Carbon dioxide is the lasing medium in a carbon-dioxide laser, which is one of the earliest type of lasers. Carbon dioxide can be used as a means of controlling the pH of swimming pools, [139] by continuously adding gas to the water, thus keeping the pH from rising. Among the advantages of this is the avoidance of handling (more hazardous) acids.
Many people with chronic obstructive pulmonary disease have a low partial pressure of oxygen in the blood and high partial pressure of carbon dioxide.Treatment with supplemental oxygen may improve their well-being; alternatively, in some this can lead to the adverse effect of elevating the carbon dioxide content in the blood (hypercapnia) to levels that may become toxic.
Carbon dioxide is a gaseous product of the body's metabolism and is normally expelled through the lungs. Carbon dioxide may accumulate in any condition that causes hypoventilation, a reduction of alveolar ventilation (the clearance of air from the small sacs of the lung where gas exchange takes place) as well as resulting from inhalation of CO 2.
The early-2024 rise in carbon dioxide concentrations was the highest in history, and the increase from 2022 to 2024 may have been the largest two-year jump in the May carbon dioxide peak ever ...
Carbon dioxide is produced continuously as the body's cells respire, and this CO 2 will accumulate rapidly if the lungs do not adequately expel it through alveolar ventilation. Alveolar hypoventilation thus leads to an increased Pa CO 2 (a condition called hypercapnia ).
Hyperoxia can also indirectly cause carbon dioxide narcosis in patients with lung ailments such as chronic obstructive pulmonary disease or with central respiratory depression. [16] Hyperventilation of atmospheric air at atmospheric pressures does not cause oxygen toxicity, because sea-level air has a partial pressure of oxygen of 0.21 bar (21 ...
A $1 billion project to harness carbon dioxide emissions from a Texas coal plant, for example, had chronic mechanical problems and routinely missed its targets before it was shut down in 2020 ...
Different fossil fuels emit different gases, including carbon dioxide, methane, nitrous oxide, some fluorinated gases and others, into the atmosphere. But the gas that is emitted most often is ...
