Objectives: To measure the extent of dilution of helium-oxygen (heliox) by room air when given via high concentration reservoir mask to spontaneously breathing subjects. Substantial dilution of heliox by room air under these circumstances might alter its physical properties sufficiently to negate any potential clinical benefit in obstructive respiratory failure.
Design: Healthy volunteers breathing different concentrations of helium in oxygen via two different masks in a randomised crossover design.
