What Else Should I Do to Help Control My Asthma?

To control asthma, it's also important to keep track of how well lungs are functioning. Asthma symptoms are monitored using a peak flow meter -- a device that measures the speed of air that coming out of the lungs when you exhale forcefully. This measurement is called peak expiratory flow (PEF) and is calculated in liters per minute.

The meter can alert you to changes in the airways that may be a sign of worsening asthma before you have symptoms. By taking daily peak flow readings you can learn when to adjust medications to keep asthma under control. Your doctor can also use this information to adjust your treatment plan.

Can Asthma Be Cured?

There's no cure for asthma, but it can be treated and controlled. In most cases, people with asthma can live free of symptoms by following their treatment plan.
