The mini-Wright expiratory peak flow meter.
The purpose of this study was to compare the recently modified mini-Wright peak flow meter with the Wright peak flow meter. One hundred adult patients were arbitrarily divided into two groups, based on their average peak flow on the mini-Wright device. A strong positive correlation in excess of 0.90 was shown. We believe that the smaller, cheaper device is as accurate as the Wright peak flow meter.
