Effectiveness, Safety and Ease of Application of Excel Cryo Cooling Collar to Rapidly Reduce Core Brain Temperature

Therapeutic hypothermia in the study will be initiated by The Excel Cryo Cooling system consisting of a unique cervical immobilization collar and a cooling element. Once activated, the cooling element achieves a temperature of -3.0 °C to -5.0 °C within seconds. The collar is fitted around the subject's neck and the cooling element is applied the the front of the neck over the carotid arteries and secured in place by the collar. The Excel System provides consistent cooling regardless of patient size or weight, by cooling of the blood traveling through the carotid triangles.
