It will be lightweight and easily folded for transport. The problem with these approaches is that they could very easily lead to the freezing of patient tissues. The second major priority for a local group is means for cardiopulmonary support. In a patient who has just been declared legally dead, most of the cells are still very much alive. Oxygen and nutrient can be supplied to these cells by artificial circulation to prevent ischemia.
Circulation is necessary to add medications to prevent blood-clotting and ischemic damage.
An endotrachial tube is useful to prevent an unconscious patient's tongue from obstructing the airway. Use of power from oxygen-pressure rather than electricity makes the unit much more portable. An industrial-grade oxygen tank is adequate. Mouth-blown air face masks also reduce contamination, but require more work. Monitoring a patient to determine moment of death is best done with a pulse oximeter .
