目的：探讨慢性阻塞性肺疾病合并左心衰竭的诊断方法，并分析使用无创呼吸治疗的临床价值。方法：总结31例患者诊断的经验，并使用无创呼吸机治疗，比较治疗前后血气分析结果，并统计呼吸机治疗前后患者临床症状改善情况。结果：治疗后患者pH恢复正常，显著高于治疗前（P＜0．05），且PO2和PCO2均恢复正常，均优于治疗前（P＜0．05），治疗后患者存在端坐呼吸、精神萎靡和呼吸困难的比率均显著低于治疗前（P＜0．05）。结论：COPD合并左心衰竭较易漏诊，使用无创正压通气治疗，提高患者血氧含量，减轻呼吸机做功，纠正低氧血症，避免有创通气的并发症及脱机困难。

Objective To investigate the diagnosis of chronic obstructive pulmonary disease complicated with left heart failure and value of noninvasive respiratory therapy. Methods Summaried the diagnosis experience of 31 cases and used the noninvasive ventilator therapy, compared the results of blood gas analysis and statistics of ventilator and the clinical symptoms improved before and after treatment. Results After treatment the PH was normal and was significantly higher than before (P<0.05), and PO2 and PCO2 were returned to normal and were better than before (P<0.05), patients with existing orthopnea, spirit were dispirited and were significantly lower than before (P<0.05). Conclusions COPD complicated with left heart failure is missed, the use of noninvasive positive pressure ventilation can improve the oxygen content, reduce ventilator work, correct hypoxemia, and it also avoids invasive ventilation complications and difficult off-line.
