What is Forced Vital Capacity (FVC)?

Forced Vital Capacity (FVC) is a measure of the maximum amount of air a person can exhale forcefully after taking a deep breath. It is often used in pulmonary function tests to assess lung function and diagnose respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), and restrictive lung diseases. FVC is an important indicator of overall lung health and can help healthcare providers monitor the progression of lung diseases and the effectiveness of treatments.
