A new technological approach to radiant heat whole body hyperthermia.

A new methodology for administering radiant heat whole body hyperthermia (WBH) in humans is described. The technology utilized circulates hot water in a cylinder constructed from copper tubing; the design incorporates a counter current distribution system to maintain thermal constancy. The tubing is coated with a temperature resistant high emissivity finish. Other features include a humidification system to eliminate evaporative heat losses. Data accrued from initial evaluation of this apparatus with a canine model shows that there was no detectable WBH-related hematological, biochemical or physiological toxicity. The perceived advantages of this WBH-system are discussed.
