Devices for Emergency Hypothermia and Military Applications
Abstract
Ongoing research by the Safar Center for Resuscitation Research and others, indicates the need for the development of compact, mobile, and portable devices for the induction of therapeutic hypothermia. During the first year (1 September 2001-31 August 2002) we have developed the cooling requirements for the induction of mild (34 degrees C) to moderate (30 degrees C) and profound (10-20 degrees C) hypothermia in the average human body. We then researched the available literature for viable methodologies that could be used as a cooling means to incorporate into cooling devices for the induction of both mild and profound hypothermia. Computer modeling, mathematical analysis, and laboratory characterization were used to evaluate various concepts for the cooling means and the heat exchanger designs. Experimental prototypes of the selected methodologies were constructed and evaluated. From this work three cooling methodologies were selected for inclusion in the devices and we determined that existing blood heat exchangers do not have the capacities required for this application and we therefore must develop custom heat exchangers.
