Forced Vital Capacity (FVC) Test
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 liters or 5% of FVC),
then a warning appears on the display
To carry out the test for Forced Vital Capacity (FVC), highlight the `FVC` option in the test menu (previous page) and press the Enter key.
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 liters being represented on the
vertical axis and the time in seconds on the horizontal axis.
