FVC

FVC, or Forced Vital Capacity, is a medical measurement that indicates the total amount of air a person can forcibly exhale after taking the deepest breath possible. It helps assess lung function and can identify breathing problems, such as those caused by asthma, COPD, or other respiratory conditions. During a test, you breathe in fully, then blow out as forcefully and completely as you can into a special device. The FVC value reflects the lung’s capacity to hold and expel air, providing important information about the strength and health of your lungs.
