Peak Expiratory Flow Rate - Healthline

How is a peak expiratory flow rate test given? You’ll use a peak expiratory flow monitor to perform the PEFR test. This is a handheld instrument with a mouthpiece on one end and a scale on the other.

Peak Flow Measurement | Johns Hopkins Medicine Health Library

Peak flow measurement using a peak flow meter is useful for people with asthma. During an asthma flare-up, the large airways in the lungs slowly begin to narrow. This slows the speed of air moving through the lungs.

might be interested in the flow of energy, or in the flow ofmatter (e.g. of carbon). Most investigators try to analyze the flow of energy but because energy flow is difficult to measure directly, some uncertain conversions are nearlyalwaysincluded in thecalculations.Thus,it mightsometimesbebetter to restrict the conclusions to the mass flow.

Peak expiratory flow - Wikipedia

The peak expiratory flow (PEF), also called peak expiratory flow rate (PEFR) 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.

Measuring Your Peak Flow Rate | American Lung Association

Peak flow meters come in two ranges to measure the air pushed out of your lungs. A low-range peak flow meter is for small children, and a standard-range peak flow meter is for older children, teenagers and adults. An adult has much larger airways than a child and needs the larger range. There are several types of peak flow meters available.
