>>965480>so how do you prevent blood loss given a serious injury?The goal is to control it and prevent harm from it, not altogether prevent or stop it. Do the usual things first-direct pressure, elevation, if necessary moving to pressure points, clamping any big arterial source, applying tourniquets. You can do most of these things without any equipment. Also the person's physiologic responses will usually control even major bleeds without any help.
It takes an avg man 32oz of blood volume loss for symptoms to start, most people would think 6 oz is a lot if they saw it. But even big injuries like amputations take some time to lose a significant amount, and losing 32 oz instantly and going into shock probably isn't survivable.
>I heard they don't really recommend tourniquets anymore unless you can accept the possibility of losing the limb it's applied to.Depends on the setting. In the military they use them earlier because they can be used in combat, and people tend to have multiple sources of blood loss, soldiers aren't doctors, etc. Civilian medicine can be more careful with them, and yes limbs can be lost when they're on more than a few hours. But if you're still worried about saving the limb more than your life the tourniquet probably isn't needed anyway.
