Peak flow measurement is a quick test to measure air flowing in and out of the lungs. Peak flow measurement is mostly done by people who have asthma.

Also see Pulmonary Function Testing. The most important and readily available test to evaluate the severity of an asthma attack is the measurement of peak

These include daily variability, minimum compared to maximum PEF over a 7-day period, difference between maximum and minimum PEF expressed as a percentage of maximum, or minimum morning PEF before bronchodilator use expressed as a percentage of the 7-day maximum or of predicted. 5,6,15 The aim of the present study was to determine whether PEF variability as defined in asthma management

ABSTRACT: Airway responsiveness and variability in peak expiratory ﬂow (PEF) are widely used as objective diagnostic measures of asthma, but it is not clear how these The diagnosis of asthma is supported if there is excessive variability in twice-daily PEFR over 2 weeks. In adults, an average daily diurnal variability in PEFR of >10% is considered excessive. An increase in PEFR by >20% from baseline after 4 weeks of treatment also indicates excessive variability.

Monitoring peak flow is most useful at key times. For example, if you’re recovering from an asthma attack, or your treatment plan has changed. You may be asked to keep a peak flow diary for a couple of weeks to help your GP confirm an asthma diagnosis.

PEF variability was determined using a portable mini-Wright peak flow meter (Clement Clarke International, London, UK; range, 50 L/min-800 L/min) over a 14-day period, with no changes in normal treatment.

An increase in PEFR by >20% from baseline after 4 weeks of treatment also indicates excessive variability.
