Heliox

The dolphin, which had been trained for the study, was given a mixture of 80 per cent helium and 20 per cent oxygen known as heliox through a US Navy Fenzy breather, which was placed over its blowhole. ❋ Wired UK (2011)

Nitrox and heliox, Gideon knew, were air mixtures intended for use at great depth or during extended dives in order to alleviate the various problems, including the bends, oxygen toxicity, and nitrogen narcosis, that came as the result of gases being compressed—or decompressed—in the human body. ❋ Howard Gordon (2011)

If a patient is in a heliox atmosphere long enough, he can “freeze” to death even near room temperature, if he is not properly bundled up. ❋ Unknown (2008)

This is why heliox has such a low oxygen concentration (much lower than the 21% of standard air). ❋ Unknown (2008)

One made her presence known soon after they disembarked, pausing only long enough to exchange a few words with the massive Chirinaldo as it was recharging its heliox-breather. ❋ Foster, Alan Dean, 1946- (1991)

There were many reasons why this was so, not the least of them being that the presence of an oxynitro atmosphere was not necessarily a prerequisite for the development of intelligence, the heliox-breathing Chirinaldo being the most prominent exception to the usual but far from absolute atmospheric rule. ❋ Foster, Alan Dean, 1946- (1991)

As for the Chirinaldo, one could never be certain what the massive heliox-breathers were thinking, except that their easygoing society was anything but combative in nature. ❋ Foster, Alan Dean, 1946- (1991)

Besides the Massood, only the Chirinaldo made decent soldiers, and those dizzy heliox-breathers were poor companions on a blasted battlefield. ❋ Foster, Alan Dean, 1946- (1991)

Since the depth's only ninety meters, we sent down a diver, in standard heliox gear. ❋ Clarke, Arthur C. (1990)

A man could be comfortable here with no more equipment than a breathing mask and the right grade of heliox mixture. ❋ Clarke, Arthur C. (1988)

The hypothesis was that the pitch of the whistles would change as the sound speed in heliox is 1.74 times higher than in air - the dolphin would exhibit the same effect that helium has on humans. ❋ Wired UK (2011)

During an acute asthma attack, a patient may be given oxygen or heliox in combination with pharmacologic therapies. ❋ Unknown (2008)

This closed system design allows for delivery of high levels of oxygen or heliox gas mixtures. ❋ Unknown (2008)

The Neb-U-Mask addresses this unmet clinical need by allowing the concurrent delivery of aerosolized medications and high concentrations of oxygen or heliox. ❋ Unknown (2008)

“I’ve already started switching you to heliox,” Big Al said. ❋ Howard Gordon (2011)
