Once applied, how do you loosen to ensure it has not been applied in haste and you do not put the rest of the limb at risk? I appreciate in the video it is of a Pt that has a full amputation, but what if it is an open fracture with a potential catastrophic haemorrhage or a puncture wound with a potential catastrophic haemorrhage, how do we check that it is still clinically needed?
You don't. A tourniquet stays on until the patient is in the OR. Loosening it in between just risks unnecessary blood loss and up to two hours of after application there is no increased risk of amputation from the TQ itself.
Why would you? High and tight is the way to go when the location of the injury cannot be ascertained, e.g. in darkness or under fire when there is no time to expose the extremity. Otherwise, two to three fingers proximal to the injury is sufficient. And exactly what do you mean by "compressing the tibia and fibula"? The point is to raise tissue pressure throughout the entire diameter above systolic arterial pressure to stop bleeding. High and tight would compress the Femur, so just another bone... how's that any different?
@@hazmatops That is a problem with high and tight just as much as with more distal application. Even more so with high and tight because more proximally you find larger muscles with greater diameter change during contraction, both on the arm and the leg.
Torniquete excelente, muito prático p usar.
Very Nice have buyed these for all our Emergency Bags of our Rescue Squad, its a very good and way Cheaper Alternative to CAT.
Interesting, the old elastic Tourniquet from Esmarch's times given new shape and improved with the innovations of our modern day.

So how do you loosen it?
You don't. Once a tourniquet is on, it stays on until the patient is in the operating room.
Note to self. When your mate has no foot and no blood squirting out, it's better to save the torniquet and say a prayer for your friend
Note to self: when your mate's leg turn rubbery a torniquet is just a suggestion.
Note to self. When mate has no foot, it is not a good idea to tell him it's time to stand on his own feet.
I find it questionable that you all don’t know to go high and tight above the knee to avoid compressing the tibia and fibula

Because movement of the extremity can lesson compression of the artery
