How to Order a Peak Flow Meter

A peak flow meter is a small device that asthma sufferers use to tell how well their medication is working by measuring the amount of air moving through their lungs. A peak flow meter can warn you of an impending asthma attack so you can take the necessary precautions to interrupt it, such as using your quick-acting asthma inhaler.
