O2 Uptake, Exercise & Cor. Circ., Dr. D. Penney



Ischemia

Increased A-V O2 diff. at rest usually indicates ischemia.

Ischemia is relieved by:

  • increasing blood flow
  • decreasing O2 consumption

    Increased A-V lactate indicates inadequate flow; heart usually uses lactate, in ischemia it produces lactate.
