Given the following blood parameters, compute the total oxygen content (dissolved + HbO₂) of the blood in ml/dl: Hb = 18; PO₂ = 40 mm Hg; SO₂ = 73%.

The total oxygen content of the blood can be calculated using the formula: $$ \text{Oxygen content} = (\text{Hb} \times 1.34 \times \text{SO}_2) + (\text{PO}_2 \times 0.003) $$ Given: Hb = 18 g/dl, SO2 = 73%, and PO2 = 40 mm Hg. Plugging these values into the formula: $$ \text{Oxygen content} = (18 \times 1.34 \times 0.73) + (40 \times 0.003) $$ $$ \text{Oxygen content} = (17.7) + (0.12) $$ $$ \text{Oxygen content} = 17.82 $$ Rounding to one decimal place gives 17.7 ml/dl.
