Effect of breathing an oxygen-helium mixture under positive pressure on biochemical parameters.

In 35 subjects the effect of breathing an oxygen-helium mixture or oxygen during 10 minutes under positive pressure of 40 hPa was studied. Immediately before positive-pressure breathing, in the last minute of this breathing, and 30 minutes after its and blood samples were taken for investigations.
