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.

Using the oxygen content equation and a hemoglobin concentration of 15 g/dL the amount of oxygen this blood caries is 21.14 mL/dL. 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.

Owing to the decreased CO and LV perfusion, systemic and coronary O2 delivery fell by 4 and 11% at 8 l of O2/min, despite the increased blood oxygen content. CONCLUSION: Our data indicate that O2 administration decreases CO, LV perfusion and systemic and coronary O2 delivery in healthy individuals.Author: Stefan Bodetoft, Marcus Carlsson, Håkan Arheden, Ulf Ekelund

Mar 26, 2017 · These patients will rely more on the partial pressure of oxygen (PaO2) to augment their overall O2 content until a red cell transfusion is performed. Once the CaO2 is optimized, now it’s a matter of optimizing the patient’s cardiac output (CO) to facilitate oxygen delivery.

correct: O2 delivery is impacted cardiac output correct: SvO2 and ScvO2 represent venous O2 return to the heart. A nurse administers an ACE inhibitor to a patient with left ventricular failure and BP 92/60 (71). What is the likely end result.???? SVR decreases; preload, CO, and BP increase
