Dear oh dear.
VSF, whilst your reaction to my gentle post is exactly what we have come to expect from the 'experts', to humour you (and maybe assist) a quick google search produces this:
Retrieval of a victim from cold water immersion must be performed with caution. Sudden reduction of the "hydrostatic squeeze" applied to tissues below the water's surface may potentiate hypotension, especially orthostatic hypotension. Since a hypothermic patient's normal cardiovascular defenses are impaired, the cold myocardium may be incapable of increasing cardiac output in response to a hypotensive stimulus. A victim's vertical posture may also potentiate hypotension. Hypovolemia, secondary to combined cold- and immersion-induced diuresis, and increased blood viscosity potentiate these effects. Peripheral vascular resistance may also be incapable of increasing, since vasoconstriction is already maximal because of cold stress. The net result of sudden removal of a hypothermic patient from the water is similar to sudden deflation of antishock trousers on a patient in hypovolemic shock: abrupt hypotension. This has been demonstrated experimentally in mildly hypothermic human volunteers, and it has been suspected as a cause of post-rescue death in many immersion hypothermia victims. Accordingly, rescuers should attempt to maintain hypothermic patients in a horizontal position during retrieval from the water and aboard the rescue vehicle. If rescuers cannot recover the patient horizontally, they should place the victim in a supine posture as quickly as possible after removal from cold water.
My post was a gentle prod, nothing more, the SME on the end of the wire made an initial choice (to take 2 strops), then made the choice to use 1, fine, thats his call. Everyone does things differently, thats the point, which a few of our esteemed posters will never, ever accept
