I've heard "induce hypothermia" a few times in reading about it (including here ) . To be clear, this was in context to what could occur and/or may have occurred in similar cases. It's not clear that this happened here, but hypothermia occurs when your body temp falls below 95 degrees.Just watching the news this morning and they had a leading cardiologist on who echoed this opinion. But he went further and said heart restart isn't the end game. He said a critical concern is potential neurological injury if the brain does not receive sufficient blood flow / oxygen. An additional step to help avert this is to induce a coma and concurrently lower the body's core temperature (I didn't hear him if he mentioned what that temperature is). Then he said there is a significant degree of discretion on when to return the body to normal temp and bring the patient out of the coma.
