Heliuox 20/80 diffuses 1.8 times faster than oxygen, and the flow of heliox20/80 from an oxygen flowmeter is 1.8 times the normal flow for oxygen. Heliox has a similar viscosity to air but a significantly lower density (0.5 g/L versus 1.25 g/L at STP). Flow of gas through the airway comprises laminar flow, transitional … Meer weergeven Heliox is a breathing gas mixture of helium (He) and oxygen (O2). It is used as a medical treatment for patients with difficulty breathing because mixture generates less resistance than atmospheric … Meer weergeven In medicine heliox may refer to a mixture of 21% O2 (the same as air) and 79% He, although other combinations are available (70/30 and 60/40).
