The oxygen-hemoglobin saturation curve illustrates the effect of increasing PO2 on the percent saturation of hemoglobin with oxygen.

氧合血红蛋白饱和度曲线说明了增加PO2对氧合血红蛋白饱和度的影响。

The graph you see below illustrates the effects of an increased partial pressure of oxygen on percent saturation of hemoglobin with oxygen.

下图说明了氧分压增加对血红蛋白氧饱和度的影响。
