Positional asphyxia

Inability to breathe due to body position or posture

Positional asphyxia, also known as postural asphyxia, is a form of asphyxia which occurs when someone's position prevents the person from breathing adequately. People may die from positional asphyxia accidentally, when the mouth and nose are blocked, or where the chest may be unable to fully expand.
