WebHigh values indicate an increased oxygen supply (hyperdynamic phase) or decreased tissue demand for oxygen, or more dangerously, an inability of cells to use oxygen (cellular dysoxia). If the cells aren't able to use oxygen, cells may have been "stunned" and are in a minimal use of oxygen phase.
