About Peak Flow Meters for Asthma in Children

Overview

A peak flow meter is a handheld device used to measure how well the lungs are functioning by tracking peak expiratory flow rate (PEFR). It is commonly used by people with asthma, including children.

Readings from these devices not only allow children and their care takers to identify early signs of worsening asthma but also provide doctors valuable information on a person’s best peak flow. Abnormalities in the readings would indicate the need for action, such as adjusting medication or seeking medical help.

The following are steps to use a peak flow meter:

• Stand up straight and take a deep breath.
• Place your lips tightly around the mouthpiece.
• Blow out as hard and fast as you can into the meter.
• Repeat the process three times, recording the highest reading
• Compare the reading to your personal best or normal range provided by your doctor.
• Follow your doctor's instructions on when and how often to measure and record your peak flow.

Remember, it’s crucial to work with you doctor to create a personalized asthma action plan outlining steps to ensure prompt and appropriate intervention.
