ECMO machine
Members of the 59th Medical Wing Extra-Corporeal Membrane Oxygenation clinical care support team inspect an ECMO machine during an exercise July 1, 2009, at Wilford Hall Medical Center, at Lackland Air Force Base, Texas. The ECMO machine is a heart-lung bypass device that circulates and oxygenates the blood, giving diseased or damaged lungs a chance to heal. (U.S. Air Force photo/Staff Sgt. Robert Barnett)
