What are the 8 step if a choking person becomes unconscious, what steps should be taken to secure them assistance?

911, Heimlich, CPR. If the person is already unconscious, immediately call 911, then attempt a heimlich maneuver, and then begin cpr. If there is something obviously in the mouth, a sweep from side to side through the mouth may clear it, but the danger is pushing it in deeper.
Choking. Calm yourself apply heimlich by standing behind the person reaching around making afist with one had and cupping it with the other and applying a sharp forceful serious jerk upwards to cause the air in their lungs to blow out their mouth if they have already passed out lay them on their back and straddle their waist and put your hands together like as above and push upwards hard and fast once.
