Hint: Close the opening of the pneumotach during zero adjustment with the
palm of your hand.
The volume signal must run horizontally after the measurement was started
(subject not yet breathing into device). If you observe curves going up or
down (see example) during a measurement, the pneumotach has not been
properly zeroed.
Make certain that the pneumotach is not moved and the subject is not
breathing through the mouthpiece.
In order to fix this, press <F7> “Result“ to enter the Result phase and then press
<F8> “Zero“ to start zero adjustment again.
Note:
Two vertical lines will automatically be set in the spirogram window indicating
the space to be filled by the breathing maneuver.
Depending on the study protocol one of the following maneuver needs to be
performed to record the parameters needed – please also see the protocol-
specific Short Guide.
