Overview
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 asphyxiation which leads to hypoxia and is potentially fatal.

Causes
Choking can be caused by:
- Introduction of a foreign object into the airway, which becomes lodged in the pharynx, larynx or trachea.
- Respiratory diseases that involve obstruction of the airway.
- Compression of the laryngopharynx, larynx or trachea in strangles.
Foreign Objects
The type of choking most commonly recognised as such by the public is the lodging of foreign 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.
