MODEL RELEASED. Asthma inhaler use. Elderly woman using an inhaler to treat an asthma attack. During an asthma attack,small airways (bronchioles) in the lungs constrict,making it difficult to breathe. This causes wheezing,coughing and breathlessness. The inhaler is an aerosol pump,which releases bronchodilator drugs that widen the airways. Asthma attacks can be brought on by exercise,allergic reactions and cold weather. Asthma usually develops during childhood,and generally improves as the patient matures | |
