Cause of choking: Choking in infants and small children is caused by small foreign object blocking one of the airways. If children play with objects in their mouth, there is an increased risk that the object will get into trachea or airways accidentally. Choking is also caused by crushing of the trachea. It is also caused by obstruction of airways which can lead to obstructive sleep apnea. Some infections can also cause swelling of the airways or produce excessive secretions.
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 can keep a person alive for several minutes after breathing stops.
