I ditto Jim on the tourniquets...the mantra is 'High, Wide, and Tight' so, high up into the armpit or groin, this is where the artery is closest to a bone so it can be compressed against it, have the band at least 2" wide, and make it TIGHT, like painful tight. Write 'T' and the time on the patient's forehead. They have 1 hr. before any knock on effect starts to happen from the tourniquet. It lets the EMT's/doctors know they might have extra things to consider once they arrive for treatment.
Israeli bandages on Wesspur are like $8...that's not expensive.
Also agree about cervical spine collars. They are fast going out of recommendation. IF a person is capable of self rescue, then they don't need a c spine collar, just bolster their head with towels and if they have to be moved then one person is tasked with holding the head and calling the movements.
So many collars are put on incorrectly they actually do little to immobilise the spine, and can make the patient uncomfortable and even panicky.
Air goes in and out, blood goes round and round, any deviation from this is bad...rectify it. If someone cannot breathe, or is haemorrhaging badly (catastrophic amputation or arterial bleed, do what you need to do to fix this, even to the point of moving them from a position where one might suspect a spinal injury. If you don't they will die.
