About this trial

The goal of this clinical trial is to evaluate a prototype wearable stethoscope designed to record lung sounds and assess asthma control in children and adolescents with asthma aged 4 to 17 years who are able to perform spirometry. The study aims to determine whether the prototype wearable stethoscope can accurately detect clinically meaningful changes in lung sounds associated with asthma control and response to bronchodilator treatment.

The main questions it aims to answer are:

* Does the prototype wearable stethoscope demonstrate agreement with recordings obtained from commercially available Thinklabs One Digital Stethoscopes in identifying normal and abnormal lung sounds? * Are lung sounds detected by the prototype wearable stethoscope associated with asthma symptom control as measured by the Childhood Asthma Control Test (cACT) or Asthma Control Test (ACT)

Researchers will compare recordings obtained from the prototype wearable stethoscope with recordings obtained from FDA-cleared Thinklabs One Digital Stethoscopes to evaluate the prototype device's ability to detect abnormal lung sounds and changes in lung sounds following bronchodilator treatment.
