[IV C 1; Figure 4.8]. A shift to the right of the hemoglobin $-\mathrm{O}_{2}$ dissociation curve represents decreased affinity of hemoglobin for $\mathrm{O}_{2}$. At any given $\mathrm{Po}_{2}$, the percent saturation is decreased, the $\mathrm{P}_{50}$ is increased (read the $\mathrm{Po}_{2}$ from the graph at $50 \%$ hemoglobin saturation), and unloading of $\mathrm{O}_{2}$ in the tissues is facilitated. The $\mathrm{O}_{2}$-carrying capacity of hemoglobin is the $\mathrm{mL}$ of $\mathrm{O}_{2}$ that can be bound to a gram of hemoglobin at $100 \%$ saturation and is unaffected by the shift from curve A to curve B.
