WebbIn cases of chronic hypoxia (high altitude or anemia) the body produces more 2,3-BPG and shifts the curve to the right. At a PO2 of 20 mmHg, how much more oxygen is released at an exercising muscle cell whose pH is 7.2 than at a cell with a pH of 7.4? WebbThe higher the partial pressure of oxygen (pO2) in the blood, the higher the oxygen saturation. This relationship is not linear, but s-shaped and can be represented in the oxygen dissociation curve (see Fig. 4).
