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.
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.
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 ...
Nitrogen dioxide poisoning disrupts the balance of reactive oxygen species (ROS), which results in oxidative stress, leading to significant effects on the female reproductive lifespan. ROS play a significant role in body physiology, from oocyte production, development and maturation to fertilization, development of the embryo and gestation.
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.

Atmospheric effects generated using water and dry ice or liquid nitrogen can present asphyxiation or breathing hazards. Both carbon dioxide and nitrogen displace ordinary air and the oxygen it contains, creating a risk of subtle anoxia (lack of oxygenation) for people working in these atmospheres. Adequate ventilation is essential to ensure ...
