USING A PEAK FLOW METER TO TRACK ASTHMA

A peak flow meter is an easy-to-use handheld device that measures airflow in and out of the lungs. You can use a peak flow meter any time to see when you might have an asthma flareup. A peak flow meter is so sensitive it can tell that your airways are narrowing hours or even days before symptoms begin. By regularly measuring your airways, you can tell when an asthma attack is coming and preventively use asthma medications to limit or avoid symptoms or a serious episode. Tracking your asthma symptoms can also help you and your doctor see whether your medications are working, when to adjust medications and other treatments, and how to identify your asthma triggers.

P.S. A peak flow meter can measure changes in the airways more accurately than listening with a stethoscope.
