FEV0.5%.
FEV0.5 as % of FVC.
FEV1%.
FEV1 as % of FVC. Same as FEV1/FVC. A parameter for a single FVC effort.
FEV1% formula.
A user-selectable formula that determines the calculation method for a test’s (not an
effort’s) overall FEV1% value, which affects the automatic interpretation.
FEV2%.
FEV2 as % of FVC.
FEV3%.
FEV3 as % of FVC.
FEV5%.
FEV5 as % of FVC.
FEV6%.
FEV6 as % of FVC.
FEVt.
Timed forced expiratory volume (in liters). Volume of air exhaled in the specified time during an FVC
effort.
FIF50.
Forced inspiratory flow (in L/s) at 50% of FIVC.
FIV1.
Forced inspiratory volume (in liters) at one second.
FIV1%.
FIV1 as % of FIVC.
FIVC.
Forced inspiratory vital capacity (in liters). The maximum volume of air that can be inspired during
forced inspiration starting from full expiration.
FIVt.
Timed forced inspiratory volume (in liters). Volume of air inhaled in the specified time (t).
flow.
The speed at which air is inhaled or exhaled (in L/s).
flow = f(v).
See
flow/volume.
Same as
flow over volume
or
flow = f(V)
. A type of data curve available during FVC testing.
The y axis represents flow (L/s); the x axis represents volume (liters).
flow loop.
A flow/volume curve that includes inspiratory data (negative values on the y axis).
FRC.
Functional residual capacity (in liters). Volume of air remaining in the lungs and airway at the average
end-expiratory level.
FVC.
Forced vital capacity. (1) A type of test in which patients inhale fully and exhale forcefully for as long
as they can. The goal: to measure the volume and flow of air. May or may not include forced inhaling.
When forced inhaling is included, it may be done either before or after exhaling. See also
(2) An important parameter (in liters): the maximum volume of air that can be delivered during forced
expiration starting from full inspiration.
IC.
Inspiratory capacity (in liters). The maximum volume of air that can be inhaled after a normal —
unforced — exhalation. See also
