The U.S. Military no longer maintains overseas extracorporeal membrane oxygenation (ECMO) capability for patients with severe lung injury including acute respiratory distress syndrome (ARDS). The authors present a case of severe ARDS at a military hospital in Afghanistan with limited capability for rescue therapies to include presentation, treatment, transport, and use of ECMO in the deployed military environment at one Role 3 medical facility. Lack of ECMO in the overseas environment is a significant gap in U.S. Military medical capability. The authors propose a novel solution, "ECMO packs," for prepositioning at strategic Role 3 facilities for early intervention in patients with severe lung injury to close this lethal and unnecessary capability gap.
