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).Stand up if you're able.Take a deep breath, filling your lungs completely.Place your lips tightly around the mouthpiece. Blow as hard and as fast as you can with a single breath.
