What’s Inside?
This abstract is among the first validation studies of the RESP® Biosensor, a wearable device designed to continuously capture lung sounds for remote patient monitoring. In volunteers with COPD, asthma, CHF, and chronic cough, RESP recordings were compared against the Littmann® 3200 stethoscope using a rigorous “4:2:1” paradigm, with blinded clinician review confirming high fidelity across devices.
Patients were asked to cough, swallow, perform breathing maneuvers, and even complete tasks under background noise, demonstrating the accuracy of RESP in real-world conditions. In a separate study, the device provided eight hours of continuous cough monitoring, offering new insights into cough architecture and the distinction between intrathoracic and extrathoracic origins.
Together, these results validate the RESP® as a reliable tool for continuous, remote auscultation and lay the groundwork for algorithm development and patient monitoring.
