呼吸衰竭(简称呼衰)常引起血和脑脊液(CSF)酸碱平衡紊乱,二者变化既可相同也可相反。因此,认识CSF的酸碱代谢基础、变化规律及与血液酸碱平衡的关系,对于及早防治呼衰时的CSF酸碱平衡紊乱,终止脑的不可逆性损害,提高呼衰的抢救成功率,具有重大意义。【CSF酸碱平衡的调节】正常人的脑脊液酸碱状态:CSF pH7.312±0.016:CSF HCO_3~-22mEg/L±1.5;P_(CSP)CO_2 46.7mmHg±3.5。CSF的缓冲能力
Respiratory failure (referred to as respiratory failure) often cause blood and cerebrospinal fluid (CSF) acid-base balance disorders, the two changes can be the same or vice versa. Therefore, the understanding of the basis of acid-base metabolism of CSF, the relationship between changes and the relationship between blood acid-base balance for the early prevention and treatment of respiratory failure during the acid-base balance disorders, termination of brain irreversible damage and improve the success rate of rescue resuscitation, with Great significance. [CSF acid-base balance of normal human cerebrospinal fluid acid-base status: CSF pH7.312 ± 0.016: CSF HCO_3 ~ -22mEg / L ± 1.5; P_ (CSP) CO_2 46.7mmHg ± 3.5. CSF buffer capacity
