Just a guess, but it might have something to do with whether the brain is able to be saved vs. just the body.

  yes but why wouldn't you try regardless of knowing? In the time you spend gathering temp data, you could already be reviving

    I imagine they were doing that regardless, but were very happy to learn that there was an actual chance of success.

      That, in fact, is how I figured it went. I did not get to see the video, so everything remains speculation.

    Because chances are extremely slim: > Various degrees of hypothermia may be deliberately induced in medicine for purposes of treatment of brain injury, or lowering metabolism so that total brain ischemia can be tolerated for a short time. Deep hypothermic circulatory arrest is a medical technique in which the brain is cooled as low as 10 °C, which allows the heart to be stopped and blood pressure to be lowered to zero, for the treatment of aneurysms and other circulatory problems that do not tolerate arterial pressure or blood flow. The time limit for this technique, as also for accidental arrest in ice water (which internal temperatures may drop to as low as 15 °C), is about one hour.[84] Also you can't just warm the body back to 38 degrees, it should be carefully brought up AFAIK.
