
Prerequisite
The temperature and humidity sensor measures the required data

automatically. However, check these values for plausibility. For example,
if the temperature and humidity sensor is too close to the fan on the back
of EasyOne Pro/LAB, the measured temperature and humidity can be
wrong.
If you choose to adjust the values indicated by the temperature and
humidity sensor, you must enter the environment temperature within 1°C
or 1.8°F accuracy for this test.
1 Tell the patient to breathe at rest.
2 Tell the patient to fully exhale.
3 Tell the patient to take the spirette into the mouth and to seal the lips
around the spirette.
 The patient must not block the opening with the tongue or teeth or bite
down excessively on the spirette.
4 Tell the patient to fully inhale and fully exhale repeatedly for an
uninterrupted period of at least 12 seconds.
5 Tell the patient to take the spirette out of the mouth and to breathe
normally again.
