In the Plateau Region of the Hb-O? Curve, a Large $\mathrm { P } _ { \mathrm { O } _ { 2 } }$

True/False

In the plateau region of the Hb-O? curve, a large decrease in $\mathrm { P } _ { \mathrm { O } _ { 2 } }$ results in a small decrease in Hb saturation, whereas in the steep portion of the curve, a small decrease in $\mathrm { P } _ { \mathrm { O } _ { 2 } }$ results in a large decrease in percent Hb saturation.
