Webheight were: PEFR= Height×3.64 -233.3 (for boys) PEFR= Height×2.91 - 103 (for girls). In both male and female children, PEFR significantly increases (p< 0.05) with height, weight, age. Conclusion: PEFR is a reliable measurement, which can be used in areas of Western Maharashtra for assessment of airway obstruction. WebMeasurement of PEFR requires training to correctly use a meter and the normal expected value depends on the patient's sex, age, and height. It is classically reduced in obstructive lung disorders such as asthma. Due to …

WebHeight – tall individuals tend to have a higher PERF. The calculator allows input in either cm or inches, however, inches are transformed in cm that are used in the formula. Peak expiratory flow rate (PEFR) is estimated via one of these equations: Children PEFR = ( (Height in cm - 100) x 5) + 100 WebPeak Expiratory Flow (PEF), likewise called Peak Expiratory Flow Rate (PEFR) is an individual’s maximum speed of expiration, as measured with a peak flow meter.

WebPeak expiratory flow rate (PEFR) was measured with mini Wright's peak flow meter in 783 children (aged 6-17 years) from a school in urban Delhi and 523 children (aged 6-15 years) from another school in Nellore, Andhra Pradesh. WebFor males: PEFR = (1.34 × height) + (1.41 × weight) + (16.56 × age) – 137.88, R-squared (R2) =0.751, P<0.001. For females: PEFR = (1.31 × height) + (0.94 × weight) + (7.30 × age) – 55.27, R-squared (R2) =0.507, P<0.001. Integration of age, height and weight for regression equation reported a significant coefficient than individual factor.

Malik et al,11 when relating peak expiratory flow rate (PEFR) to physical characteristics in normal adults, used a polynomial of third degree in age with height. These ... WebFormula for prediction of PEFR was estimated by linear regression analysis after the correlation of PEFR with age and height for both boys and girls. Results: PEFR was measured in 1028 children aged 5 to 16 years by using Wright's mini peak flow meter. Prediction equations were derived for PEFR with height in boys and girls.
