At normal blood pH (7.4), hemoglobin is 40% saturated at a partial pressure of oxygen (O?) of 20 mmHg. Use the oxygen–hemoglobin dissociation curves to determine the oxygen saturation of hemoglobin at a partial pressure of O? of 20 mmHg, if the blood pH drops to 7.2.

At normal blood pH (7.4), hemoglobin is 40% saturated at a partial pressure of oxygen (O₂) of 20 mmHg. Use the oxygen–hemoglobin dissociation curves to determine the oxygen saturation of hemoglobin at a partial pressure of O₂ of 20 mmHg, if the blood pH drops to 7.2. oxygen saturation:

Calculate the fractional saturation of hemoglobin at pO2 = 30 torr (the oxygen pressure of venous blood) and n=2.8. Assuming the p50 value for hemoglobin with oxygen is 26 torr.
