Positional asphyxia, also known as postural asphyxia, is a form of asphyxia which occurs when someone's position prevents them from breathing adequately.
- Positional asphyxia is a potential danger of many physical restraint techniques, and of some sexual bondage techniques.
- People may die from positional asphyxia by simply getting themselves into a breathing-restricted position they cannot get out of, either though carelessness or as a consequence of another accident.
- Small children under two are particularly at risk from positional asphyxia.
