Telemedicine System and Intelligent Monitoring System Construction of Pediatric Asthma Based on the Electronic Stethoscope

The purpose of this study is to retrofit the existing electronic stethoscope, improve the quality and efficiency of signal acquisition and the intelligent degree of information processing, decrease the manual action of electronic stethoscopes implemented by parents of asthma children, simplify the process of data transfer and the user's operational cost using signal processing, artificial intelligence technology, thus decreasing the feedback cycle between patients and clinicians. Eventually, we will construct an intelligent monitoring system based on the modified electronic stethoscope and explore the interactive remote management approaches on children's asthma at the same time, thus achieving revolutionized remote management of asthma.
