Asphyxiation is a condition of severe oxygen deprivation that can lead to unconsciousness or death. Common causes of asphyxiation include choking, suffocation, and strangulation.
Choking
Choking is a form of asphyxiation caused by an obstruction of the airways. This can be caused by eating or drinking a foreign object or a piece of food that is too large. It can also be caused by a collapsed lung or a tumor blocking the airways.
Suffocation
Suffocation is caused by a lack of air, usually by blocking the airways. Examples of objects that can cause suffocation include a pillow, a plastic bag, or a mattress. It can also occur when a person is unable to move and is unable to get air.
Strangulation
Strangulation is a form of asphyxiation caused by pressure on the neck. This can be caused by a person using their hands to strangle another person, or by a ligature such as a rope or a scarf. Strangulation can also be caused by a collar or a noose.
