摘要
目的分析西宁地区慢性肺心病呼吸衰竭患者血气特点。方法治疗前采集常氧环境中桡动脉血1ml,以瑞士AVL-3型血气酸碱分析仪行PaCO2、PaO2、pH、SaO2和P(A-a)O2测定。结果西宁地区慢性肺心病呼吸衰竭患者PaCO2、SaO2、PaO2和P(A-a)O2均明显低于低海拔地区患者,pH值较低海拔地区患者高,二者存在显著性差异(P<0.01)。结论西宁地区慢性肺心病呼吸衰竭患者与低海拔地区患者相比有低碳酸血症者多、弥散功能强、低氧血症程度高等特点。
Objective To investigate the feature of blood - gas in the patients with chronic cor pulmonale complicated with respiratory failure at Xining area. Methods 1 ml of peripheral blood was taken before the treat- ment and the Paco2 ,Pao2, pH,Sao2 and P（A-a）o2 were detected with bloodgas and acid -alkali analyzer（Swiss made AVL -3 type）. Results The Paco2 ,Pao2 ,Sao2 and P（A-a）o2 of patients with chronic cor pulmonale complicated with respiratory failure at Xining area were significantly lower than that of in low altitude, pH of the former was higher than the later（ P 〈 0.01 ）. Conclusion The patients with chronic cor pulmonale complicated with respiratory failure at Xining area show the features of hypoxemia, hypocarbohemia and strong diffusion.
