VCin or IVC - Inspiratory Vital Capacity
The measurement starts with tidal breathing (establishing a stable baseline
mayrequire more than 5 tidal breaths). From tidal breathing the subject exhales
fully to residual volume (RV), followed by a full inspiration to total lung capacity
(TLC) and back to tidal breathing to record IVC or VCin.
The Time Ex (expiration time) of the maneuver should last at least 6 seconds.
For visualization, a bar appears which is slowly filled up in red color during
expiration. After 3 or 6 seconds of expiration (children or adult), 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.
Press <F7> to end the test and see the results.
The quality of the slow spirometry measurement depends on the subject’s
cooperation. In order to assess reproducibility (repeatability) and thus the quality
of cooperation, it is recommended to perform at least 3 trials.
Press <F1> to record another trial.
