Conclusion
In conclusion, up to 20% of patients with asthma may have positive LUS findings when not experiencing an acute asthma exacerbation. Most of these findings were on the right lateral or right anterior zone (60%), mild in severity, and limited to 1-2 intercostal spaces within one lung zone. Such findings need to be taken into consideration when using LUS for the evaluation of a pediatric patient with an acute asthma exacerbation.
