Peak Expiratory Flow Rate – A Consistent Marker of Respiratory …
WebPeak expiratory flow is estimated via one of the three formulas, depending on the patient characteristics: Children PEFR = ( (Height in cm - 100) x 5) + 100 Adult Men = ( ( (Height in m x 5.48) + 1.58) - (Age x 0.041)) x 60 Adult Women = ( ( (Height in m x 3.72) + 2.24) - (Age x 0.03)) x 60 Normal range in adults is between 390 and 740 L/min. WebPEFR is a valuable, useful, and easy-to-obtain parameter in asthma control and management. You can also use a peak flow chart to find your normal peak flow value. At … convert my thinkpad to dc

Webof PEFR prediction equations for use in African populations. [8,9] Of the few studies on PEFR prediction equations that have been conducted in African populations, some have assumed a linear relationship between PEFR and age, not taking account of the increase in lung function during adolescence before a subsequent decline in later life. A study in WebN2 - Peak expiratory flow rate (PEFR) measurement is the easiest and cheapest method to evaluate respiratory functions. So, the study was carried out to evaluate PEFR of healthy Nepalese adults and compare their values with healthy Indian counterparts to know whether Indian prediction equations for PEFR can be used for Nepalese adult population ...
