  • PHYSICS: Calculating a Partial Pressure – (ALST)

    ‹PHYSICS: Gas Co...
    PHYSICS: Calcul...›

    • Calculating a Partial Pressure and maintaining a Partial Pressure of oxygen is essential in Life Support.

    • ALST Calculating a Partial Pressure

      To Establishing a Partial Pressure use % x AP ÷ 100 (Daltons Law)

      A diver at a depth of 80 msw breathes a 8/92 heliox mix. What is the ppO2?

      Absolute Pressure at 80 msw = 9 bar(a) Humans are always involved… so Pressure will always be absolute

      Therefore Partial Pressure = 8% x 9b(a) ÷ 100 = 0.720 bar(a)

      Very often we express pp in millibars. To find the mbar multiply the bar by 1000

      = 0.72 bar(a) x 1000 = 720 mbar
