Senior Airman Samuel Hahn, 47th Medical Group Public Health technician, completes chest compressions on a training mannequin at the 47th Medical Group training classroom Oct. 23, 2014. About 92 percent of sudden cardiac arrest victims die before reaching the hospital, but statistics prove that if more people knew cardiopulmonary resuscitation, more lives could be saved. Immediate CPR can double, or even triple, a victim’s chance of survival. (U.S. Air Force photo by Staff Sgt. Steven R. Doty)(Released)
