Electromagnetics in Medical Applications: The Cardiopulmonary Stethoscope Journey

Abstract

Pulmonary edema, caused by abnormal accumulation of fluid in the lungs, is a clinical manifestation of chronic illnesses such as congestive heart failure and kidney failure. Early detection of pulmonary edema is the cornerstone for management of these diseases. Although methods for detection of pulmonary edema are clinically available, they are invasive and noncontinuous. The introduction of noninvasive and continuous methods would be considered by some in the medical community as “the holy grail.” The cardiopulmonary stethoscope (CPS) system was developed to address these needs. The CPS system is a noninvasive device capable of continuous remote monitoring of heart rate, respiration rate, and changes in lung water content. Developed capabilities and features of the CPS system include wearable sensors, mobile-based platform, advanced signal processing techniques for feature extraction, realistic and dynamic 3D modeling, and clinical validation of its capabilities. Clinical validations were performed using animal and isolated lung experiments and testing on healthy populations as well as heart failure and hemodialysis patients. Results from these studies show good agreement with results from clinical standard monitoring procedures.
