Description

An electronic precordial stethoscope was used on 25 subjects to record respiratory sounds during sedation. The subjects were sedated using different combinations of remifentinal and propofol. Along with the audio data several other measurements were taken such as respiratory flow, pulse oximetry, ECG, and many others. The data from the stethoscope are currently being analyzed and compared to the flow data. Some preliminary data and findings are discussed. Obstructive sounds are compared to normal respiratory sounds and possible detection algorithms are explained.
