Total content is hemoglobin-bound plus dissolved oxygen. Bound content=1.34×15×.95=19.095 mL/dL. Dissolved content=.003×40=.120 mL/dL. Sum=19.215 mL/dL=19.215 volume percent, rounded 19.2%. The supplied pressure and saturation are used as given even though they do not represent a usual equilibrium pair on a normal dissociation curve.
