The formula to calculate the Arterial Oxygen Content is:
\[ CaO2 = (Hb \cdot 1.36 \cdot SaO2 / 1000) + (0.0031 \cdot PaO2) \]
Where:
The arterial oxygen content is the amount of oxygen bound to hemoglobin plus the amount of oxygen dissolved in arterial blood.
Let's assume the following values:
Using the formula:
\[ CaO2 = (130 \cdot 1.36 \cdot 95 / 1000) + (0.0031 \cdot 85) \]
Evaluating:
\[ CaO2 = 17.0595 \]
The Arterial Oxygen Content is 17.0595.
