Origin of asphyxiaNew Latin from Greek asphuxiā stopping of the pulse a- not ; see a- 1. sphuxis heartbeat ( from sphuzein sphug- to throb )
- The loss of consciousness due to the interruption of breathing and consequent anoxia. Asphyxia can be result from choking, drowning, electric shock, injury.
- The loss of consciousness due to the body's inability to deliver oxygen to its tissues, either by the breathing of air lacking oxygen or by the inability of the blood to carry oxygen. Such asphyxia can be result from the inhalation of non-toxic gases which displace oxygen from the inhaled air, by exposure to carbon monoxide from smoke inhalation such that hemoglobin is poisoned, or the development of methemoglobinemia.
New Latin, from Ancient Greek ἀσφυξία (asphuxia, “stopping of the pulse”): ἀ- (a-, “not”) + σφύξις (sphuxis, “heartbeat”) (from σφυγ-, σφύζω (sphuzō, “I throb”)).
