a. Repeating the procedure for a total of three readings
b. Breathing in deeply through the mouth-piece

B
Peak flow should be monitored on a daily basis to determine if the asthma patient has adequate airflow. The reading helps determine if treatment should be adjusted. The patient should stand to achieve adequate chest expansion while taking a deep breath. The patient then blows as hard and fast as possible into the device with the mouthpiece in the mouth and the lips clamped firmly around it for a tight seal. The procedure should be performed three times with the highest reading recorded.
