Vital capacity (VC)

Vital capacity (VC) is the maximum amount of air a person can exhale after taking the deepest breath possible. It reflects the strength and health of the lungs and respiratory muscles. VC is important for assessing lung function and can be affected by lung diseases or conditions that restrict airflow. Essentially, it measures how much air your lungs can hold and empty out, providing valuable information about your respiratory system's capacity and efficiency.
