Background: Around the world, asthma affects children and is a common chronic respiratory condition. For the disease to be managed effectively, an accurate assessment of asthma control is essential. A non-invasive method called "Impulse Oscillometry (IOS)" has become more popular for evaluating the respiratory function in asthmatic kids. This study's goal was to assess IOS's contribution to determining children's asthma control.

Methods: For this cross-sectional study, 100 kids with an asthma diagnosis who were between the ages of 5 and 16 were enrolled. Each participant had lung function testing with the IOS and had their demographic and clinical information gathered. The "Asthma Control Test (ACT)" was used to evaluate asthma control. The IOS parameters were examined and contrasted across various asthma control levels.

Results: There were 42 girls and 58 boys in the study population, with a mean age of 9.7 3.5 years. The majority of children (60%) had uncontrolled asthma, which was followed by asthma that was only moderately (24%) and fully (16%) controlled. IOS metrics including resonant frequency (Fres), reactance at 5 Hz (X5), and resistance at 5 Hz (R5) were discovered to substantially differ amongst the various asthma control levels (p 0.05). When compared to asthma that was under control, the R5 value was higher in uncontrolled asthma (p <0.001). When compared to asthma that was under control, X5 and Fres were lower in uncontrolled asthma (p <0.001).

Conclusion: As a result of this study, it is possible to evaluate a child's asthma control using IOS parameters. The levels of asthma control were observed to considerably differ in R5, X5, and Fres. Clinicians may find IOS to be a helpful tool in managing children's asthma.
