Abstract
A method and system for monitoring physiological parameters is useful for remote auscultation of the heart and lungs. The system includes an acoustic sensor () that has a stethoscopic cup (). A membrane () is positioned adjacent to a first end of the stethoscopic cup (), and an impedance matching element () is positioned adjacent to the membrane (). The element () provides for acoustic impedance matching with a body such as a human torso. A microphone () is positioned near the other end of the stethoscopic cup () so as to detect sounds from the body. A signal-conditioning module () is then operatively connected to the acoustic sensor (), and a wireless transceiver () is operatively connected to the signal-conditioning module (). Auscultation can then occur at a remote facility that receives signals sent from the transceiver ().
