Suffocation is the process of Asphyxia. The hypoxemia and acidosis caused by asphyxia in drowning affect various organs. Common causes of early neonatal mortality are bacteria infection, fetal asphyxia and fading puppy syndrome. Inhaling butane gas can cause drowsiness, unconsciousness, asphyxia, and cardiac arrhythmia. Accordingly, death resulted primarily from hypovolemic shock and exhaustion asphyxia. Fetal death can be caused by asphyxia. Both of these lead to autoerotic asphyxia. The two complications of particular interest are intranatal asphyxia and neonatal jaundice. All of them had live birth pregnancies and no severe neonatal asphyxia was observed. Unconsciousness in cases of accidental asphyxia can occur within 1 minute. Many died due to asphyxia, starvation or dysentery. Pythons, anacondas, and other constrictor snakes kill through compressive asphyxia. Hazards include flammability after vaporization into a gaseous state, freezing and asphyxia. The cause of death was ruled to be positional asphyxia. There is considerable controversy over the diagnosis of birth asphyxia due to medicolegal reasons.
