How to treat asthma in pediatric patients
Assess the severity of your child's symptoms during an attack.
Have your child inhale as deeply as they can and close their lips tightly around the meter's mouthpiece. They should then blow out as hard and quickly as possible.
A peak flow meter is a device that measures air flow from the lungs. Your child should use their peak flow meter when they're not experiencing symptoms to establish their normal range.
