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.
