The Estimated/Expected Peak Expiratory Flow (Peak Flow) quantifies asthma exacerbation severity.

Dec 2, 2021 · The following table summarizes the most common lung conditions and their PFT patterns. The cells in the table that are shaded yellow are the key findings that point toward each of these 4 conditions: When it comes to PFT interpretation, less is more.

The Normal value (Target value) for PEF differs according to gender, age and height. This chart can be used to read-off your Normal value. Enter this value in your “Target PEF.” information field. Peak flow readings are often categorized into 3 zones of measurement according to the American Lung Association; green, yellow, and red.

These peak expiratory flow (PEF) tables are averages and are based on tests with a large number of people. An individual's PEF may vary widely. Further, many individuals' PEF values are consistently higher or lower than the average values. It is recommended that PEF objectives for therapy be based upon each individual's "personal best," which is

This peak flow calculator allows you to calculate your normal peak expiratory flow (PEF), as well as your peak expiratory flow ratio (PEFR). The ratio is a relation between your measured PEF and the normal value, or, if you know it — your personal best.

The peak expiratory flow (PEF), also called peak expiratory flow rate (PEFR) and peak flow measurement, [1] is a person's maximum speed of expiration, as measured with a peak flow meter, a small, hand-held device used to monitor a person's ability to breathe out air.

For women, the equivalent figure is 85 L/min. Values are derived from Caucasian populations.

Predicted normal peak flow (PEF) values for women and men aged 15–85 years. Follow the chart line closest to your height to find the estimated normal PEF reading for a person corresponding to your age, gender, and height.

PEF is the maximum speed a person can blow air out of the lungs after taking as big a breath as possible. FEV1 is the maximum volume of air a person can exhale from the lungs in one second after taking as big a breath as possible.
