A redesigned Peak Flow Whistle is described. It was evaluated and compared to the Wright Peak Flow Meter (WPFM) and the Vitalograph Pulmonary Monitor (VPM) using a laboratory flow system. These devices were evaluated for accuracy at steady flows, resistance characteristics, measurement of drift and dynamic accuracy. All devices tested correlated to a significant degree for accuracy at steady flows. The resistance of the WPFM and VPM increased with higher flows, whereas the Cardboard Peak Flow Whistle (CPFW) decreased. After pulsing the CPFW did not show any drift in calibration. The dynamic accuracy of the CPFW was excellent. Thus the accuracy of the CPFW and its lower cost makes it a practical device for measuring peak flows.

A peak flow (PF) measuring device, the Peak Flow Whistle (PFW), has recently been designed. The principle of a threshold activated reed is utilized to register PF, which differs significantly from the spring distortion mechanism utilized in currently marketed devices. Prototypes of the PFW were tested in the laboratory and in clinical settings as part of our preliminary studies. When compared with a pneumotachograph in the laboratory, the values correlated significantly (p less than .0001). In field studies both in asthmatic and non-asthmatic children, the PFW values correlated significantly (p less than .0001) with those of the Wright Peak Flow Meter and performance was found to be satisfactory.
