Auscultation of heart sound and breathing sound in anesthesia is very important, because it can provide the information of patient's cardiorespiratory system. In operating room, anesthesiologists use esophageal stethoscope, which is a device to measure heart sound or respiratory sound by inserting a catheter into the esophagus close to heart. It is not only low cost and very simple to use for anesthesiologists, but provides the clinical data such as heart sound, breathing sound, core temperature. But it cannot not quantize and analyze the various data objectively. For this reason, we designed portable digital esophageal stethoscope system(PDES). PDES is a device that can acquire the data of heart sound and breathing sound by connecting microphone to the end of esophageal catheter. Besides, it can transmit the wireless data to a PC using Bluetooth technology and display on its screen. It displays the magnitude of heart sound, heart sound waveform, core temperature by using Heart Sound 1.0, that is developed for this purpose.
