PEAK FLOW METER/SPIROMETER

A peak flow meter is a device that measures how well your lungs are able to expel air. It is also used for measuring the volume of air inspired and expired by the lungs. By blowing a quick blast of air 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 or any other disease affecting your respiratory system, your doctor may recommend that you use a peak flow meter to help track your breathing. Regular use of a peak flow meter can help keep tabs on your respiratory problem by detecting airway narrowing even before you feel any symptoms, giving you time to take the necessary steps before your symptoms get worse.

Usage

1. Move the marker to the bottom of the numbered scale, and connect the mouthpiece to the peak flow meter (if it isn?t already connected).
2. Stand up if you?re able.
3. Take a deep breath, filling your lungs completely.
4. Place your lips tightly around the mouthpiece. Blow as hard and as fast as you can with a single breath.
5. Note the final position of the marker. This is your peak flow rate.
6. Follow the steps above, then blow into the peak flow meter two more times. Record the highest reading of the three.
