Delivery of oxygen can be calculated with the equation: DO 2 = CO x CaO 2. Where CaO 2 = [1.34 x Hgb x SaO 2] + [PaO 2 x 0.003] . The portion contributed by dissolved O 2 [PaO2 x 0.003] is usually negligible except in cases of extreme anemia (i.e. Hgb 5) or carbon monoxide poisoning.. Factors that affect the oxyhemoglobin dissociation curve will also affect oxygen delivery:

May 17, 2016 · Notwithstanding these comments, we will continue with oxygen delivery within the context of this article in order to remain consistent with common custom and usage. Global oxygen delivery describes the amount of oxygen delivered to the tissues in each minute and is a product of the cardiac output and arterial oxygen content.Author: J-Oc Dunn, MG Mythen, MP Grocott, MP Grocott

Oxygen delivery to tissues. Samsel RW(1), Schumacker PT. Author information: (1)Section of Pulmonary and Critical Care Medicine, University of Chicago, Illinois. For health, well perfused tissues, oxygen uptake is determined primarily by metabolic need rather than by oxygen supply.Author: R. W. Samsel, P. T. Schumacker

OXYGEN DELIVERY TO TISSUES 1259 and keeping the intercapillary spacing close enough (3). For the normal circulation, the maintenance of an adequate Po 2 depends largely on convective oxygen transport accomplished by the heart, lungs and blood [4]. The tissue Po 2, and even the capillary Po 2, cannotAuthor: R. W. Samsel, P. T. Schumacker

abstract = "For health, well perfused tissues, oxygen uptake is determined primarily by metabolic need rather than by oxygen supply. Tissue hypoxia supervenes when tissue oxygen tension (PO2) falls below a critical point, and the point where this occurs can be predicted from the systemic oxygen delivery or …Author: R. W.

Oxygen Delivery. Since limited amount of oxygen is stored in the body, the cells depend upon continuous supply of oxygen by blood. The oxygen delivered per minute to cells is roughly 4 times the oxygen consumption. Oxygen delivery (DO 2) refers to the amount of …Author: Sumesh Arora, Pratik Tantia

An animal model for evaluating oxygen delivery to tissue is based upon the determination of the intracellular oxygen tension by surface fluorometry of NADH under conditions where the inspired oxygen is reduced through the critical value for the particular organ.Author: Britton Chance, Avraham Mayevsky, Cleon Goodwin, Leena Mela

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.
