WebMar 1, 2014 · Step 1: Determine If the FEV1/FVC Ratio Is Low. The first step when interpreting PFT results is to determine if the forced expiratory volume in one second/forced vital capacity (FEV 1 /FVC) ratio ... WebLoge(PEF)= 0.376 x loge(age) - 0.0120 x (age) - 58.8/(height) + 5.63. The paediatric calculation (for ages below 15 years) is taken from Lung Function by J E Coates (Fourth Edition): PEF = 455 x (height/100)-332. In 2004 the Department of Health initiated a change to PEF meters to align to those that met a new EC standard. The new scale ...

After the starting point the curve rapidly mounts to a peak: Peak (Expiratory) Flow. After the PEF the curve descends (=the flow decreases) as more air is expired. stannah lift services andover
