Answer: Give CPR, starting with chest compressions, if the choking person loses consciousness. Every time you open the lips to breathe, look inside to eliminate any things you notice. Perform abdominal thrusts before dialing 9-1-1 or your local emergency number if you're the sole rescuer.
Explanation: Another thing always look in the mouth to see if the object is in there or is coming up.
