How can asphyxiation cause death?

How can you tell if someone was suffocated?
One of the signs of death by suffocation is the appearance of blood engorgement of the viscera. Congestion is one of the signs of prolonged asphyxia. The visceral veins and capillaries are filled with blood. Because of asphyxia the blood reser- voirs, including the spleen, become empty.

Can an autopsy reveal suffocation?
In most instances, autopsy findings will be minimal. Nonspecific findings may include indentations or ‘pressure marks’ on the skin related to bedding or clothing.
