restraint asphyxiaJoe Segen2016-12-16T06:44:13+00:00
Restraint asphyxia (RA) is a form of positional asphyxia caused by mechanical–i.e., by a device, or physical–i.e., by a person, restraint which prevents a person’s escape from an asphyxiating position.
The underlying mechanism of RA is unclear; potential causal factors include restriction of thoracic respiratory movements, airway compromise, and release of catecholamines during physical exertion, which occur in normal, healthy volunteers. Autopsy findings to support a diagnosis of RA are meagre to nonexistent, with no typical pathological findings. Determination of RA must be made based on the historical events surrounding the physical struggle.
