If cardiac output is 5 L/min, then total oxygen delivery is 1057 mL/min. This blood then travels to the periphery where the PO2 is 40 mmHg. From the oxyhemoglobin dissociation curve, it is evident that a PO2 of 40 is equal to an oxygen saturation of 75%. Using the equation for oxygen content again, the amount of oxygen in venous blood is 15.76 ...

O2 delivery vs. PaO2. Definition. Oxygen delivery is defined as the amount of oxygen delivered to the capillaries per minute. It is calculated by the following formula: DO2=CO x CaO2 (mL/min/m2) So oxygen delivery is dependent on cardiac output as well as the arterial oxygen content.

Jan 21, 2016 · The equation usually used to describe the rate of oxygen delivery is as follows: This equation will not be applicable when levels of dys-hemoglobins (e.g. metHb, carboxyHb, etc) are high. A better formula to describe DO2, taking into account only the concentration of effective Hb would be:

Apr 09, 2019 · Oxygen extraction ratio (O2ER) is the ratio of oxygen consumption (VO2) to oxygen delivery (DO2) global oxygen delivery (DO2) is the total amount of oxygen delivered to the tissues per minute, irrespective of the distribution of blood flow; oxygen consumption (VO2) is the total amount of oxygen removed from the blood due to tissue oxidative ...

The oxygen is then transported from the lungs to the peripheral tissues, where it is removed from the blood and used to fuel aerobic cellular metabolism. This process can be conceptualized as three steps: oxygenation, oxygen delivery, and oxygen consumption. In this topic review, oxygen delivery and consumption are reviewed.

Oxygen Delivery - DO 2. The prime function of the circulation is to deliver oxygen and nutrients to the tissues and to remove waste products from them. If we know the cardiac output and the patient's haemoglobin level and oxygen saturation, then we can calculate one further critical value in hemodynamics - the oxygen delivery to the body or DO2.

Mar 26, 2017 · [Hb] is the hemoglobin concentration, SpO2 is the arterial oxygen saturation (as a decimal), PaO2 is the partial pressure of oxygen in the blood. It’s important to consider acute changes (ie, hemorrhage and desaturation) in the context of this equation. As shown, a patient could easily saturate at 100%… but only have a hemoglobin of 4 g/dL.
https://www.respcalc.com/arterial-oxygen-content/
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.
