Oxygen binds to hemoglobin in the lungs, nearly saturating it, and desorbs in the tissue but only partially deoxygenating the blood. Oxygen delivery to the tissues is calculated as the cardiac output times the arteriovenous difference in total oxygen content of the blood. The oxygen consumption ...
The monitoring of oxygenation in the fetus or newborn demands a reliable way of estimating the oxygen content of blood. Although it is generally accepted that Pao2 monitoring is the gold standard surrogate of tissue oxygenation in preterm infants, there is no clinical evidence to date to support...
I n this regard, the technique was the same as that reported previously [8, 121. The methods used for calculation of oxygen content and oxygen transfer rates have also been described [8, 121. blood p 0 2during all 28 experiments have been report- ed [I]. I t was possible to produce...
Of these three values, PaO2, oroxygen pressure, is the least helpful to answer the question about oxygen adequacy in the blood. The other two values --oxygen saturationandoxygen content-- are more useful for this purpose. I will briefly define these three terms and then present a more detai...

Production of energy relies on the coordinated functions of the cardiovascular, pulmonary, and musculoskeletal systems to provide oxygenated blood to central and peripheral structures for energy metabolism. Regulation by the autonomic nervous system (ANS) oversees these processes to ensure that oxygen dema...
Measurements of oxygen concentration versus PO2 in blood from 33 normal adults were fitted, using a special nonlinear regression analysis, to the Hill equation to obtain the parameters describing the position (P50) and shape (n) of each oxygen-hemoglobin equilibrium curve (OHEC). Data between 20...
A method for studying oxygen diffusion barrier in erythrocytes: The effects of haemoglobin content and membrane cholesterol. J. Physiol. 1980; 309: 569-90.Kon, K., Maeda, N., Sekiya, M., Shiga, T., and Suda, T. A method for studying oxygen diffusion barrier in erythrocytes; effects of...
The oxygen content of the blood relates to the ability of haemoglobin to combine with oxygen. As one gram of haemoglobin can combine with 1.34 ml of oxygen, the normal content of arterial blood should be 20 ml of oxygen per 100 ml of blood. But as the blood is rarely 100% saturated th...
The resulting concentrated LOM suspension preferably has an oxygen content ranging from 50 to 99% (vol). Prior to administration to a patient, the viscosity of the LOM suspension may be reduced to the desired viscosity, preferably similar to the viscosity of the patient's blood. The resulting ...
