It is less used these days for the initial diagnosis of asthma, clinicians being encouraged to use more accurate measurements of lung function such as spirometry and the fractional exhaled nitrous oxide (FeNO) test.

Do not put your tongue in the hole. Blow out as hard and fast as you can In patients with asthma, the PEF percent predicted correlates reasonably well with the percent predicted value for the forced expiratory volume in one second (FEV 1) and provides an objective measure of airflow limitation when spirometry is not available [ 1,2 ]. PEF monitoring in patients with asthma will be reviewed here. A peak flow meter is a handheld device that measures how well air moves out of your lungs. During an asthma episode, your airways often narrow.
