Pronunciation: as-'fik-sE-&, &s-
Function: noun
Etymology: New Latin, from Greek, stopping of the pulse, from a- + sphyzein to throb
: a lack of oxygen or excess of carbon dioxide in the body that results in unconsciousness and often death and is usually caused by interruption of breathing or inadequate oxygen supply

Asphyxia (from Greek a-, "without" and sphuxis, "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. Sometimes there is not enough carbon dioxide to cause air hunger, and victims become hypoxic without knowing it. In any case, the absence of effective remedial action will very rapidly lead to unconsciousness, brain damage and death. The time to death is dependent on the particular mechanism of asphyxia. In an experiment where dogs were suffocated by placing an air-tight rubber mask over the dogs' heads, it was shown that it took around 8 minutes for the dogs to go into cardiac arrest. Breathing movements continued and the animals engaged in violent struggle or had convulsions until the point of death.[1] This can be contrasted with another experiment in which dogs were suffocated by forcing them to breathe nitrogen and on average survived only 5 minutes. The reason is considered to be loss of oxygen into the environment when the animals were able to breathe freely.[1] The constriction of the arteries and/or veins in the neck, such as in certain types of strangulations, do not cause asphyxia but rather cerebral ischemia (local asphyxia[citation needed]). Asphyxiation or suffocation refer to the process of asphyxia, where the body becomes increasingly hypoxic.
Asphyxia is used to maim or kill in capital punishment, suicide, torture, and warfare. It is also used non-fatally in martial arts, combat sports, BDSM and during sex as ****** asphyxia. Because the need to breathe is triggered by the level of carbon dioxide in the blood, some victims may not experience an urgent need to breathe and may remain unaware of the onset of hypoxia.

asphyxiation. the airways get obstructed or constricted restricting air flow to the lungs.
