Using a peak flow meter is straightforward, but it is essential to follow the correct steps to ensure accurate readings:
Ensure the meter is set to zero. Have the child stand up straight. Instruct the child to take a deep breath and then blow into the mouthpiece as hard and fast as possible. Record the number indicated on the meter. Repeat the process three times and record the highest number.
It's crucial to clean the mouthpiece regularly to maintain hygiene.
