What is a peak flow meter?

ANSWER

If you have asthma or other problems with your lungs, your doctor might ask you to do your own lung tests at home. A gadget called a peak flow meter lets you do that. You hold it in your hand and blow into it. You get a reading on how well your breath flows out of your lungs.

Your doctor will say if a home test is right for you. If you have mild asthma, you may not need one. But it could help if your condition is worse. A meter also might be handy if you have chronic bronchitis or emphysema.
