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.
