All of the following would result in lower oxygen saturation of hemoglobin except
A)an increase in $\mathrm { P } _ { \mathrm { O } _ { 2 } }$
B)an increase in temperature
C)an increase in $\mathrm { P } _ { \mathrm { CO } _ { 2 } }$
D)a decrease in pH
E)an increase in DPG

Increased $\mathrm { P } _ { \mathrm { O } _ { 2 } }$ would actually increase oxygen saturation of hemoglobin, so this is the only option that would not result in lower oxygen saturation. B, C, D, and E would all shift the oxygen-hemoglobin dissociation curve to the right, making it harder for hemoglobin to bind to oxygen and thereby lowering oxygen saturation.
