呼吸衰竭(以下简称呼衰)的药物治疗主要是针对呼衰引起各系统的临床症状和并发症的治疗。本文对具体有关问题,结合临床体验,总结讨论于下。一、呼吸中枢兴奋药的应用:P_aO_2降低或/和 P_aCO_2升高对呼吸均有较强的兴奋作用,因此若无影响呼吸中枢和动脉化学感受器的疾病,一般在早中期呼衰,呼吸频率和节律尚未见异常时,无需应用呼吸中枢兴奋药。当重度呼衰,呼吸中枢对 GO_2的敏感性降低,出现呼吸中 Respiratory failure (hereinafter referred to as respiratory failure) drug therapy is mainly for respiratory failure caused by the system of clinical symptoms and complications of treatment. This article on the specific issues, combined with clinical experience, summed up the discussion below. First, the respiratory center stimulant application: P_aO_2 decreased or / and increased P_aCO_2 have strong respiratory effects, so if there is no respiratory and arterial chemoreceptors disease, usually in early and middle respiratory failure, respiratory rate and Rhythm has not seen abnormalities, no need to use respiratory stimulants. When severe respiratory failure, respiratory center on GO_2 decreased sensitivity, appear in the breath
