Investigation of Plasma Carbonic Acid pK' of the Chicken
AN accurate calculation of carbon dioxide tension in blood plasma by means of the Henderson-Hasselbalch equation requires the use of an exact pK′ for carbonic acid. According to Severinghaus (1956a), total errors up to 15% in computing PCO 2 of blood samples are not uncommon. To the present time nea...
