متن کاملThe acidosis-induced right shift of the HbO2 dissociation curve is maintained during erythrocyte storage
BACKGROUND AND OBJECTIVES In fresh blood, tissue hypoxia increases microcirculatory acidosis, which enhances erythrocyte O(2) unloading and increases the amount of available O(2). Storage of erythrocytes increases the HbO(2) affinity and reduces O(2) unloading. We examined the development of the affinity change during a period of 5 weeks of storage by present blood bank standards, and investiga...
