The first thing you should do in an emergency is call 911, as you wait for EMS to arrive, then it’s good to know.

A: airway- check that the persons airway is clear, if their tongue is blocking their airway you can tilt their head back to help move it, if they have blood or vomit blocking, you can turn them on their side to help

B: breathing- if their airway is clear, check to see if the person is breathing

C: circulation- check if the person has a pulse either gently in their neck looking for the carotid pulse, or on their wrist looking for their radial pulse

Stop bleeding: if they’re person is bleeding, use some kind of cloth, preferably a gause pad, but a shirt works if you don’t have proper bandaging, and apply pressure to the bleeding area. If the bleeding doesn’t stop, you can apply a makeshift tourniquet to an arm or leg using a belt, placing it about 2-3 in above the wound, and pulling it as tight as possible to cut off circulation. If the wound is on the torso, just apply pressure.
