WebPEF%P, MEF 50 %P, MEF 25 %P and PIF were significantly lower in COPD compared with BA. On the other hand, the I / E max ratio and PIF/MEF 50 were significantly higher in COPD than in BA. ROC curve analyses were performed using parameters which showed significant differences between COPD and BA. WebIntroduction. Both percentages of predicted forced expiratory volume in 1 second (FEV 1) and peak expiratory flow rate (PEFR) are widely used to estimate the degree of pulmonary impairment in patients with COPD. 1–3 In general, FEV 1 measurements by spirometry are preferred as it is much more reproducible. 4 However, spirometry is not widely available, …
WebMay 11, 2016 · Peak expiratory flow (PEF) and spirometry are the two most commonly used lung function tests in the diagnosis and monitoring of respiratory conditions. Both tests measure the speed and efficiency with which air moves in and out of the lungs. Conditions affecting airflow are called airway diseases and include asthma, chronic obstructive ...
