In 1756, Black proved that carbon dioxide (which was then called "fixed air") occurred in the atmosphere and that it could form other compounds. He also identified carbon dioxide in the breath exhaled by humans. The first practical use of carbon dioxide can be traced to an invention made ...

Carbon dioxide (CO2), a natural product of human metabolism, accumulates quickly in sealed environments when humans are present, and can induce headaches, among other symptoms. Major resources are expended to control CO2 levels to concentrations that are tolerable to the crews of spacecraft and ...
Carbon Dioxide Absorption In partialrebreathingand nonrebreathing systems, carbon dioxide is vented to room air. When a closed system is used, however, the exhaled carbon dioxide must be otherwise removed. Carbon dioxide in the presence of water is hydrated to form carbonic acid. When carbonic aci...
CaCO3). He called it “fixed air”. He also identified it from exhaled breath and described it as denser than the air faintly acidic. In 1803,John Dalton(English chemist) proposed that this substance is comprised of one carbon atom and two oxygen atoms. Now, it is called“carbon dioxide...

In humans and experimental animals, CCl4 is rapidly eliminated by passive diffusion primarily through exhaled breath, with a smaller fraction eliminated in urine and feces (IARC, 1979). The free radicals generated by CCl4 metabolism attack polyunsaturated fatty acids in cell membranes forming fatty ...
Oxygen inhalation should just drive away the exhaled high concentration of carbon dioxide and play a role. This method can obviously eliminate sleep drunkness/non-alcoholic drunkness/brain fog (the effect is still limited), and the pure stimulation of espresso feels equivalent to short-term arousal...
