can someone explain if the results are normal

Explanation / Answer
3. Dissolved O2 value = PO2 x Solubility
The question stated tht PaO2 and PAO2 are normal therefore, the PO2 value is 100 mmHg (12.5kPA). the solubility of oxygen in blood is 0.3%.
Therefore, Dissolved O2 value
= 100 x (0.003 mlO2/ dL)
= 0.3 mlO2/ dL
4. Ttoal O2 content= Dissolved O2+ O2 content
= 0.3 mlO2/ dL+ 10.29 mlO2/dL
= 10.59 mlO2/dL
The above values of total O2 content is not normal. The normal content should equal or more than 20.6 ml/dL.If value is less than 50% of normal values, then the person is in hypoxia condition.
