I'm not medical but I think crush injuries and harness hang syndrome are different conditions. I remember googling this about 6 months back and there seemed to be a lot of inconsistency in the literature. Either that or I couldn't understand it.

From memory harness hang occurs when not enough oxygen reaches the brain as all the blood stays down in the legs. I'm guessing this would kill an unconscious climber relatively quickly (respiratory failure because the brain stops working?).

Crush injury involves involves impairment of circulation/lympahatic systems. When the load is released toxins flood the body. I'm guessing this does bad things to a number of the body's systems (cardiac, renal etc).

An immobile casualty hanging in a harness is at risk of both. In either case getting the weight of their harness would be the number 1 priority.

Could be totally wrong on all of the above. Any paramedics or emergency doctors out there want to set me straight?
