    Oxygen delivery is the amount of oxygen delivered to the peripheral tissue, and is obtained by multiplying the arterial oxygen content (CaO 2) by the cardiac output (Q). For CaO 2 = 20.1 ml/100 ml and Q = 5 l/min: Oxygen delivery (DO 2) = 1005 ml/min

    Oxygen is a non-metallic element existing as a colourless odourless diatomic gas (O 2) in the lower atmosphere and as a triatomic oxygen (O 3) and monatomic oxygen (O) in the upper atmosphere. Joseph Priestley is usually credited with the discovery of oxygen because he was the first to describe it in 1775 in his work entitled Experiments and Observations on Different Kinds of Air.

    Aug 01, 2004 · Oxygen must be transported effectively from the atmosphere to the tissues in order to sustain normal metabolism. An understanding of oxygen delivery is therefore central to the management of patients during anaesthesia, resuscitation and during critical illness.Author: S. A. McLellan, T. S. Walsh

Peripheral oxygen delivery - OpenAnesthesia

    https://www.openanesthesia.org/peripheral_oxygen_delivery/
    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 - OpenAnesthesia

    https://www.openanesthesia.org/o2_delivery_vs-_pao2/
    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.
