Minimally Interrupted Cardiac Resuscitation by Emergency Medical Services for Out-of-Hospital Cardiac Arrest

From the Journal of the American Medical Association (JAMA):

Instruction for EMS personnel in MICR, an approach that includes an initial series of 200 uninterrupted chest compressions, rhythm analysis with a single shock, 200 immediate postshock chest compressions before pulse check or rhythm reanalysis, early administration of epinephrine, and delayed endotracheal intubation.

Among the 886 patients in the 2 metropolitan cities, survival-to-hospital discharge increased from 1.8%  before MICR training to 5.4%  after MICR training. In the subgroup of 174 patients with witnessed cardiac arrest and ventricular fibrillation, survival increased from 4.7%  before MICR training to 17.6% after MICR training.
