Impulse Oscillometry in The Monitoring of Pediatric Asthma

Impulse oscillometry (IOS) is a lung function study that uses pulse waves to measure respiratory impedance.It requires little effort, which makes it easily reproducible and useful when monitoring children with asthma.The accuracy of its interpretation depends on the reference predictive values.The most recent evidence positions it as a good method to predict loss of control, future risk of exacerbations, and persistent alterations of lung function in pediatric asthma.
