呼吸衰竭(以下简称呼衰)是呼吸道疾病死亡的主要因素之一,国内有人统计PaO_2≤4.1kPa,死亡率达77.8％,本文旨在探讨PaO_2≤6kPa的严重呼衰,应用改善通气与降低肺血管阻力的综合治疗效果。 1 临床资料 1.1 病例选择:以呼吸道疾病为主,经血气分析PaCO_2≤6kPa有或无PaO_2≥6.7kPa共54例,男41例,女13例,年龄20～81岁,平均62±15.6岁,其中应用机械通气20例。 1.2 检测项目:血像、肝肾功能、痰致病培养、血气分析、血清K~+、Na~+、Cl~-、Ca~(++)、心电图以及胸
Respiratory failure (hereinafter referred to as respiratory failure) is one of the major causes of death from respiratory diseases. Some people in China have statistics of PaO_2≤4.1kPa with a mortality rate of 77.8%. This article aims to investigate severe respiratory failure with PaO_2≤6kPa. Comprehensive treatment of vascular resistance effect. 1 Clinical data 1.1 Case selection: mainly respiratory diseases, blood gas PaCO_2 ≤ 6kPa PaO_2 ≥ 6.7kPa with or without a total of 54 cases, 41 males and 13 females, aged 20 to 81 years, mean 62 ± 15.6 years old, Which application of mechanical ventilation in 20 cases. 1.2 Test items: blood, liver and kidney function, sputum pathogenic culture, blood gas analysis, serum K ~ +, Na ~ +, Cl ~ -, Ca ~ (++), ECG and chest
