Choking is when breathing is hindered or stopped by obstruction of the throat or windpipe.

Without oxygen, the brain begins to die within 4 to 6 minutes. Rapid first aid for choking can save a life.

Following the expulsion of the object that caused the choking, keep the person still and get medical help. All choking persons should have a medical examination, since complications can arise not only from the choking incident, but also from the first aid measures that were taken.

Occasionally an object will enter the lung. While the person may appear to improve and breathe normally, in a few days symptoms such as wheezing, persistent cough, and pneumonia may develop. If this happens, get medical help immediately.
