Peak expiratory flow measurements indicated
WebMeasurement of peak expiratory flow gives an idea of how narrow or obstructed a person's airways are by measuring the maximum (or peak) rate at which they can blow air into a peak flow meter after a deep breath. Peak flow monitoring helps measure how much, and when, the airways are changing. WebForced expiratory volume (FEV). This is the amount of air expired during the first, second, and third seconds of the FVC test. Forced expiratory flow (FEF). This is the average rate …
