The amount of oxygen carried from the lungs to tissues by circulating blood (i.e., convective systemic oxygen delivery [DO2]), is given by the equation: where CO is cardiac output in L/min and Cao2 is the arterial oxygen content in volume percent. Oxygen Transport in the Blood CaO2 is...
Oxygen contentOxygen dissociation curveCarbon monoxideOxygen cascadeAlveolar gas equationA-a) oxygen gradientThe partial pressures at the various levels of the oxygen cascade are described here. Emphasis is placed in the application of the Alveolar Gas Equation in this chapter. Hopefully readers will ...
Arterial oxygen content is the sum of oxygen bound to hemoglobin and oxygen carried in physical solution in the blood. From:Equine Anesthesia (Second Edition),2009 About this page Add to MendeleySet alert Chapters and Articles You might find these chapters and articles relevant to this topic. ...
Incidence of retinopathy of prematurity in babies of chronic anaemic mother and after oxygen therapy Physical examination revealed a heart rate of 144 beats/min; blood pressure 53/36 mm Hg; SpO[sub]2 96% on oxygen hood; respiratory rate of 48 breaths/min; and temperature 36.5[degrees]C. Neo...
In the field of blood gas interpretation, confusion about PaO2, SaO2and oxygen content is second only to confusion about mixed acid-base disturbances. Arterial PO2(little 'a')gives us valuable information about adequacy of gas exchange within the lungs, when (and only when) it is subtracted ...
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...

Isotopes, atoms, and molecules. Oxygen has three stable isotopes—16O,17O, and18O—the average content of which constitutes, respectively, 99.759 percent, 0.037 percent, and 0.204 percent of the total number of oxygen atoms on the earth. The predominance of the lightest isotope16O in the iso...
Be able to calculate the dissolved oxygen content of blood from its solubility • Be able to calculate the bound oxygen content of blood from its hemoglobin concentration and oxygen saturation • Write the Hill equation for oxygen binding to hemoglobin • Describe the consequence of positive co...
Thus, as the oxygen content of blood produces changes, we can measure neural activation indirectly. The BOLD signal comes about 6 s after the onset of neuronal firing. The relationship between neural activation and the BOLD fMRI signal is shown in Fig. 3.22. Note that these studies frequently...
