A peak flow meter is a portable, easy-to-use device that measures how well your lungs are able to expel air. By blowing hard through a mouthpiece on one end, the peak flow meter can measure the force of air in liters per minute and give you a reading on a built-in numbered scale. If you have asthma, your doctor may recommend that you use a peak flow meter to help track your asthma control.
