Peak Flow Meter
A peak flow meter is a device that measures how fast air can move out of your child's lungs. With an asthma attack, the breathing tubes of the lungs swell and become narrowed. The narrowed tubes make it difficult to breathe. Using a peak flow meter daily helps to monitor your child's asthma. It may tell you when your child's breathing tubes are narrowing before he / she begins to have symptoms. By having your child take his / her rescue medicine when this happens, you may be able to stop a severe attack before it occurs.
Using a peak flow meter daily can help you:
- Monitor your child's breathing
- Identify when your child should take rescue medicine
- Stop a severe attack from occurring
- Identify when to call your child's doctor or seek emergency care
