摘　　要：目的　探讨昆明地区慢性肺心病酸碱紊乱特点及呼吸衰竭血气诊断依据。方法　对32 0例 4 5 0例次慢性肺心病患者按海平面标准和昆明地区正常血气参考值提出的诊断依据进行对比分析。结果　昆明地区慢性肺心病酸碱紊乱类型以单纯呼吸性酸中毒、呼吸性酸中毒并代谢性碱中毒、呼吸性酸中毒并代谢性酸中毒为主 ,对呼吸衰竭的血气诊断标准建议为PaO2 <5 0mmHg或 /和PaCO2 >4 1mmHg。结论　建立不同海拔高度地区酸碱紊乱及呼吸衰竭诊断标准有助于对疾病的正确判断。Objective To asses the characteristics of acid-basic disturbances and their implication in diagnosis of respiratory failure in patients with chronic pulmonary heart disease in Kunming region.Methods The gas blood analysis results of 320 patients with chronic Cor pulmonale were compared with two different standards, ie.sea-level standard and Kunming's normal standards.Results In Kuming region common types of acid-basic disturbances in Cor pulmoale were respiratory acidosis, respiratory acidosis with metabolic alkalosis,and respiratory and metabolic acidosis.A diagnostic standards of PaO_2<50 mm Hg or/with PaCO_2>41 mm Hg was recommended.Conclusion Different standards for diagnosis acid-basic disturbances and respiratory failure based on different altitude would be valuable.
