Please note: During the whole examination, the subject must not leave the
mouthpiece.
The Time Ex (expiration time) of the forced expiratory maneuver should last at
least:
- 3 seconds for patients <10 years
- 6 seconds for patients >= 10 years.
For visualiziation, a bar appears:
After 3 seconds (first bar for patients < 10 years) or 6 seconds (second bar for
patients >=10 years) of expiration, the filling color turns green and this test quality
criterion is fulfilled.
The EOT (End of Test) bar shows the change in volume in the last second. As
the bar shrinks and changes from red to green, the end of test quality criterion is
fulfilled.
The upper window shows the spirogram in volume-time display.
The lower window shows the flow-volume curve.
Start with <F2>.
The subject should breathe normally until stable tidal breathing is shown.
From tidal breathing, the subject is instructed to inhale as deeply as possible.
Without interruption, the subject should now immediately exhale as fast and as
much (FEV1) and as long (FVC) as possible. The maneuver is usually completed by
a maximal inhalation (VC IN) and continue to normal breathing.
