![]() ![]() This is a regular clinical event which means that a tidal volume inaccuracy of 10 shall be accepted and not be seen as a clinical risk. Learn more about when spirometry is needed, how it’s performed and understanding results.

Forced expiratory volume (FEV1): the amount of air you can exhale with force in 1 second.Forced vital capacity can decrease by about 0.2 liters per decade, even for healthy people who have never smoked. It is about 80 percent of total capacity, or 4.8 liters, because some air remains in your lungs after you exhale.
