Oxygen Delivery. Therefore, oxygen delivery can be calculated: DO2 = CaO2 x CO. Oxygen Content. Oxygen content can be calculated as: CO2 = (1.39 x Hb x O2Sat/100) + (0.003 x PO2) Oxygen Consumption. Oxygen consumption can be calculated by the Fick principle as the difference between arterial and venous oxygen content: VO2 = CO x (CaO2 – CvO2)

The arterial oxygen content equation: CaO2 = (1.34 * Hb * SaO2) + (0.0031 * PaO2). The normal oxygen combining capacity is 1.39 mls/gram, however due to abnormal forms of hemoglobin such as carboxyhemoglobin and methemoglobin this value is reduced to 1.34 mls/gram.

where SaO 2 is the arterial oxyhemoglobin saturation and PaO 2 is the arterial oxygen tension. In dyshemoglobinemias, the oxygen content is calculated with the same equation, although the saturations (and therefore the oxygen content) will be different for a specific PaO 2 [].Normal CaO 2 is approximately 20 mL O 2 /dL.. Similarly, the mixed venous blood oxygen content (CvO 2) is the amount of ...

So oxygen delivery is dependent on cardiac output as well as the arterial oxygen content. The arterial oxygen content is based on the amount of hemoglobin (Hb), the saturation of hemoglobin with oxygen (SaO2), and the amount of oxygen that each gram of hemoglobin can carry, which has been calculated to be between 1.32 and 1.39, depending on the ...

How does this oxygen content calculator work? This is a health tool anyone can use to determine arterial blood oxygen content based on the hemoglobin value in g/dL, mmol/L or other units, the percentage of Hb oxygen saturation and the arterial oxygen pressure in mmHg, cmH2O or other units.

George E. Karras Jr., in Mechanical Ventilation, 2008. Causes of Arterial Hypoxemia (Decreased Oxygen Tension of Arterial Blood) Arterial blood gas tension is determined by the composition of alveolar gas and the efficiency of gas transfer between the alveoli and the pulmonary capillary blood. Alveolar gas tension is a function of the mixture of inspired gas, the matching of ventilation and ...

Mar 26, 2017 · One of the most important equations in physiology describes the delivery of oxygen to tissues in the body.Naturally, this would be related to the cardiac output (CO) and overall oxygen content in the blood (CaO2). As I wrote about in a previous post, the cardiac output is heavily dependent on a myriad of factors, but the CaO2 is described as follows: ...
