Question

At normal body temperature (38 °C), hemoglobin is 72% saturated at a partial pressure of O2 of 40 mmHg. Use the oxygen–hemoglobin dissociation curves to determine the oxygen saturation of hemoglobin at a partial pressure of O2 of 40 mmHg, if the temperature drops to 20 °C. 100 10°C 80 20°C 38°C 60 43°C O2 saturation of hemoglobin (%) 40 20 0 20 40 60 80 100 PO2 (mm Hg) oxygen saturation: %
