PEF is the highest expiratory flow obtained during a forced expiration starting immediately after a deep inspiration from total lung capacity. PEF is a simple, reproducible index and can be … Background: The primary lung function endpoint in clinical trials in adolescent and adult patients with asthma is usually forced expiratory volume in one second (FEV 1).The objective of our analysis was to assess whether peak expiratory flow (PEF) is a suitable alternative primary lung function endpoint.

Write down your peak flow number in your asthma diary every day. A decrease in peak flow of 20 to 30 percent of your personal best may mean the start of an asthma episode. Your Asthma Action Plan may tell you to take your peak flow reading more often and to adjust your medicines. Use only one meter. Be sure to bring it to your asthma check-ups.
