A member asked:

How long does the peak expiratory flow rate take?

A doctor has provided 1 answer

Breif: A peak expiratory flow rate is a fairly simple test done, usually as part of a comprehensive pulmonary function test procedure. By itself, a few minutes as one usually is instructed to do several attempts and the best result or average results recorded. A full set of pft's may take 30 minutes to an hour depending on factors like patient cooperation, quality of equipment etc.
