3/18/2013 Summary of Fick Oxygen Method: AV O 2 Difference Step 1: Theoretical oxygen carrying capacity O 2 carrying capacity (mL O 2 / L blood) = 1.36 mL O 2 / gm Hgb x 10 mL/dL x Hgb (gm/dL) Step 2: Determine arterial oxygen content Arterial O 2 content = Arterial saturation x O 2 carrying capacity Step 3: Determine venous oxygen content Mixed venous O 2 content = venous saturation x O 2 carrying capacity Step 3: Determine A-V O 2 oxygen difference AV O 2 difference = Arterial O2 content - venous O 2 content Baim DS: Grossman’s Cardiac Catheterization, Angiography, and Intervention. 7 th Edition.
