Childhood asthma is a major public health issue. This paper describes the correct techniques of administering MDIs with spacers and nebulizers in children to control asthma. The study was a descriptivecross sectionalstudy designed to evaluate the parental knowledge. The information was obtained by interviews conducted with the parents/guardians using standardised questionnaires on knowledge, choice and effect of education on adherence to asthma control. The results of the study suggest that there are gaps in knowledge regarding MDIs with spacers in asthma management, and education to correct misconceptions about the treatment and correct technique of use of device should be provided.
