If the casualty is on a boat then they will try and lower a stretcher, by hi - line transfer. We did this the same day.
Ah, that's really interesting. I had wondered if things had changed as I could only recall seeing a strop under the arms being used but I may not have been watching closely.

I suppose it's for this reason the Yanks use a rescue cage BUT from what I have seen the lack of control is terrible. The cage seems to spin totally out of control and it always looks so clumsy - I don't know why they never seem to use a winchman on the cable at the same time as the casualty.

Cuff was put (I believe) on the bicep. That was done only during treatment. I have no idea how the thing pulled the vacuum on the skin, but I remember e-mailing one of the testers who replied that very little suction was required; not even enough to be uncomfortable.

The "do not immerse in warm water" thing is because the all the capillaries exposed to the warm bath open well before the core temp starts to increase, which leads to all sorts of weird problems. With the new device, the warming is much more gradual, and tends towards the core first (well, the arm, then the core), so less shock to the system.

Be interested in a link if you can find one?
As I said, the device was experimental, plus it was a few years ago. But I'll see what I can find.

Here is an excellent, practical resource. I know one of the co-authors personally and he is a world reknown researcher on cold water immersion physiology.
