Choking

Choking can take place due to:
Swallowing a large piece of food
Swallowing food that is not well chewed
Eating food quickly
Eating and talking
Consuming alcohol before a meal
Wearing loose-fitting dentures
Walking / playing with food in mouth

Symptoms
Hands will grasp the throat
Breathlessness
Noisy breathing
Inability to cough
Skin, nails and lips may turn blue
The person may become unconscious

Immediate care

If the person cannot cough or speak, begin the Heimlich maneuver(as shown in illustration) immediately to dislodge the object blocking the windpipe. The Heimlich maneuver creates an artificial cough by forcing the diaphragm up toward the lungs.
If you are choking and alone: You can perform the Heimlich maneuver on yourself by giving yourself abdominal thrusts. Or position yourself over the back of a chair or against a railing or counter and press forcefully enough into it so that the thrust dislodges the object.
