The treatment of acute asthma exacerbations is usually based on a clinical scoring system. It cannot be performed on small children. However, there is a method called Oscillometry that uses a handheld device to measure respiration. Oscillometry has an objectivity that other assessments of lung function lack. Studies also suggest that it can produce accurate results in children in outpatient care. However, there have not been many evaluations of the effectiveness of Oscillometry in an ED setting. This study aims to determine whether Oscillometry is feasible in the emergency department.


The study was performed on 20 children between the age of 4 and 18 who had been admitted to an ED for acute asthma exacerbations. Assessments of vital signs, pulmonary asthma score, and Respiritory Impedence were collected with Oscillometry three times: Before treatment, immediately after treatment, and two hours after treatment.


The results of the study demonstrate that Oscillometry is feasible, responsive, and safe for children who are admitted to the Emergency Department for acute asthma exacerbations.
