Helium has a higher diffusion coefficient for carbon dioxide relative to oxygen thus promotes exhalation of trapped carbon dioxide. This reduces hypercapnia and normalizes pH. Helium increases the coronary collateral circulation and enhances the vasodilatory effects of inhaled nitric oxide on pulmonary vessels.

Also called inert gas. Helium, chemical element, inert gas of Group 18 (noble gases) of the periodic table. The second lightest element, helium is a colorless, odorless, and tasteless gas that becomes liquid at -268.9 degrees Celsius. The boiling and freezing points of helium are lower than those of any other known substance.

Keep your tone low and soothing. Avoid starting or participating in a conversation that is less than respectful to the family and close friends of the deceased. The noble gases cross the boundary between blocks—helium is an s-element whereas the rest of members are p-elements—which is unusual among the IUPAC groups. Most, if not all [33] other IUPAC groups contain elements from one block each.

Helium är grundämne nummer två i det periodiska systemet, en färglös och luktlös ädelgas. Ämnet har lägst kokpunkt av alla grundämnen, och endast vid högt tryck övergår det i fast form. Helium är det näst vanligaste grundämnet i universum. Nytt helium uppstår genom fusionsprocesser i stjärnorna och genom alfastrålning från radioaktiva grundämnen.

Helium is unique since its valence shell consists of a single s-orbital. The other members of group 8 have a characteristic valence shell electron octet (ns2 +

Inert means that an element is not very active. Any of the six gases helium, neon, argon, krypton, xenon, and radon. Because the outermost electron shell of atoms of these gases is full, they do not react chemically with other substances except under certain special conditions. Also called inert gas.
