Peak flow meter. A peak flow meter, or spirometer, is used to monitor lung function by measuring the maximum rate at which air is expelled from the lungs. The patient takes a deep breath and breathes out as hard as possible into the mouthpiece (bottom). This test can be used to detect asthma and other lung disorders. | |
