The blood O 2 dissociation curve was determined with a microphotometric reaction apparatus in two frog species, Rana catesbeiana and Rana brevipoda , and formulated in terms of a modified Hill equation. The O 2 dissociation curve was in reasonable agreement with determinations of O 2 content, ...
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 Cao2is thearterial oxygencontent in volume percent. ...
The amount of oxygen dissolved in the plasma can be estimated by the following equation: Dissolved O2 = 0.003 ml O2/100 ml blood/mm Hg PO2 This equation holds true no matter how high the oxygen tension rises (30). This formula should be remembered when oxygen is administered to an ...
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...
Neurons are especially sensitive to hypoxia and may die or be damaged if blood flow and oxygen supplies are not quickly restored. Pulse After blood is ejected from the heart, elastic fibers in the arteries help maintain a high-pressure gradient as they expand to accommodate the blood, then ...
less light can penetrate into deeper blood vessels or tissues, which means fewer sound waves are emitted by the tissue. This in turn makes it difficult to take high resolution images of blood oxygen content in these parts of the body and leads to underreported oxygen levels in deeper blood ve...

Cerebral oxygen transport (total hemispheric flow x arterial oxygen content) fell signifi- cantly (p < 0.001) at each level of hypocarbia. Cerebral oxygen extraction increased with progressive hypocarbia, i.e. (A-V)02 and the percent extraction at each cantly different from the other two ...
1 When fully saturated, a gram of Hb carries about 1.34 mL/dL of oxygen (1 dL = 100 mL). Oxygen content of arterial blood (CaO2 [mL O2/100 mL]) Equation 10–5CaO2=1.34 mL/g×Hb(g/100mL)×SaO2+0.003 PaO2 Equation 10–6SaO2=100×O2Hb/(O2Hb+RHb) The arterial oxygen ...
