The deceleration time is another simple means of evaluating the MV area, in which decay of the mitral inflow profile through a stenotic MV is examined. The following formula describes the relationship of the deceleration time to the MV area (19):
EXPIRATORY TIME. The time required for the subject to reach his largest volume (FVC). For quality control purposes, total expiratory time is the time from the beginning of exhalation to. the end of the subject=s expiratory maneuver.
