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 "Standardized 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:
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.
NOTE
A calibration may also be performed with the winspiroPRO software included with the device. For more information
concerning the on line calibration procedure using winspiroPRO please read the on line winspiroPRO manual
