( 2 ) anoxia : Low Hb content ? inability of the blood to carry sufficient O2 to the tissues . Examples : Anaemia , CO poisoning , sulpha - Hb , Met - Hb , chlorates and nitrates . ( 3 ) anoxia : Impaired circulation ? lack of transport of oxygenated blood to the tissues . Examples : CHF , embolism , shock and heat stroke . ( 4 ) anoxia : O2 is freely available in blood but cannot be utilized by the tissues . Example : Cyanide ( A ) , for example high altitude , trapped inside an enclosed space , inhaling irrespirable gases , for example sewer gas , H2 and helium ; ( B ) or : ( i ) CO and cyanide inhibit utilization of O2 at tissue level ; ( ii ) barbiturates , morphine and strychnine paralyses respiratory centre in medulla oblongata ; ( C ) , for example laryngeal spasm / oedema , pulmonary oedema , pneumonia , tumours and abscess . : It is the strangulation caused by holding the neck of the victim in the bend of the elbow . : strangulation in which the assailant , usually from behind and without warning , throws a loop of a ligature ( e . g . rope and wire ) around the neck of the victim and quickly tightens by twisting it tightly with a lever causing sudden loss of consciousness and collapse , leading to death : It is a form of asphyxia in which the air entry into the lungs is prevented by means other than the constriction of neck and drowning is a type of asphyxia caused by mechanical obstruction of external respiratory orifices ( i . e . nose and mouth ) by any means , is a type of asphyxia caused by forceful pushing or thrusting a gag material ( e . g . paper balls , piece of cloth , etc . ) into the mouth , sufficiently deep to block the pharynx . : It is a form of asphyxia ( suffocation ) caused by an obstruction within the air - passages ( especially at or just below vocal cords ) . coronary : It is a condition in which ? a healthy person who begins a meal , suddenly collapses and dies without any further distres s
