You are eating at a restaurant when a man suddenly stands up and grasps his neck. he is starting to turn blue and is unable to talk. state your management of this casualty.?

If a man is grasping his neck and turning blue, he is likely choking. I would first ask him if he can cough or speak; if he cannot, I would perform the Heimlich maneuver by standing behind him, placing my arms around his waist, making a fist with one hand just above his navel, and thrusting inward and upward until the object is expelled or he becomes unconscious. If he becomes unconscious, I would call for emergency assistance and begin CPR if necessary.
