The answer is 162.24 atm for partial pressure of helium gas.

Reason: Heloix's atmospheric pressure is p0=atm.

Oxygen mole fraction =Xo=0.22

Helium's mole fraction is xHe=1-Xo=1-0.22=0.78.

Dalton's law of partial pressure states that

Heloix's oxygen partial pressure is calculated as follows: p0=p0Xo=208atm0.22=45.76atm

Heloise's partial pressure of helium is pHe=p0XHe=208atm0.78=162.24atm.

Helium gas has a partial pressure of 162.24 atm.

What happens when oxygen and helium are combined?

The density of heliox, a mixture of helium and oxygen, is lower than that of air. In especially in conditions marked by increased airways resistance, inhaling heliox results in a decrease in resistance to flow within the airways and, as a result, a reduction in the work of breathing (WOB).
