The term asphyxiation is often mistakenly associated with the strong desire to breathe that occurs if breathing is prevented. This desire is stimulated from increasing levels of carbon dioxide. However, asphyxiant gases may displace carbon dioxide along with oxygen, preventing the victim from feeling short of breath.
Asphyxia or asphyxiation is a condition of deficient supply of oxygen to the body which arises from abnormal breathing. [ 3 ] [ 4 ] Asphyxia causes generalized hypoxia , which affects all the tissues and organs, some more rapidly than others.
Illness resulting from acute exposure is usually not fatal although some exposure may cause bronchiolitis obliterans, pulmonary edema as well as rapid asphyxiation. [40] If the concentration of exposure is excessively high, the gas may displace oxygen resulting in fatal asphyxiation. [41]
Coal, once exposed to the air of a mine, naturally begins absorbing oxygen and exuding carbon dioxide and water vapor. The amount of blackdamp exuded by a mine varies based on a number of factors, including the temperature (coal releases more carbon dioxide in the warmer months), the amount of exposed coal, and the type of coal, although all ...
When trapped in a burning building people often die of asphyxiation because the fire consumes all the oxygen. ... are seen as creeps for doing the exact same thing an attractive person does. #45.
Sulfur hexafluoride is a nontoxic gas, but by displacing oxygen in the lungs, it also carries the risk of asphyxia if too much is inhaled. [53] Since it is more dense than air, a substantial quantity of gas, when released, will settle in low-lying areas and present a significant risk of asphyxiation if the area is entered.
By Jonathan Allen (Reuters) -The Supreme Court of Alabama is weighing whether to allow the state to become the first to execute a prisoner with a novel method: asphyxiation using nitrogen gas.
