Explanation Justification for the correct answer: Option (b) is given as 30%. During the FVC (forced vital capacity) maneuver, the first 30% is dependent on the muscular effort by the individual, which arises from the large airways. Hence, option (b) is correct answer. Justification for the incorrect answers: Option (a) is given as 20%. This is false as around 30% of the forced expiratory maneuver is effort dependent...

Summary Introduction

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.
