DARPA’s GOLDen hour extended EVACuation, or GOLDEVAC, program aims to test whether a field medic could manage a complex polytrauma patient via automated resuscitation tools, starting near the point of injury and continuing throughout the entire evacuation process. Specifically, GOLDEVAC seeks to determine whether it is possible to resuscitate and oxygenate a patient, for up to two days, via a single tube inserted into a patient’s blood vessel, without the risk of blood clots or bleeding.
