作者等对16例慢性阻塞性枝气管炎及严重肺原性心脏病心力衰竭住院患者用Venti 面罩,28%氧浓度,每天控制性吸氧治疗,共6周。试验是在病人的急性发作症状控制后,心肺处于临床稳定的状态下进行的。吸氧治疗前后各作了肺血液动力学,血液粘稠度,血球压积及常规肺功能检查,将其结果作如下比较:吸氧治疗6周后平均肺动脉压有明显下降,自42下降至30mmHg(P<0.001),心搏出量没有改变,血液粘稠度及血球压积明显降低,前者
The author of 16 patients with chronic obstructive bronchitis and severe pulmonary heart disease hospitalized with Venti mask, 28% oxygen concentration, daily controlled oxygen therapy for 6 weeks. The trial was performed in a clinically stable state of the heart and lung after control of the patient’s acute exacerbation. Before and after oxygen therapy made pulmonary hemodynamics, blood viscosity, hematocrit and routine pulmonary function tests, the results for the following comparison: 6 weeks after oxygen therapy, mean pulmonary artery pressure decreased significantly from 42 to 30mmHg (P <0.001), cardiac output did not change, blood viscosity and hematocrit decreased significantly, the former
