STRIVE Peak Flow Meter

People with asthma have problems when their airways constrict and tighten decreasing air flow through them. The small slim device is designed to fit in your pocket ready to go anywhere.

A peak flow meter is a device that measures how fast you can blow air out of your lungs after you take the deepest breath you can. This is called the Peak Expiratory Flow and is measured in Liters Per Minute (L-min). Strive® PFM measures peak flows from 50-800 L-min and has a low flow scale from 50 L-min to 350 L-min and a high flow scale 200-800 L-min a dual zone peak flow meters within the same device. This measurement indicates the condition of your airways. It is important to know your normal reading. If you use the Strive® PFM every day, you will know when an infection may be starting, even before you feel symptoms.

Everyone will have their own predicted normal reading based on your age, sex and height. Say you are a 30 year old woman who is 65 inches tall. A woman without asthma should have a peak flow reading of approximately 450 L-min.
