Aug 01, 2004 · Increased oxygen extraction by the tissues occurs during anaemia by improved matching of oxygen delivery to oxygen demand. There is a redistribution of blood flow to areas of high demand, such as the myocardium and the brain. In the microcirculation a number of mechanisms help to maintain tissue oxygenation.Author: S. A. McLellan, T. S. Walsh

oxygen delivery is therefore central to the man-agement of patients during anaesthesia, resus-citation and during critical illness. This review deals specifically with the transport of oxygen from the lungs to non-pulmonary tissues. Definitions Oxygen delivery Global oxygen delivery (D_ O2) is the amount of oxygen delivered to the whole body ...

Therefore, oxygen delivery can be affected by changes in cardiac output as well as changes in the oxygen saturation of hemoglobin, the amount of hemoglobin available, and to a much smaller extent the PaO2 (the amount of oxygen dissolved in the blood).
https://www.openanesthesia.org/peripheral_oxygen_delivery/
Peripheral oxygen delivery. Definition. Components of Oxygen in Blood. Oxygen delivery to the periphery depends on the oxygen content of blood and tissue blood flow. The oxygen content of blood has two components: oxygen bound to hemoglobin and oxygen dissolved in plasma. Oxygen bound to hemoglobin is generally the much greater contributor to ...

Cooperativity Enhances Oxygen Delivery by Hemoglobin. Because of cooperativity between O 2-binding sites, hemoglobin delivers more O 2 to tissues than would a noncooperative protein (pO 2, partial pressure of oxygen.) 10.2.1. Oxygen Binding Induces Substantial Structural Changes at the Iron Sites in Hemoglobin.Author: Jeremy M Berg, John L Tymoczko, Lubert Stryer

The oxygen is then transported from the lungs to the peripheral tissues, where it is removed from the blood and used to fuel aerobic cellular metabolism. This process can be conceptualized as three steps: oxygenation, oxygen delivery, and oxygen consumption. In this topic review, oxygen delivery and consumption are reviewed.
