Normal measurement of peak expiratory Flow rate in the high school children in Babol, north of Iran
Background: Peak Expiratory Flow Rate (PEFR) is recommended as a tool for control of asthma. The purpose of this study was to determine the normal value of PEFR in the healthy high school children in Babol, Iran. Methods: This study was conducted on 470 healthy high school children (285 girls, 185 boys with the age between 14-18 years). For the determination of PEFR we used Mini Wright Peak Flo...
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...
متن کاملCalibration of some Wright peak flow meters.
The performance of Wright peak flow meters is described using an absolute and precise calibration method. This showed errors as great as 25% with the peak flow meter and 40% with the mini peak flow meter. At large flow rates errors were less. The expected variation between individual peak flow meters was about 12%. The expected variation between individual mini peak flow meters was between 16% ...
متن کاملPeak expiratory flow at altitude.
The mini Wright peak flow meter is a useful, portable instrument for field studies but being sensitive to air density will under-read at altitude. True peak expiratory flow will increase at altitude, however, because of the decreased air density, given that dynamic resistance is unchanged. The effect of simulated altitude on peak expiratory flow (PEF) was determined in six subjects with both th...
متن کاملPeak Expiratory Flow Rate in Healthy Children from Tehran
Background: Measuring peak expiratory flow rate has been suggested as an important tool in asthma management by all international guidelines. Objective: Studies on various populations have shown considerable variations in normal values of peak expiratory flow rate. Since reference standards for Iranian children are not available, the present study was performed to establish these standards. Me...
