简要总结

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.

研究组 & 干预措施

Prototype Wearable Stethoscope Evaluation

Experimental

Participants aged 4 to 17 years with asthma will complete asthma control questionnaires, undergo pre- and post-bronchodilator spirometry, and have lung sounds recorded simultaneously using a prototype wearable stethoscope and four Thinklabs One Digital Stethoscopes. Lung sound recordings obtained before and after bronchodilator administration will be used to evaluate agreement between devices and assess associations between detected lung sounds, lung function, and asthma control

干预措施: Prototype Wearable Stethoscope (Device)

结局指标

主要结局

Agreement Between Prototype Wearable Stethoscope and Thinklabs One Digital Stethoscope

时间窗: Single study visit (up to 90 minutes).

Agreement between the prototype wearable stethoscope and the FDA-cleared Thinklabs One Digital Stethoscope in the classification of normal versus abnormal lung sounds, assessed using Cohen's Kappa.

Association Between Lung Sounds and Asthma Control Scores

时间窗: Single study visit (up to 90 minutes).

Association between abnormal lung sounds detected by the prototype wearable stethoscope and asthma control as measured by the Childhood Asthma Control Test (cACT) or Asthma Control Test (ACT).
