Normal FEV1 values vary between individuals, and can depend on the following factors: age; gender; height; race

PNS. Peripheral but prevent normal respiration by reducing the oxygen level in the air. 8 nov. 2012 — PEth står för fosfatidyletanol och är en fosfolipid som inte förekommer i kroppen normalt sett utan bara bildas i närvaro av etanol. Detta gör den PEAK EXPIRATORY FLOW RATE - NORMAL VALUES For use with EU/EN13826 scale PEF meters only Adapted by Clement Clarke for use with EN13826 / EU scale peak flow meters from Nunn AJ Gregg I, Br Med J 1989:298;1068 -70 In me n, readings up to 100 L/min lower than predicted are within normal limits. For women, the equivalent figure is 85 What is Normal PEF Range Peak 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.

Green Zone: 80 to 100 percent of the usual or normal peak flow readings are clear. A peak flow reading in the green zone indicates that the lung function management is under good control. Yellow Zone: 50 to 79 percent of the usual or normal peak flow readings indicates caution. In normal males the range of PEFR lies between 450 and 700 liters per minute (L/min.). Normal females have a lower range between 300 and 500 L/min (4). It is lower in children than in adults.

2 maj 2011 — The method described in EN 15603 [2] is rather general l and provides PEF values for 13 energy carriers and chains. This is based on average

PEF är ett mått på det maximala utandningsflödet och mäts i liter/minut [6,11,12,17,26]. Vid mätningen används en så kallad peak-flowmätare (PEF-mätare).

HF-pEF. 1999-05-01 Objective: International consensus guidelines suggest that in asthma and chronic obstructive pulmonary disease (COPD), measurements of FEV1 and PEF are equivalent in the assessment of the degree of airflow obstruction when expressed as the per cent of predicted values.

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.

Average ranges in the healthy population depend mainly on sex and age, with FEF25–75% shown in diagram at left. Values ranging from 50-60% and up to 130% of the average are considered normal. Predicted normal values for FEF can be calculated and depend on age, sex, height, mass and ethnicity as well as the research study that they are based on.
