Asthma inhaler. Young woman using her inhaler to treat an asthma attack. Asthma is a condition in which the 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.
