Asthma is a chronic and common inflammatory disease of the airways. If you have asthma, the airways of your lungs swell, narrow and produce extra mucus. Some patients have minor asthma that’s managed with occasional use of an inhaler, while others may need daily medication or experience a life-threatening asthma attack.
Treating asthma or COPD is typically done using some type of inhaler device. The technique or method in how the medication is delivered is crucial to efficacy and health outcome. Device technique should be assessed regularly by a trained health care professional to ensure proper use.
