WebPeak expiratory flow (PEF), another PFT, assesses the maximal rate that air can quickly be expelled from the lungs. PEF is commonly used in primary care for diagnosis or assessment of COPD and asthma. PEF is not the first-line diagnostic tool for COPD or asthma due to more reliable measures with spirometry. WebPeak Expiratory Flow (PEF) s an objective measure of how well the lungs are functioning and can measure airway narrowing. A peak flow meter is a small device that measures the fastest rate of air that a person can blow out of their lungs.
