What is the formula for oxygen delivery?

Equation 1 Oxygen delivery index (DO2I) calculation formula (normal range 520-720 ml O2/min/m2). DO2I = O2 delivery index = DO2 mls/min/m2 = (10 × Hb/dl × 1.34 × SpO2) + (PaO2 in mmHg × 0.003 × 10) × Cardiac index l/min/m2.

What is normal oxygen delivery?

Global oxygen delivery describes the amount of oxygen delivered to the tissues in each minute and is a product of the cardiac output and arterial oxygen content. With a resting cardiac output of 5 litre min−1 (and using the same figures as before), a ‘normal’ adult male has an oxygen delivery of 997.5 ml min−1.

What is normal C AV O2?

C(a-v)O2. • = CaO2 – CvO2. • Oxygen extracted by tissues from each 100 ml. arterial blood. • Normal – 5 vol%

What is PA O2?

An ABG measures: Partial pressure of oxygen (PaO2). This measures the pressure of oxygen dissolved in the blood and how well oxygen is able to move from the airspace of the lungs into the blood.

How is oxygen delivery calculated in a calculator?

This oxygen delivery calculator computes the product between the arterial oxygen content (CaO 2) and cardiac output (CO), which is the amount of oxygen delivered to the capillaries per minute, also known as oxygen delivery (DO 2 ). 1. Oxygen delivery calculator 2. Oxygen delivery explained

How is oxygen expressed in ML O 2 / min?

It is the product of total blood flow or cardiac output (CO) and the oxygen content of arterial blood and is usually expressed in ml O 2 /min. From oxygen in the environment to feeding the tissues, the process has three steps: oxygenation, oxygen delivery and oxygen consumption.

How does a unit 4 oxygen delivery device work?

1. Attach the appropriate oxygen diluter to the 6” flex tube. 2. Attach the connecting tubing to the venturi device and oxygen source. 3. Attach the oxygen analyzer to the 6” flex tube. 4. Adjust flowmeter to prescribed setting. 5. Analyze and record FIO2. Predicted FIO2O2flow (L/min.) Measured FIO2O2 flow (L/min.) Measured FIO2

How much oxygen is delivered to the periphery?

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.
