Excerpt

The hypothesis was that anemia, independently of hemodynamic stability, affects tissue oxygenation saturation (StO2) and the deoxygenation rate during stagnant ischemia. The blood hemoglobin concentration is determinant of oxygen delivery. In anemic patients, oxygen delivery decreases and oxygen extraction is increased. This leads to decreased venous hemoglobin saturation and a lower tissue oxygen saturation. The rate of tissue deoxygenation during ischemia is dependent on oxygen consumption and on the amount of oxygen available in the tissue [1]. …
