At Body Temperature and a PaO₂ of 500 MmHg, How

Question

At body temperature and a PaO2of 500 mmHg, how much oxygen can dissolve in the plasma?
A) 1.5 vol%
B) 0.015 vol%
C) 15 vol%
D) 0.15 vol%

Accepted Answer

The solubility of oxygen in plasma is 0.003 ml/100 ml/mmHg. At a PaO2 of 500 mmHg, the amount of oxygen dissolved in the plasma would be 0.003 ml/100 ml * 500 mmHg = 1.5 ml/100 ml, or 1.5 vol%.
