Abstract: A peak flow meter is described with a body having a sample channel and at least one bypass channel. One of at least two flow range scales may be selected using a flow range selector to adjust the sensitivity of the peak flow meter. A flow range selection indicator provides visual reference as to which flow range scale has been selected. A peak flow calculator used in cooperation with zone indicators on the peak flow meter permits a user to customize the peak flow meter for that user's predicted personal best exhalation range.
