Yes, this is a deep hypothermic circulatory arrest. It is however does not help when the cardiac arrest occurs because of the blood loss. The procedure described here is called EPR (emergency preservation and resuscitation) and is a bit more extreme, since it replaces the blood with the saline solution.

Sure, but it's hard to freeze a body without damaging it. Unfreezing it can cause more damage, but the initial damage in an unprepped body is mostly due to all the water in the cells expanding, bursting cell walls, and turning everything to mush on a cellular level.
Yes we know that ice crystals are destructive even for a chunk meat. However it is hard to tell how much damage the current cryonics impose on a body and whenever replacing just the water is enough, considering there wasn't a single successful resurrection yet.
The trial was given the go-ahead by the US Food and Drug Administration. The FDA made it exempt from needing patient consent as the participants’ injuries are likely to be fatal and there is no alternative treatment. The team had discussions with the local community and placed ads in newspapers describing the trial, pointing people to a website where they can opt out.
Is that some sort of advertisement?
