"It is a misconception that asthma conditions limit the amount of air a patient is able to take in or the capacity of the lungs. Instead it limits the amount of air that their lungs let out. Asthma subjects can take air in but have difficulty letting the air out. A PEF meter measures the pulmonary function of an individual by the maximum flow rate of air forcibly exhaled in one breath amount of air."
