As is often the case in medicine, the risk to benefit ratio of blood transfusion requires careful examination. The decision to transfuse a patient cannot be based only on the haemoglobin or the haematocrit concentration. In a given clinical situation, tolerance to anaemia will depend on the ability of the patient to recruit his compensatory mechanisms in accordance with his metabolic demand. Maintenance of circulating volume is of paramount importance. In the absence of a universal transfusion trigger, decision to transfuse a patient with an haemoglobin concentration between 7.0 and 10.0 g dL-1 depends primarily on clinical judgement. With the exception of emergency situations, blood transfusion will be realized on a unit-by-unit basis, and the efficacy of treatment should be evaluated after each transfused unit.
在医学领域，输血的风险效益比通常需要仔细考量。给患者输血的决定不能仅基于血红蛋白或血细胞比容浓度。在特定的临床情况下，对贫血的耐受性将取决于患者根据其代谢需求调动代偿机制的能力。维持循环血量至关重要。由于缺乏通用的输血触发指标，对于血红蛋白浓度在7.0至10.0 g/dL-1之间的患者，输血决定主要取决于临床判断。除紧急情况外，输血将逐单位进行，且每次输注一个单位后都应评估治疗效果。
