Definition: The amount of air which can be forcibly exhaled from the lungs after taking the deepest breath possible. Measuring FVC is done through spirometry testing which helps your doctor determine your lung function.
Because COPD causes the air in your lungs to be exhaled at a slower rate and in a smaller amounts compared to a normal, healthy person, measuring how well you can forcibly exhale air can help determine the presence of COPD.
Also Known As: FVC
