  • It means that one is suffocating, or, in other words, can't breath. While choking can cause it, choking is not "asphyxiation".
  • No, these are two different things: 1) "Asphyxia (from Greek a-, "without" and sexuxis, "pulse, heartbeat") is a condition of severely deficient supply of oxygen to the body that arises from being unable to breathe normally. Asphyxia causes generalized hypoxia, which primarily affects the tissues and organs most sensitive to hypoxia first, such as the brain, hence resulting in cerebral hypoxia. Asphyxia is usually characterized by air hunger but this is not always the case; the urge to breathe is triggered by rising carbon dioxide levels in the blood rather than diminishing oxygen levels." "Asphyxiation or suffocation refer to the process of asphyxia, where the body becomes increasingly hypoxic." Source and further information: http://en.wikipedia.org/wiki/Asphyxiation 2) Choking has various meanings: - "Choking is the mechanical obstruction of the flow of air from the environment into the lungs. Choking prevents breathing, and can be partial or complete, with partial choking allowing some, although inadequate, flow of air into the lungs. Prolonged or complete choking results in asphyxiation which leads to hypoxia and is potentially fatal. Choking can be caused by: #Introduction of a foreign object into the airway, which becomes lodged in the pharynx, larynx or trachea. #Respiratory diseases that involve obstruction of the airway. #Compression of the laryngopharynx, larynx or trachea in strangles." Source and further information: http://en.wikipedia.org/wiki/Choking - choking meaning compression of the neck, see Strangling: "Strangling is compression of the neck that leads to unconsciousness or death by causing an increasingly hypoxic state in the brain." http://en.wikipedia.org/wiki/Strangling - some other meaning having to do with the various meanings of "choke": http://en.wikipedia.org/wiki/Choke 3) this was the long answer. A very good short answer, which brings that to the point, was already given by "Patrick_McCallister_The Departed". I am just giving some supplementary information.
