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.

Search Device

Select the required option with  and confirm with ; spirolab III begins to search for

Bluetooth active devices; when one or more active devices are found then a list is shown, select a device and push to define the device (with vertical scroll) as a printer or as a phone (use PRINTER or PHONE); select one of the two options and push , otherwise

Even if the list is empty, a search can be made for active devices as previously described.

Remote line Number

Enter the menu with then it is possible to insert the telephone number that spirolab III will use to connect to a Bluetooth telephone. Insert the required number using the numeric keyboard and then press .

Oximetry settings

This function permits the following kinds of setting up :

 reference values for Sp02 and BPM; if, during a test, these values go below the minimum or above the maximum values in the set up an acoustic alarm will ring to alert the user

 activation/disactivation of the acoustic alarm

 set the sampling time (2 or 4 seconds) of oximetry values during a test

The cursor at the beginning will rest on the minimum Sp02 value, use the numeric keys to select the desired value, then the cursor automatically pass to the next value; if a value

must not be modified press ; once the four values have been set up you can then, if required, activate or disactivate the acoustic alarm by pressing key 1 for OFF and key 2 for

ON. To confirm the selection press . Then is possible to set the sampling time: press key

2 to set 2 sec or press key 4 to set 4 sec. Pressing the configuration menu is displayed.

Incentive

spirolab

III has a pediatric incentive program which can be useful to help a child (or an older person) make a correct spirometry test. 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.

Turbine setup

Select the type of turbine to be used for testing, either single-patient disposable or reusable. To select the correct option, follow the steps as described previously selecting the required item and press v to change the option.
