Flow volume curve: A diagnostic tool in extrathoracic airway obstruction
Abstract
The flow-volume loop (F/V-loop) is a presentation of inhalation and exhalation of air stream volume during inspiration and expiration. It demonstrates the obstructive, restrictive and mixed pattern lung pathology. Flow-volume loop has been extensively used for evaluating the severity, progression and resolution of various causes of upper-airway conditions.
