Asphyxiation is caused by lack of oxygen. It can quickly lead to loss of consciousness, brain injury, or death. Some causes of asphyxiation include drowning, asthma, and choking. Asphyxiation is often caused by accident.

Why is asphyxiation important?

Asphyxia, a potentially catastrophic reduction in the supply of oxygen to the fetus during labor and delivery, is also a major contributor to newborn mortality.

What are the four types of asphyxia?

It is proposed to classify asphyxia in forensic context in four main categories: suffocation, strangulation, mechanical asphyxia, and drowning. Suffocation subdivides in smothering, choking, and confined spaces/entrapment/vitiated atmosphere.
