FVC (Forced Vital Capacity)

Forced Vital Capacity (FVC) is a measurement used in lung function tests to determine the total amount of air a person can forcibly exhale after taking a deep breath. It helps assess how well your lungs are working and can identify issues like blockages or restrictions. Typically, a healthcare provider asks you to breathe in deeply, then exhale as forcefully and completely as possible into a device. The FVC value provides important information about lung health and can help diagnose conditions such as asthma, COPD, or other respiratory problems.
