Bard's ARCTIC SUN Temperature Management System is a thermoregulatory device that monitors and controls patient temperature within a range of 32°C to 38.5°C. It consists of the Control Module, Remote Display, Fluid Delivery Line, cables and accessories; it pulls temperature-controlled water ranging between 4°C and 42°C through the ARCTICGEL pads (approximately 0.7 liter per minute per pad). This system operates under negative pressure relative to ambient and any break or leak in the system will result in air entering the circuit instead of water leaking out. The system functions in either an Automatic or Manual mode (water temperature increases or decreases automatically to achieve a pre-set patient target temperature determined by the clinician).
