WebPredicted average PEF [L/min] = (Body height [cm] x 5.3) – 433 For example, if a child’s body height is 157 cm, the predicted average PEF (in L/min) is: 157 x 5.3 – 433 = 832.1 – 433 = …
WebPeak flow is a measure of how quickly you can blow air out of your lungs. If you have asthma, you may sometimes have narrow airways. This will make it more difficult to blow the air out of your lungs quickly and can change your peak flow score. WebForced expiratory volume in one second (FEV 1 ) is the most widely used measure for monitoring lung function decline. The following calculation enables a user to assess whether a decline in FEV 1 is excessive. The user should be familiar with spirometry basics . For computerized spirometry, we recommend using SPIROLA software.
WebPeak 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. This is a small, hand-held device utilized to keep an eye on a person’s ability to breathe out air.
