N2 - Objective: Lung function testing is used in diagnosing asthma and assessing asthma control. Spirometry is most commonly used, but younger children can find performing this test challenging. Non-volitional tests such as airwave oscillometry (AOS) may be helpful in that population. Our aim was to compare the success of spirometry and AOS in assessing bronchodilator responsiveness in children with asthma or wheezeMethods: AOS was conducted alongside routine lung function testing. Resistance at 5Hz (R5), the difference between the resistance at 5 and 20Hz (R5-20) and the area under the reactance curve (AX) were assessed. Patients aged between 5 and 16 years old attending clinic with a presentation of wheeze or asthma were assessed. Patients performed AOS, followed by spirometry and were then given 400µg salbutamol. The tests were repeated 15 minutes after the bronchodilator challenge.Results: Lung function testing was performed in 47 children of whom 46 (98%) and 32 (68%) performed acceptable baseline oscillometry and spirometry, respectively (pConclusions: Oscillometry is a useful adjunct to spirometry in assessing lung function of young asthmatic children.
