Vital capacity and COPD: the Swedish CArdioPulmonaryFVC, or Forced Vital Capacity, refers to the total amount of air that a person can exhale.
Forced Vital Capacity - University of Texas Medical BranchFVC is a measurement of the greatest amount of air you can forcefully breathe out after breathing in as deeply as you can.
