N2 - The use of whole body hyperthermia as an adjuvant mode of therapy for metastatic cancer requires an accurate control of core temperature so that the high temperature encountered during treatment may be employed safely. An electrically isolated system has been developed employing a programmable calculator to digitally control a motorized mixing valve regulating water temperature in a set of Hyper-Hypothermia blankets. The water temperature is regulated by feedback control employing patient esophageal temperature as a reference. The system uses a forced air heat exchanger with a reservoir as the source of cold water for cooling the patient once the control temperature has been reached. Whole body hyperthermia is currently being used on a routine basis at the National Institutes of Health, where patient core temperatures have been maintained at 41. 8C plus or minus 0. 1C for up to four hours.
