title: Tissue oxygenation: another aspect of the Fick equation.
abstract: Substituting the formulas of O2 delivery (DO2) and O2 extraction ratio (O2ER) into the Fick equation, a new equation representing tissue oxygenation is obtained: VO2 = DO2 X O2ER. This aspect of the Fick equation is important in clinical practice as it provides a reliable picture of tissue oxygenation if all related variables are examined together.
