Tracing of tidal breathing followed by an inspiratory maneuver to total lung capacity
(TLC) to record inspiratory capacity (IC).
Definition of IC
Inspiratory capacity (IC) is volume change recorded at the mouth when taking a
full inspiration with no hesitation, from a position of passive end-tidal expiration,
i.e. FRC, to a position of maximum inspiration, expressed in liters at BTPS. IC is an
indirect estimate of the degree of lung hyperinflation at rest, and is useful to assess
changes in FRC with pharmacological interventions and physical exercise.
