Hanging
Medical effects
When cerebral circulation is severely compromised by any mechanism, arterial or venous, death occurs over four or more minutes from cerebral hypoxia, although the heart may continue to beat for some period after the brain can no longer be resuscitated. The time of death in such cases is a matter of convention. In judicial hangings, death is pronounced at cardiac arrest, which may occur at times from several minutes up to 15 minutes or longer after hanging. During suspension, once the prisoner has lapsed into unconsciousness, rippling movements of the body and limbs may occur for some time which are usually attributed to nervous and muscular reflexes. In Britain, it was normal to leave the body suspended for an hour to ensure death.
