An inexpensive device, peak-flow meter, may be helpful. You can measure the amount of air you can blow out of your lungs. You can use the peak flow meter every day at your home. Keeping track of how much air you blow out lets you know when you need to take additional medicine or call your doctor. Your health care provider should teach you how to use your peak flow meter and what to do if your asthma gets worse.
Asthma inhalers can be hard to use.
Many people with asthma do not use their inhaler correctly. If you are not using the inhaler correctly, you may not be getting the correct dose of medication into your lungs. A spacer may make the inhaler easier to use. Always review how to use you inhaler with your physician. There are numerous asthma medications, each with different strengths.
