Introduction:

Forced expiratory maneuver can be defined as the clinical procedure that involves the voluntary efforts of a patient to expel air after a deep inhalation. This can be used for assessing the flow capacity of air in the lungs. The flow rate in the FVC (forced vital capacity) is both, effort dependent and effort independent.
