Comparison of peak flow gauge and peak flow meter.
A comparison has been made of the new peak flow gauge and the Wright peak flow meter. Close correlation was found between measurements made with the two instruments both in normal subjects and in patients. The peak flow gauge is as consistent as the peak flow meter but is cheaper and more portable. It should be useful in survey work in general practice and for loan from hospital outpatient depa...
متن کاملComparison of the new miniature Wright peak flow meter with the standard Wright peak flow meter.
Preproduction and current models of the miniature Wright peak flow meter have been compared with the standard Wright peak flow meter on normal and abnormal subjects. Early problems in production appear to have been overcome, and the current model agrees to within 3% with the standard peak flow meter, which is as close as the agreement between two standard instruments. The new mini-meter may be ...
متن کاملPeak expiratory flow and the resistance of the mini-wright peak flow meter.
The purpose of this study was to examine whether the resistance of the peak flow meter influences its recordings. One hundred and twelve subjects, (healthy nonsmokers and smokers and subjects with lung diseases) performed three or more peak expiratory flow (PEF) manoeuvres through a Fleisch pneumotachograph with and without a mini-Wright peak flow meter added in random order as a resistance in ...
متن کاملA miniature Wright peak-flow meter.
A new miniature Wright peak-flow meter has been designed and produced. The meter is tubular with a spring-loaded piston and a longitudinal slot through which air escapes. Its dynamic characteristics have been carefully designed to make it respond only to peak flow and not to rate of rise. Performance tests on early instruments showed fairly close correlation with the Wright peak-flow meter but ...
متن کاملMeasuring peak expiratory flow in general practice: comparison of mini Wright peak flow meter and turbine spirometer.
OBJECTIVE To compare measurements of the peak expiratory flow rate taken by the mini Wright peak flow meter and the turbine spirometer. DESIGN Pragmatic study with randomised order of use of recording instruments. Phase 1 compared a peak expiratory flow type expiration recorded by the mini Wright peak flow meter with an expiration to forced vital capacity recorded by the turbine spirometer. P...
