Based on the oxygen dissociation curve, if hemoglobin in the RBCs are 91% saturated in the lungs (PO2 of 100). What is the percentage of oxygen saturation in the hemoglobin at a PO2 of 30? What percent of the oxygen was released?

Based on the oxygen dissociation curve, if hemoglobin in the RBCs are 95% saturated in the lungs (PO2 of 100). The tissue that the RBC will be passing is highly active producing more CO2 and the pH is decreased. This will shift the curve to
