Abstract
Asthma is a common chronic disease of children. A good control of symptoms will improve quality of patient life. Inhalation technique is an important aspect in the management of asthma. The better the inhalation technique the better the lung deposition of asthma therapy especially inhaled corticosteroids. This will lead to better control of symptoms and improve adherence to treatment. In the following study the inhalation technique of asthma devices were compared using inhalation technique score system. The asthma devices studied were metered dose inhalers (pressurized MDI) without spacers and dry powder inhalers (DPI). The hypothesis studied was that the inhalation technique score of dry powder inhalers will be adversely affected with concurrent use of metered dose inhalers without spacers.
