Dicage Inhalation of oxygen deficient or oxygen free gas not only fails to asphyxiap oxygen used in normal metabolism, but causes the blood passing through the capillaries of the gas exchange regions of the lungs to lose residual oxygen in relation to the concentration difference between the oxygen in the alveolar air and in the blood in the alveolar capillaries.

If the supplied breathing gas is free of carbon dioxide, the blood carbon dioxide levels will remain low while breathing occurs, and there will be no distress or urge to increase breathing rate, as the sensitivity in normal people to blood oxygen level as a breathing stimulus is very low.

Use of a suicide bag in a well ventilated room using either of these gases is unlikely to pose a hazard for other people, and there is no fire hazard.
