An Esophageal Multiprobe for Temperature, Electrocardiogram, and Heart and Lung Sounds Measurements

An esophageal multiprobe capable of continuous monitoring of body core temperature, heart and lung sounds, and ECG during surgery was constructed using tubing having integral conductive plastic strips. A temperature readout instrument was designed for compatibility with this device. Clinical testing indicates promise for the development of an inexpensive disposable device for use with patients under general anesthesia.
