"In most cases, death by hanging is caused by brain ischaemia which develops because of compression on the airways and blood vessels of the neck and sometimes reflex cardiac arrest occurs due to vagal inhibition created by pressure on the carotid sinus. Occasionally, death may occur as a result of mechanical asphyxia due to obstruction of the airways with the swallowing of the glottis and tongue directly into the pharynx caused by restriction of the neck. However, these mechanisms of hanging should not be considered separately from each other as it is thought that the inhibition of respiratory and circulatory functions together result in acute brain ischemia leading to death [
