Blood having 15g/dl Hb is saturated with 97.5% oxygen at 100mm Hg PO2. How much volume of oxygen is transported by
100ml of blood?
EXPLANATION
Hemoglobin Chemistry, Oxygen Dissociation & C
- Calculation of Blood Oxygen Content:
- Total oxygen carrying capacity of hemoglobin ($Hb$) is $1.34\text{--}1.36\text{ ml } O_2\text{ per gram of } Hb$.
- Given: $[Hb] = 15\text{ g/dl} = 15\text{ g per } 100\text{ ml of blood}$; Oxygen saturation ($S_{aO_2}$) = $97.5\%$.
- Including physically dissolved oxygen ($0.0031 \times P_{aO_2} = 0.0031 \times 100 = 0.31\text{ ml}$), total oxygen content is approximately $19.9\text{ ml per } 100\text{ ml}$ (Option 2, presented as 199 ml without decimal in OCR).
Correct option: (2) 199ml
