From Stethoscope to Wearable
Lung Sound Data at Your Fingertips
Traditional stethoscope auscultation has been a gold standard for assessing respiratory health for over 200 years, with lung sounds such as cough, wheeze, rhonchi, or crackles indicating blockage and other problems in the airways. However, it is limited to episodic, in-person visits.
As we developed a solution for remotely monitoring patients with chronic respiratory disease, we designed the RESP® Biosensor to capture lung sounds—extending the temporal and geographic reach of stethoscope auscultation and providing clinicians with a continuous window into patient lung health.

“With this information we can predict if the patient is doing better or worse and intervene ahead of time to prevent the patient from having major complications”
– Sadia Benzaquen, MD, Chair of Pulmonary Critical Care, Einstein Medical Center
The RESP® Biosensor: Technology Overview
- Clinically validated accuracy, with equivalent performance to Littman 3200 electronic stethoscope¹
- Passively collects lung sounds such as cough and wheeze and breathing patterns to offer objective data on respiratory status passively and remotely
- Patient-friendly form factor: wireless and discreet without interfering with daily life

Filling a Gap in Standard of Care
While pulmonary function tests, episodic auscultation, and patient-reported outcomes remain standard of care in respiratory care and research, RESP® addresses key limitations of each approach.
