unsuitable environmental conditions may cause the device to malfunction, and to provide incorrect results.
1.1.4 Patient effect on the use of the device
A spirometry test should only be carried out when the patient is at rest and in good health, in suitable testing conditions. A spirometry test requires the full collaboration of the patient since she/he must perform a complete forced expiration, in order to obtain a reliable test result.
1.1.5 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 patient’s clinical condition. A detailed clinical history of the patient is also required together with the results of any other test(s) suggested by a doctor. Test comments, a test interpretation and suggested therapeutic treatment must be given by a doctor. Any symptoms that the patient has at the time of the test must be carefully considered before a spirometry test is made. The user is responsible to assess both the mental and the physical condition of the patient in order to perform a proper test, furthermore, in the evaluation of test results, the user must also assess the degree of collaboration of each test carried out. A spirometry test requires the full collaboration of the patient. The results depend on the person’s ability to inspire as much air as possible and to expire all of the air as fast and for as long as possible. If these fundamental conditions are not respected then the results obtained during spirometry testing will not be considered accurate, and therefore the test results are “not acceptable”.

1.2.1 Danger of cross-contamination

Spirobank II
User manual

To avoid the danger of cross-contamination, a disposable mouthpiece must be used for each patient. The disposable turbine sensor must be replaced with each patient change. The instrument can use two types of turbine sensors: a reusable type and a disposable type. The reusable turbine sensor must be cleaned before using it on a new patient. The use of a viral antibacterial filter is left to the physician’s discretion.

1.2.2 Turbine

Disposable turbine
WARNING
If you decide to perform spirometry with the “disposable” turbine, it is essential to use a new turbine for each patient. The accuracy and hygiene characteristics and correct functioning of the disposable turbine are only guaranteed if it is kept intact in its original unopened packaging. The disposable turbine is made of plastic, and local regulations must be followed when disposing of it.

Reusable turbine
WARNING Proper functioning of the ‘reusable’ turbine is only guaranteed if it is ‘clean’ and free of foreign bodies that alter its movement. Insufficient cleaning of the reusable turbine can lead to cross-infection of the patient. Only and exclusively when the instrument is used for personal use, being used by the same patient, is periodic cleaning sufficient. For cleaning, please refer to the appropriate section in this user manual.
The following information applies to both types of turbine. The turbine must never be held under running water or direct air pressure and must never come into contact with hot fluids. Do not allow dust or foreign matter to enter the turbine sensor which may alter the correct functioning and possibly cause damage. The presence of any impurities such as hair, sputum, threads etc. within the body of the turbine sensor may seriously compromise measurement accuracy.
1.2.3 Mouthpiece
To purchase appropriate mouthpieces, generally either paper or plastic, single-use/disposable, we suggest that you contact your local distributor.

WARNING Use a bio-compatible mouthpiece to avoid any problems to the patient; unsuitable materials could cause the device to malfunction, consequently providing incorrect test results.
The user is responsible for obtaining the proper mouthpieces for the device. The required mouthpiece is a standard type with an outside diameter of 30 mm, is of common use and in general easily procured.

WARNING
To avoid environmental contamination caused by the disposal of used mouthpieces, the user must follow all the relevant local regulations.

Spirobank II
User manual
Prolonged use and/or the patient’s condition may require changing the sensor site periodically. Change sensor site and check skin integrity, blood circulation, and correct sensor alignment at least every 4 hours.
WARNING Incorrectly applied oximetry sensors or damaged cables may cause inaccurate readings. Using a damaged oximetry sensor may cause inaccurate readings, possibly resulting in patient injury or death. Inspect each oximetry sensor before use. If an oximetry sensor appears damaged, do not use it. Use another oximetry sensor or contact your authorized repair center for assistance. Use only MIR oximetry sensors supplied with, or specifically intended for use with Spirobank II. Use of oximetry sensors not intended for use with the Spirobank II 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 (for example; to perform a diagnostic tests) 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 the 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 measurements. 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 the sensor is clean. Autoclaving, ethylene oxide sterilizing, may cause sensor damage. Do not attempt to sterilize the sensor. Unplug the sensor from Spirobank II before cleaning or disinfecting to prevent damaging sensor or device, and to prevent safety hazards for the user.

1.2.5 USB connection cable
Incorrect use or application of the USB cable may produce inaccurate measurements, which will show very inaccurate values of the patient’s condition. Carefully inspect each cable before use. Do not use cables that appear to be or are damaged. If a new cable is required, contact your local distributor. Use only cables supplied by MIR, specifically designed to be used with Spirobank II. The use of other types of cables can lead to inaccurate measurements.

1.4.3 (ESD) Electrostatic discharge sensitivity symbol WARNING
Rev.2.4

Page 11 of 35

Spirobank II
User manual
Pins of connectors identified with the ESD warning symbol should not be touched and the connections should not be made to these connectors unless ESD precautionary procedures are used.

Precautionary procedures are the following:
· Environmental procedures as: air conditioning, humidification, conductive floor coverings, non-synthetic clothing · User procedures as: discharging one’s body to a large metal object, using wrist strap connected to earth.

It is recommended that all staff involved receive an explanation of the ESD warning symbol and training in ESD precautionary procedures.

the electrostatic discharge is defined as an electric charge at rest. It is the sudden flow of electricity between two objects caused by contact, an electrical short, or dielectric breakdown. ESD can be caused by a buildup of static electricity by tribocharging, or by electrostatic induction. At lower relative humidity, as the environment is drier, charge generation will increase significantly. Common plastics generally will create the greatest static charges. Typical electrostatic voltage values:

Walking across a carpet Walking over untreated vinyl floor Vinyl envelope used for work instructions Worker at a bench

1.500 ­ 35.000 volts 250 ­ 12.000 volts 600 ­ 7.000 volts 700 ­ 6.000 volts

If two items are at different electrostatic charge levels, as they approach one another, a spark or Electrostatic Discharge (ESD) can occur. This rapid, spontaneous transfer of electrostatic charge can generate heat and melt circuitry in electronic components. A latent defect can occur when an ESD sensitive item is exposed to an ESD event and is partially degraded. It may continue to perform its intended function, so may not be detected by normal inspection. Intermittent or permanent failures may occur at a later time. Static dissipative material will allow the transfer of charge to ground or to other conductive objects. The transfer of charge from a static dissipative material will generally take longer than from a conductive material of equivalent size. Some well known insulators are common plastics, and glass. An insulator will hold the charge and cannot be grounded and conduct. the charge away. Both conductors and insulators may become charged with static electricity and discharge. Grounding is a very effective ESD control tool, however, only conductors (conductive or dissipative) can be grounded. The fundamental ESD control principles are:

· Ground all conductors including people · Remove insulators, substitute with ESD protective versions · neutralize with ionizers · ESDS outside the EPA (ESD protected area) to be in packaging having ESD shielding property

1.5 Product description
The Spirobank II is a pocket spirometer, with an optional pulse oximetry module. It can operate either in stand-alone mode or it can be connected to a PC or to a printer using any one of several methods: USB, Bluetooth.

The device is specifically designed to measure a range of respiratory parameters and to monitor the saturation of oxygen in the blood and the heart beat. A quality control check is carried out internally on the measured parameters and the device has an internal memory sufficient for approximately 10.000 spirometry tests or at least 900 hours of oximetry monitoring.

Spirobank II is a powerful and compact measurement device, intended for use by a respiratory specialist or by a suitably trained general practitioner. The spirometer calculates up to 30 functional respiratory parameters providing the pharmacodynamic effects, i.e. the data comparison after the administration of a drug (PRE/POST) for a bronchodilator test or for a bronchial challenge 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 principle. This transducer ensures the accuracy and the reproducibility of the measurements, without requiring periodic calibration. The sensor features are listed below:

· Accurate measurement even at very low flow rates (end of expiration)
Rev.2.4

Page 12 of 35

· Not affected by relative humidity and air density · Shockproof and unbreakable · Inexpensive to replace.
The turbine flow measurement sensor is available both in reusable and in single-patient disposable versions.

· for the disposable turbine: must always be substituted from one patient to the other. · for the reusable turbine: always disinfect the turbine for testing from one patient to the next, to ensure the maximum level of hygiene
and safety.

For a correct interpretation of a spirometry test, the measured values must be compared either to the so-called normal or predicted values which are calculated from the anthropometric details of the patient or, alternatively, to 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.

Spirobank II can also be connected to a PC (or to another computerised system) to configure the instrument. All spirometry test data including the related patient details stored inside the device can be transferred from the device to the PC and then viewed on the PC (Flow/volume curves, spirometry parameters, plus optional oximetry parameters). The connection to the MIR Spiro can be made via USB connection.

Spirobank II can perform FVC, test, and calculates an index of test acceptability (quality control) plus the reproducibility of the spirometry tests carried out. Automatic functional interpretation involves the levels defined by the ATS (American Thoracic Society) classification. Each test can be repeated as required. The best parameters are always available for review. The normal (predicted) values can be selected from several normal “sets”. For example, within the European Union the majority of doctors use the ERS (European Respiratory Society) predicted values.

Oximetry function The oximetry sensor has two light emitting diodes (LEDs), one emits in the visible spectre 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 principle ensures accuracy and reproducibility, without requiring regular calibration. The oximetry sensor can be disinfected with isopropilic alcohol.

1.6.3 Oximetry alarms description
Spirobank II is equipped with audio and visual alarm indicators to alert the operator to provide prompt patient attention or to abnormal device conditions. Spirobank II detects both patient and equipment alarms. Both, patient alarms and equipment alarms are identified as medium priority as defined in IEC 60601-1-8 standard.

Medium Priority Alarms Medium priority alarms signal potential problems with the equipment or other non-life-threatening situations. Medium priority auditiry alarms are sounded as three beeps. The intended operator’s position for correctly perceiving a visual alarm signal is 1 meter.

Alarm Summary Spirobank II detects both patient and equipment alarms. Alarm indicators remain active for as long as the alarm condition is present.

WARNING Verify all alarm settings and limits before oximetry test starts to ensure that they are set as intended. Setting ALARM LIMITS to extreme values can render the ALARM SYSTEM useless. A hazard can exist if different presets are used on multiple devices in one care area.
Rev.2.4

Spirobank II
User manual

The alarm system provides medium priority alarm conditions for: – Low and high SpO2 level; – Low and high Pulse Rate level; – Sensor is unplugged; – Finger is not inserted – Low battery level.

Each alarm condition causes the generation of a visual alarm signal. The oximetry tests are intended not to be continuously attended by an operator in normal use, so additional auditory alarm signals are generated.

Patient (physiological) Alarms If patient SpO2 or pulse readings are equal to or above the upper alarm limit, or if they are equal to or below the lower alarm limit, the device will signal a medium priority alarm.

Equipment (technical) Alarms – Sensor is unplugged – Finger is not inserted – Low battery level

Visual Alarm Indicator When the alarm is activated through over limitation of physiological alarm, corresponding data area will view in reverse (video) mode. When the alarm is activated by more than one physiological alarm condition, each parameter will be displayed in reverse mode. If the alarm is triggered by a technical condition, the relevant warning message is displayed, for example:

WARNING FINGER is not inserted

Auditory Alarm Indicator Audible alarms can be heard in a quiet environment. The medium priority audible alarm has a “du-du-du” tone that repeats every 5 seconds. The acoustic alarm signal can be temporarily disabled while an alarm condition is in progress. The duration of the paused audio, the time interval in which the alarm system or part of the alarm system does not generate an audible alarm signal, is a maximum of 2 minutes. The sound pressure level of the alarm tone is about 55 dB, in complies with the standard.

Other beeps (acoustic signals): · Pulse tone, beeps at frequency depending on Pulse Rate · Sounds the next time the device is turned following an interrupted test due to low battery

The specifications that apply to SpO2 and Pulse Rate are the same regardless of the sensor used as long as it is one of those mentioned beforehand.

2.5.1 Reusable turbine calibration

WARNING
The reusable turbine does not need calibration, but only requires periodic cleaning. The reusable turbine is checked before being closed in the bag, so it does not need calibration. However, if you really want to carry out a calibration, bear the following in mind. The calibration operation can be performed on the reusable turbine as well as on the disposable turbine.

Spirobank II
User manual

Turbine calibration is performed with a calibration syringe to simulate a

FVC test for the expired parameters and a FIVC test for the inspired

parameters. To enter the calibration function, select the “Turbine Calibration” option

from the Service Menu (as explained in paragraph 2.5). To enter the new calibration values choose the item “Modify calibration” in the submenu,

enter the password and insert the new calibration values. Make three

manoeuvres with a sirynge as described by the screen on the device, then

Spirobank II calculates the FVC and FIVC values.

Press

.

The screen requires to insert the volume of the syringe in use; Spirobank II so calculates the correction percentage between the reference

and the calculated value. It can be possible to change the syringe volume using

and , then press . At this point two new

correction values are shown. Press to apply these correction, otherwise press

to set the factory calibration values (0%).

If the FVC and FIVC correction factors are > 10% the following message appears on the screen:

WARNING The calibration Is out of range
The FVC and FIVC values will not be accepted. This means that the device is not capable of correcting such a large calibration error In this case:
– Check the correct functioning of the Spirobank II with a new turbine and/or – Clean the turbine.
To erase the calibration in use and to reset the original factory calibration, use the item “Factory defaults” from the Calibration menu

WARNING
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 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 upon the ambient temperature as the air inspired 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 machine has an internal temperature sensor; the BTPS values are thus calculated. If a 3L syringe is used to make the calibration and if the Spirobank II 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:

Rev.2.4

Page 22 of 35

Spirobank II

User manual

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:

FVC = 3.08 L and FIVC = 3.31 L at an ambient temperature of 20°C the resulting correction factor becomes:

EXPIRATION

.00%

INSPIRATION

.00%

This does not represent an error, but is a logical consequence of the above detailed explanation.

When the device is connected to the table it can be only remotely controlled. The default settings of the tablet software will be transferred to the device and will remain in the device even when used in stand-alone mode, until the device is restarted.

2.9 Spirometry testing
In order to perform proper spirometry testing the following instructions are to be followed carefully.
· Insert the turbine in the appropriate housing until it reaches the mechanic stop and successively rotate the turbine clockwise until it stops. Insert the mouthpiece at least 0.5 cm inside the groove of the turbine.
· Place the noseclips on the nose so as not to let any air out of the patient’s nostrils. · Hold the Spirobank II with both hands or grasp it like a mobile phone. The display must always face the patient taking the test. · Place the upper part of the mouthpiece in the mouth making sure that no air leaks from the sides of the mouth.

WARNING
Correct positioning of the mouthpiece extending under the dental arch in the patient’s mouth is fundamental so as to avoid any turbulence which could erroneously affect the spirometry results.

WARNING
If possible it is recommended to stand up while performing the test. During expiration it is recommended to bend forward the upper part of the body so as to release all the air out with the aid of the abdominal muscles.

2.9.1 FVC test

Proper execution of a FVC test must take into account the phases as described on the screen, more specifically:
INSPIRE all the air EXPIRE fully with force INSPIRE fully with force
It is possible (and may be helpful) to start the test by breathing at rest for a few moments. When ready to start inspire slowly as much air as possible (made easier by raising the arms wide apart) and then make a complete expiration as fast as possible. Then with the mouthpiece always held firmly in the mouth, complete the cycle by inspiring again as quickly as possible. This final inspiration may be left out if the inspiratory parameters (FIVC, FIV1, FIV1%, PIF) are not of interest. The optional initial inspiration phase can also be performed before inserting the mouthpiece in the mouth. After inspiring slowly and deeply, the following expiration must be made with the maximum effort by expiring all the air in the lungs as fast as possible. After 6 seconds of expiration the device will emit a continuous beep, this helps the user to understand whether the minimum expiry time has been reached, as recommended by the main international respiratory institutions.

WARNING Accurate spirometry testing requires that the patient expire all the air in the lungs.

The test may be carried out several times by repeating the cycle without taking the mouthpiece out of the mouth, in which case Spirobank II recognises the best test (largest FVC+FEV1) and will automatically display the results of the best test.
To end the test press .

Rev.2.4

Spirobank II
User manual
During the test the Spirobank II emits “beeps”, the frequency of which are directly proportional to the inspired and expired velocity of the air. This helps the doctor understand when the velocity of the air is approaching zero, and the patient has almost exhausted all of the inspired or expired volume. In the maintenance section an explanation is given as to how this feature can also function as a very simple checking system for the correct operation of the mobile “rotor” of the turbine. For the FVC test to be judged as acceptable, besides breathing as deep as possible, it is also required that the forced expiratory time (FET) is sufficiently long to allow for the complete expiration of all air contained in the lungs.

2.9.2 POST test, after drug administration

WARNING
To carry out a POST test it is necessary to have carried out at least one PRE FVC test the same day; it is not possible to do a POST test on the PRE VC or MVV tests; it is however possible to do a POST VC or MVV test if the database already contains at least one PRE test carried out on the same day.

To carry out a POST test please access to the spirometry area pressing

and subsequently pressing .

A POST test is a spirometry test following the administration of a drug of some kind, usually a bronchodilator. The sign “POST Phase” is shown on the screen of the device (center) on the first screen of the spirometry area.. The following tests made by the patient show the following parameters:

· Those values related to the test performed · Those values related to the best PRE test performed by the same patient the same day.(that is in the same test session) · The percentage variation between the PRE and POST values (in the CHG column)

It is not possible to perform a POST test with a patient whose PRE testing was not carried out on the same day. If during a POST session a new patient is inserted or another is recalled from the archive the device will automatically exit the current POST session.
2.10 Viewing the spirometric results

Following a FVC test, the spirometry test results are shown. The first screen displays a Flow/Volume graph of the Forced Vital Capacity
pressing the parameters FVC, FEV1, FEV1%, PEF relative to the best acceptable in the session are displayed with the percentage ratio in relation to the theoretical values.

By scrolling with and it is possible to view all the parameters next to the chosen predicted values.

2.10.1 Acceptability, Repeatability and quality messages
Acceptability, usability, and repeatability of FVC and FEV1 parameters for each single test are defined as summarized in Table 7 of the ATS/ERS 2019 guideline:

For FEV1 and FVC
Acceptability and Usability Criterion Must have EVOL (VEXT or BEV) <5% of FVC or 0.100 L, whichever is greater Must have no cough in the first second of expiration Must have no glottic closure in the first second of expiration Must have no glottic closure after 1 second of expiration Must achieve one of these three end of forced expiration (EOFE) indicators: Expiratory plateau (<0.025 L in the last 1 second of expiration) Expiratory time >15 seconds FVC is within the repeatability tolerance of or is greater than the largest prior observed FVC Must have no evidence of obstructed mouthpiece or spirometer Must have no evidence of a leak If the maximal inspiration after EOFE is greater than FVC, then FIVC – FVC must be <0.100 L or 5% of FVC, whichever is greater

Required for Acceptability FEV1 FVC YES YES YES NO YES YES NO YES NO YES
YES YES YES YES YES YES

Required for Usability FEV1 FVC YES YES YES NO YES YES NO NO NO NO
NO NO NO NO NO NO

Repeatability criteria (applied to acceptable FVC and FEV1 values) Age > 6 years: The difference between the two largest FVC values must be <0.150 L, and the difference between the two largest FEV1 values must be <0.150 L

Rev.2.4

Age < 6 years: The difference between the two largest FVC values must be <0.100 L or 10% of the highest value, whichever is greater, and the difference between the two largest FEV1 values must be <0.100 L or 10% of the highest value, whichever is greater
Abbreviations: EVOL (VEXT o BEV) = back-extrapolated volume; EOFE = end of forced expiration; FEV075 = forced expiratory volume in the first 0.75 seconds. The grading system (above Table 10) will inform the interpreter if values are reported from usable maneuvers not meeting all acceptability criteria. *For children aged 6 years or younger, must have at least 0.75 seconds of expiration without glottic closure or cough for acceptable or usable measurement of FEV0.75. Occurs when the patient cannot expire long enough to achieve a plateau (e.g., children with high elastic recoil or patients with restrictive lung disease) or when the patient inspires or comes off the mouthpiece before a plateau. For withinmaneuver acceptability, the FVC must be greater than or within the repeatability tolerance of the largest FVC observed before this maneuver within the current prebronchodilator or the current post-bronchodilator testing set. Although the performance of a maximal forced inspiration is strongly recommended, its absence does not preclude a maneuver from being judged acceptable, unless extrathoracic obstruction is specifically being investigated. The design of MIR spirometers with turbine is such that they are not subject to faulty zero-flow setting.

For VC test the acceptability criteria according to ATS/ERS 2019 guideline is defined as follows: the VC test is considered acceptable is there is less than a 0.025 L volume increase over 1 second; in this case the test is deemed as having a plateau.

The Repeatability criteria in case of VC test is defined as follows:

Number of 3 acceptable tests are required

tests

VC

The difference in VC between the largest and next largest manoeuvre must be smaller of the following:

0.150 L or 10% VC, for patient older than 6 years of age

Or

0.100 L or 10% VC. For those aged 6 years or younger

Otherwise, additional trials should be performed.

After each maneuver, ATS/ERS 2019 guideline provides a quality messages based on acceptability criteria define in table 7 of ATS/ERS 2019 guideline, as follows:

Warning message No plateau Hesitant start Slow start Abrupt stop

after completely emptying your lungs, remember to breathe in – back to the top fill your lungs completely before blasting out ­ take the deepest breath possible

WARNING
The best test with the criteria defined in the 2019 ATS guideline is not considered the one with the best FVC+FEV1 sum, but is chosen among the tests that meet the acceptability criteria set by the aforementioned guideline. Then it is chosen among those tests that did not provide error messages The following table of the ATS 2019 guideline defines the criteria for choosing tests for acceptability and repeatability.

The repeatability grade is determined for the set of prebronchodilator maneuvers and the set of post-bronchodilator

maneuvers separately. The repeatability criteria are applied to the differences between the two largest FVC values and

the two largest FEV1 values. Grade U indicates that only usable but not acceptable measurements were obtained.

Although some maneuvers may be acceptable or usable at grading levels lower than A, the overriding goal must be

to always achieve the best possible testing quality for each patient. Adapted from Am. J. Respir. Crit. Care Med. 2017;196:1463­1472.

*Or 10% of the highest value, whichever is greater; applies for age 6 years or younger only

2.10.2 Interpreting spirometry results
The interpretation of spirometry refers to Forced Vital Capacity (FVC) and is seen by means of indicator lighting. This interpretation is calculated on the best manoeuvre according to the ATS /ERS 2019 guideline. The messages can include the following:
Normal spirometry Light obstruction/restriction Moderate obstruction/restriction Moderately severe obstruction/restriction Severe obstruction/restriction Very severe obstruction/restriction

The final interpretation level is “restriction + obstruction”, where the indicator light indicates the worst parameter between restriction and obstruction.

2.11 Oximetry Testing

WARNING Check if the oximetry function is available in the device, this function is an option in some models.

WARNING
The oximetry sensor used in the manual is only one of the different types of sensors which can be used listed in paragraph 2.2.4. MIR does not recommend any particular sensor; the doctor will chose the sensor which she/he believes to be more suitable.

During oximetry testing the Spirobank II cannot be turned off. To turn off the device the oximetry test must be stopped first. This has been implemented so as to avoid any unwanted interruptions which could compromise the accuracy of the data.

For the non-invasive measurement of SpO2 oxygen saturation and blood pulse rate, utilize the re-usable finger sensor. This sensor is recommended for patients weighing more than 20 Kg while remaining still during testing. For the 6 minute walk test other types of sensors are recommended which are less influenced by the movement of the hand.

To carry out an oximetry test: · Connect the sensor to the device: insert the connector with the arrow
(printed on the connector) face-up, as shown: · Choose a high perfusion site, easily adaptable to the sensor. · Insert the finger into the sensor until the finger touches the end of the
probe. Ensure that the bottom part of the finger completely covers the detector. If the finger cannot be placed properly inside the sensor try another finger. · Place the sensor so that the cable rests on the back of the hand. This ensures that the light source rests. On the side of the nail and the reader on the lower part of the hand. · Select one of the tests that can be performed with Spirobank II.

4.1 Cleaning and checking the reusable turbine

Spirobank II
User manual

Two types of turbines can be used with Spirobank II. The disposable turbine or the reusable turbine. Both guarantee precise measurements and have the advantage of requiring no periodic calibration. In order to maintain the default characteristics of the reusable turbine a simple cleaning procedure is required before use. Cleaning of the disposable turbine is not required, as it is supplied clean in a sealed plastic bag. It must be disposed of after use.

WARNING
Periodically check the inside of the turbine to ensure that there are no impurities, corpuscles, or any foreign matter like hairs which could inadvertently block or even slow down the mobile equipment in the turbine and as a consequence compromise spirometry measurement accuracy.
Before use perform the test described in paragraph 4.1.1 which allows to the check the efficiency of the turbine. If the test result is negative perform the following procedure. To clean the reusable turbine remove it from its housing by rotating it counter-clockwise and apply slight pressure with a finger from the bottom of the turbine to lift it out of its housing. Immerse the turbine in a cold liquid solution and shake it so as to remove any impurities. Leave the turbine immersed for the time specified in the instruction of the solution.

WARNING To avoid irreparable damage to the reusable turbine please do not use any alcoholic or oily detergent solutions, and do not immerge the turbine in hot water or hot liquids. Do not place the turbine under a direct water jet or other liquid. If no detergent solution is available, clean the turbine in clean water. Do not use compressed air to clean the turbine.
Rinse the turbine by immerging it in clean water (not hot). Shake off the excess water from the turbine and let it dry, position the turbine vertically on a dry surface.
Before inserting the reusable turbine in the device it is good practice to visually check that the rotor inside turns freely. Hold the turbine horizontally and slowly move it left and right and vice versa. You should be able to see the mobile equipment (blade) rotate freely. If this is not the case then the measurement accuracy can no longer be guaranteed and as such the turbine must be replaced.
Having completed the turbine cleaning procedure, insert the turbine in its housing making sure to turn it clockwise as shown by the symbol of the lock printed on Spirobank II.
The turbine is inserted properly by pushing it all the way in and subsequently rotating it clockwise until it stops; this bayonet mechanism ensures that the turbine is blocked inside the plastic casing.
To be absolutely certain that the turbine is functioning properly perform the checklist in paragraph 4.1.1; if the turbine is still malfunctioning please replace it with a new one.

WARNING Do not carry out any cleaning procedures when using disposable turbines, a new disposable turbine must be used for every new patient.
4.1.1 Proper turbine operation check
· Turn on Spirobank II · setup the device to perform a spirometry test (for example FVC). · Hold the Spirobank II with one hand and move it slowly sideways, having the air pass through the turbine. · If the rotor spins properly the device will emit a series of acoustic signals “beeps”. The beeping frequency is a function of the air
flow passing through the turbine. · If no beeps are heard while moving the device, proceed to clean the turbine

4.2 Cleaning of the device

Clean the device once a day or every time changes the patient. Use only the substances and methods listed in this chapter to clean the device. Recommended cleaning agents are:
· Mild soap (diluted) · Sodium hypochlorite bleach (10% diluted) · Hydrogen peroxide (1.5%)
