Asthma Peak Flow
Table of Contents
What is Peak Flow Measurement?
During a peak flow test, the physician is measuring the amount of air coming out of the lungs, also known as the peak expiratory flow rate. This can not only show the amount of air coming out of the lungs, but also the rate at that air can be breathed out from the lungs.
Why Use a Peak Flow Meter?
A peak flow meter can help determine at which stage to get emergency help, or when to stop and add medicines. All of this information should be written down on your asthma action plan.
How Do I use the Peak Flow Meter?
During the test, your physician will give you a mouthpiece from the device. The device is small and can be used anywhere. You will insert the mouthpiece into your mouth and breathe out as instructed. This should be done after a full lung inhalation.
