title: Studies on the relationship between the equilibrium curve of oxyhemoglobin and 2,3-diphosphoglycerate in open-heart surgery.
abstract: The relationship between decreased oxygen affinity of hemoglobin and intraerythrocyte 2,3-diphosphoglycerate (2,3 DPG) concentration was confirmed and its existence during the period of open-heart surgery was demonstrated. It is suggested that the trauma sustained by the erythrocytes during their extracorporeal circulation is responsible, in large measure, for the decrease in 2,3 DPG concentration.
