Blood oxygen affinity in large white pig.
Large white pig and human blood oxygen affinities are different due to different primary structures of hemoglobin. Empirical equations are reported to predict the oxygen partial pressure at half-saturation of hemoglobin (p50) from known values for pH, pCO2 and 2,3-diphosphoglycerate, with an accuracy of +/- 0.82 torr.
