Abstract The incidence of pediatric asthma is increasing in most countries. Pulmonary function tests (PFTs) are used to determine asthma severity in preschool children, and are seldom performed in preschool children due to little cooperation, coordination. Interrupter resistance technique (Rint) is one of the easiest ways to assess respiratory resistance during tidal breathing with minimal subject cooperation. It has, therefore, been largely used in young children unable to perform reliable spirometry. The technique is good enough to allow assessment of bronchial reactivity. The aim of this observational cross- sectional study is to assess the feasibility of performing interrupter resistance technique (Rint) in asthmatic preschool children as a noval technique which needs minimal cooperation in this young age group. Our results showed that only 18.8 % of children aged 2-3 years succeeded in performing the test, while 100 % of children aged above 3 years succeeded in performing the test.
