Wearable Electronic Breath Sound Sensing Device
Pilot Study of Wearable Electronic Breath Sound Sensing Device for Monitoring of Breath Sounds in Pediatric Patients with Asthma
Emory University
10 participants
Feb 26, 2025
OBSERVATIONAL
Conditions
Summary
This study will assess the ability of a wearable stethoscope to monitor wheezing in high-risk asthma patients admitted at Children's Healthcare of Atlanta. This study is important to assist in the health management of patients with chronic lung diseases that can experience exacerbations leading to their health worsening and requiring hospitalization. The population that will be approached for this study will include 10 pediatric subjects hospitalized at Children's Healthcare of Atlanta for an asthma-related exacerbation. Participants will wear the patches for up to 8 hours on their chest and back wall from their date of consent until their hospital discharge. This may range from the participant taking part in 1 to 14 visits that could last up to 8 hours.
Eligibility
Inclusion Criteria4
- Age 6-17 years
- Diagnosis of persistent asthma
- Being treated for an acute asthma exacerbation
- Parent can speak and understand English
Exclusion Criteria5
- Unable to provide consent for the study
- History of prematurity
- History of other chronic lung conditions - cystic fibrosis, bronchiectasis, or primary ciliary dyskinesia
- History of latex allergy or allergy to medical tape adhesive
- Patients currently using another medical device - implanted pacemaker or vagal nerve stimulator or diaphragm pacing device
Interventions
The device is a soft, wearable stethoscope designed for continuous, comfortable monitoring of patients for abnormal breath sounds, such as wheezing, which can indicate asthma exacerbations. It automatically detects and diagnoses abnormal breath frequencies, wirelessly transmitting data for analysis. Preliminary materials have shown biocompatibility, ensuring the device is safe for use in children. A key feature is its machine-learning algorithm, which can classify and differentiate normal from abnormal sounds with an expected accuracy above 80%. Initial in vivo tests will compare the device's findings to those of a commercial-grade stethoscope in healthy subjects and individuals with asthma. Breath sound data will be used to improve the detection of wheezing sounds from these continuous recordings based on frequency and amplitude analysis of the recordings.
The study PI will auscultate the participant's lungs at enrollment to ensure that wheezing is present before beginning the continuous recording of the participant's lung sounds. The PI will assess the participant's respiratory status daily at the start of each breath sound recording session.
