Web17 de ago. de 2024 · Overview. Spirometry (spy-ROM-uh-tree) is a common office test used to assess how well your lungs work by measuring how much air you inhale, how much you exhale and how quickly you exhale. Spirometry is used to diagnose asthma, chronic obstructive pulmonary disease (COPD) and other conditions that affect breathing. WebThe peak expiratory flow (PEF) is the maximum flow obtained within the first 200 milliseconds of a forced expiratory maneuver after inhalation to total lung capacity (TLC). PEF meters are portable, inexpensive, and easily used. Peak flow monitoring in patients with known asthma is useful in monitoring disease activity and response to ...
