Comparison 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 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 کاملHow to cheat with the miniature wright peak flow meter.
In February, 1982, Chest published an article concerning a new and innovative unit at Bethesda Medical Center in St. Paul, Minnesota. This unit is an Inpatient Service kr patients with chronic respiratory problems who cannot be maintained in a home setting. We have found, however, that with rehabilitation, education and appropriate support services, many of our patients could be discharged. Med...
متن کاملAn evaluation of the mini-Wright peak flow meter.
The mini-Wright peak flow meter (MPFM) has been evaluated, and the results obtained from it show a strong positive correlation (r=0.970) with the Wright's peak flow meter (PFM). MPFM measurements, however, were biased to be about 38 1/min higher than PFM measurements (95% confidence limits 31.01/min to 45.01/min). Between instrument variation was found (F--ratio 3.67 with 9 and 81 degrees of fr...
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 ...
