Checking Accuracy
All spirometry standards (e.g. ATS/ERS/BTS/ANZRS) recommend
checking the accuracy of lung function measuring devices at least daily
with a 3-L syringe to validate that the instrument is measuring
accurately. The Vitalograph In2itive should never be outside accuracy
limits unless damaged or in a fault condition. In this event, see the
fault-finding guide. In normal use, calibration traceability certification is
recommended as a part of the routine annual service.
ATS recommendations require that the difference between the volume
measured by the spirometer and the volume pumped into the
spirometer from a syringe is within 3%.
Follow these steps to check the accuracy of the unit.
1. Select Accuracy Check from the
Main Menu
using the keypad.
2. Enter the Syringe volume and reference using the touch panel
keypad.
3. Depending on how the device is configured you may be
prompted to enter the ambient temperature, humidity (0-99%),
pressure (25-31 inHg or 850-1060 hPa-mbar) and altitude (1-
8500m). Enter these values using the touch panel keypad.
4. Pump air through the flowhead to bring it to ambient
temperature.
If the flowhead has very recently been used for testing or has
come from a cold environment, its temperature should be
equilibrated with ambient by pumping air through it from the
syringe several times.
5. Press the ‘Enter’ key to bring you into the
Accuracy Check
screen and follow the on-screen instructions.
Note: Note: Press the ‘C’ key to exit the
Accuracy Check
screen
and return to the
Main Menu
. The accuracy check will not be
logged to the Vitalograph In2itive memory in this case.
6. If an Accuracy Check report is required select the Report option.
