Peak flow meter (made in USA) Peak flow readings are higher when patients are well, and lower when the airways are constricted. From changes in recorded values, patients and doctors may determine lung functionality, the severity of asthma symptoms, and treatment.
Normal values for peak expiratory flow (PEF), shown on EU scale. [21] Peak expiratory flow (PEF) is the maximal flow (or speed) achieved during the maximally forced expiration initiated at full inspiration, measured in liters per minute or in liters per second.
In obstructive lung disease, the FEV1 is reduced due to an obstruction of air escaping from the lungs. Thus, the FEV1/FVC ratio will be reduced. [4] More specifically, according to the National Institute for Clinical Excellence, the diagnosis of COPD is made when the FEV 1 /FVC ratio is less than 0.7 or [8] the FEV 1 is less than 75% of predicted; [9] however, other authoritative bodies have ...
For example, maximum inspiratory flow is denoted FIF max. Unless otherwise specified, volume qualifiers indicate the volume inspired from RV at the point of measurement.) PEF: Peak expiratory flow: The highest forced expiratory flow measured with a peak flow meter: MVV
