Positional asphyxia

Positional asphyxia, also known as postural asphyxia, is a form of asphyxia which occurs when someone's position prevents the person from breathing adequately. Positional asphyxia may be a factor in a significant number of people who die suddenly during restraint by police, prison (corrections) officers or health care staff.〔Reay, D.T. (1996) 'Suspect Restraint and Sudden Death.' Law Enforcement Bulletin. Quantico, Virginia: Federal Bureau of Investigation. (http://www.fbi.gov/publications/leb/1996/may966.txt)〕 Positional asphyxia is also a common cause of death in infants.
* Positional asphyxia is a potential danger of some physical restraint techniques,
* People may die from positional asphyxia by simply getting themselves into a breathing-restricted position they cannot get out of, either through the person's own carelessness, as a consequence of another accident, or where infants are placed in a position where the mouth and nose is blocked, or where the chest may be unable to fully expand.
==Prone restraint==

Research has suggested that restraining a person in a face down position is likely to cause greater restriction of breathing than restraining a person face up.〔Parkes, J. (2002) ‘A Review of the Literature on Positional Asphyxia as a Possible Cause of Sudden Death During Restraint.’ British Journal of Forensic Practice. 4(1) 24–30.〕 Multiple cases have been associated with the hogtie or hobble prone restraint position.〔Reay, D.T., Fligner, C.L., Stilwell, A.D., Arnold, J. (1992) 'Positional Asphyxia During Law Enforcement Transport.' The American Journal of Forensic Medicine and Pathology. 13(2) 90–97.〕〔O'Halloran, R.L., & Frank, J.G. (2000) 'Asphyxial Death During Prone Restraint Revisited: A Report of 21 Cases.' The American Journal of Forensic Medicine and Pathology. 21(1) 39–52.〕 Many law enforcement and health personnel are now taught to avoid restraining people face down or to do so only for a very short period of time.〔
Risk factors which may increase the chance of death include prolonged (particularly resisted) restraint, obesity, prior cardiac or respiratory problems, and the use of illicit drugs such as cocaine. Other issues in the way the subject is restrained can also increase the risk of death, for example kneeling or otherwise placing weight on the subject and particularly any type of restraint hold around the subject's neck. Research measuring the effect of restraint positions on lung function suggests that restraint which involves bending the restrained person or placing body weight on them, has more effect on their breathing than face down positioning alone.〔Parkes, J. & Carson, R. (2008) ‘Sudden Death During Restraint: Do Some Positions Affect Lung Function.’ Medicine, Science and the Law 48(2) 137-41〕
