High and tight vs above the wound is very dependent on the tactical situation Generally, when under fire (open area, after gaining fire superiority) you visually sweep for hemorrhage If hemorrhage is found, you apply tq high and tight on the extremity, and extricate to behind cover. When under cover, you expose the wound, and apply a second tq above the wound, and loosen the high and tight. Do not remove the high and tight. Only loosen it, in case the patient starts bleeding again because the conversion wasn't successful If the bleeding is veinous, you convert to a pressure type dressing and monitor
the way I think high and tight is so effective is because you're tightening the tq over one bone instead of the lower extremities and has more of a chance of stopping blood flow. I also learned if it continues, its okay to add another right under that tq.
The video fails on a most basic level: I want to see it deployed from the folded-up position to the deployed position. There is a snap-cut at 00:35 where he goes from holding it folded to him sitting on the ground with it deployed. I hear good things about this tourniquet and am comparing it to others, but I have to evaluate how easy it is to deploy.
