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.
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, [1] rather than atmospheric air (which is composed largely of nitrogen and oxygen).
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. [55] 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.
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.
(Reuters) -Alabama on Thursday evening plans to carry out the first known judicial execution of a prisoner using asphyxiation with nitrogen gas, a closely watched new method the state hopes to ...
Alabama is poised to use nitrogen gas in a planned execution next month — making it the first of any state to attempt such a method and setting the stage for legal challenges.
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 ...
