Accordingly, the human subject detects little abnormal sensation as the oxygen level falls. Physiologically inert gases (those that have no toxic effect, but merely dilute oxygen) are generally free of odor and taste. When humans breathe in an asphyxiant gas, such as pure nitrogen, helium, neon, argon, methane, or any other physiologically inert gas(es), they exhale carbon dioxide without re-supplying oxygen. 3.1 Relation to controlled atmosphere killing.Nitrogen asphyxiation has been approved in some places as a method of capital punishment, but has not yet been used for this purpose. Inert gas asphyxia has been advocated by proponents of euthanasia, using a gas-retaining plastic hood device colloquially referred to as a suicide bag. Īn occasional cause of accidental death in humans, inert gas asphyxia with gases including helium, nitrogen, methane and argon has been used as a suicide method. Hazards with inert gases and the risks of asphyxiation are well established. The exposed person has no warning and cannot sense that the oxygen level is too low." In the US, at least 80 people died from accidental nitrogen asphyxiation between 19. Chemical Safety and Hazard Investigation Board, in humans, "breathing an oxygen deficient atmosphere can have serious and immediate effects, including unconsciousness after only one or two breaths. Instead, the gas acts as a simple diluent to reduce oxygen concentration in inspired gas and blood to dangerously low levels, thereby eventually depriving all cells in the body of oxygen. The term "physiologically inert" is used to indicate a gas which has no toxic or anesthetic properties and does not act upon the heart or hemoglobin. Examples of physiologically inert gases, which have caused accidental or deliberate death by this mechanism, are argon, helium, nitrogen and methane. Inert gas asphyxiation is a form of asphyxiation which results from breathing a physiologically inert gas in the absence of oxygen, or a low amount of oxygen, rather than atmospheric air (which is composed largely of nitrogen and oxygen). ![]()
