What are your spirometry results based on?

ANSWER

Spirometry results are based on two measurements:

  • Forced vital capacity (FVC). This is the largest amount of air you can breathe out after breathing in as deeply as you can.
  • Forced expiratory volume (FEV-1). This  shows how much air you can exhale from your lungs in one second.
