 Xenon has a minimum alveolar concentration ( MAC ) of 72 % at age 40 , making it 44 % more potent than N2O as an anesthetic . Thus it can be used in concentrations with oxygen that have a lower risk of hypoxia . Unlike nitrous oxide ( N2O ) , xenon is not a greenhouse gas and so it is also viewed as environmentally friendly . Xenon vented into the atmosphere is being returned to its original source , so no environmental impact is likely .

Xenon got a minimum alveolar concentration ( MAC ) of 72 % at age 40 , makin it 44 % more potent den N2O as an anesthetic . Thus it can be used in concentrations with oxygen got a lower risk of hypoxia . Unlike nitrous oxide ( N2O ) , xenon ain't greenhouse no gas and so it is also viewed as environmentally friendly . Xenon vented into da atmosphere is being returned to its original source , soo no environmental impact likely .
