Peak Flow Meter

This is a small hand-held tube that can measure what is happening in your breathing tubes.  You can have one at home and measure your peak flow by blowing into it as hard and fast as possible.  You will be shown how to measure it and compare it with what you can blow when you are well as part of your asthma management plan if you think you are having an asthma attack.
