Heliox is a breathing gas mixture of helium (He) and oxygen (O 2).It is used as a medical treatment for patients with difficulty breathing because this mixture generates less resistance than atmospheric air when passing through the airways of the lungs, and thus requires less effort by a patient to breathe in and out of the lungs.
An example of this would be breathing air in a heliox environment. The helium in the heliox diffuses into the skin quickly, while the nitrogen diffuses more slowly from the capillaries to the skin and out of the body. The resulting effect generates supersaturation in certain sites of the superficial tissues and the formation of inert gas ...
In medicine, Heliox generally refers to a mixture of 21% O 2 (the same as air) and 79% He, although other combinations are available. Heliox generates less airway resistance than air and thereby requires less mechanical energy to ventilate the lungs. [9] "Work of Breathing" is reduced. It does this by two mechanisms: increased tendency to ...
Not only has life expectancy not surpassed 85 in nearly any county, the U.S. famously saw a decline in life expectancy, and in 2023, it was the lowest it’s been in two decades (though Harvard ...

Saturation diver working on the USS Monitor wreck at 70 m (230 ft) depth. Saturation diver conducts deep sea salvage operations. Saturation diving is diving for periods long enough to bring all tissues into equilibrium with the partial pressures of the inert components of the breathing gas used.
The Centers for Disease Control and Prevention reports that the average life expectancy in the U.S. is about 77.5 years as of their most recent mortality report in 2022. However, averages can be ...
