Strangulation and Suffocation

Recommendations

Info

Injury in Suffocation • Many cases will have no injury. • If the victim is impaired by severe natural disease, or intoxicated, or physically restrained, then suffocation may leave no physical marks. • If there are no teeth, then the telltale lip injuries are not likely. • Suffocation done with a medical device, like obstruction of an endotracheal tube or turning off a ventilator leaves no findings.

The Medical Process • Temporary obstruction of the carotid arteries, or the jugular veins (strangulation), or the airway (suffocation) • Produces ASPHYXIATION -- an interruption of oxygenation (c) Dean Hawley and Candace Heisler, 2012 17
