Choking occurs when an object blocks the passage of air into the lungs.
Choking is the mechanical obstruction of the flow of air from the environment into the lungs. Choking prevents breathing, and can be partial or complete, with partial choking allowing some, although inadequate, flow of air into the lungs. Prolonged or complete choking results in asphyxia which leads to anoxia and is potentially fatal. Oxygen stored in the blood and lungs keep the victim alive for several minutes after breathing is stopped completely. Choking can be caused by: The type of choking most commonly recognized as such by the public is the lodging of foreign objects (also known as foreign bodies, but consisting of any object which comes from outside the body itself, including food, toys or household objects) in the airway. This type of choking is often suffered by small children, who are unable to appreciate the hazard inherent in putting small objects in their mouth. In adults, it mostly occurs whilst the patient is eating.
