Forced Vital Capacity (FVC) Test
KEY
1
For this test the patient must exhale as quickly as possible from the time of starting
the test.
Note: The FVC test employs the `Back extrapolation` method. If the
extrapolated volume is too large (>0.15 litres or 5% of FVC), then
a warning appears on the display
To carry out the test for Forced Vital Capacity (FVC), press key `1` and the
corresponding coordinate presentation appears on the display.
The patient must exhale as quickly as possible from the time of starting the test so
be sure that he understands what is required of him. If inspiratory measurements
are required, the exhalation can be immediately followed by a maximum inhalation.
The inspiration results will be given on the printout.
The coordinates represent the graph on which the curve will be drawn with the
respiratory volume in litres being represented on the vertical axis and the time in
seconds on the horizontal axis.
