血乳酸浓度反应全身组织灌注情况，是细胞缺氧的敏感标志物，在组织灌注不良及低氧等情况下血乳酸明显增高。当灌注不良得到有效控制，低氧状态迅速纠正后，体内乳酸水平迅速降低。呼吸衰竭患者体内病理生理变化的一个主要方面就是组织细胞的氧供不足，导致血乳酸升高，甚至血乳酸中毒，本文旨在综述检测血乳酸浓度对引起呼吸衰竭常见疾病的临床指导意义，为临床上对此类疾病治疗方案的合理选择提供参考。

Blood lactate concentration reacted to body tissue perfusion is a sensitive marker for cells under hypoxia.It increased significantly when the body is in a poor perfusion and low oxygen.When hypoperfusion has been controled ef-fectively,and hypoxia quickly has been corrected,the level of lactic acid in vivo decreased rapidly.The lack of oxygen is a major aspect of respiratory failure pathophysiological changes,which causing the blood lactic acid increased,further-more blood lactic acidosis.The purpose of this review is to detect blood lactic acid and to analyse of the test results.In the end,we summarized clinical significance of blood lactic acid in the common disease of respiratory failure and pro-vided rational clinical therapy for such diseases.
