目的：探讨双水平气道正压通气（ＢＩＰＡＰ）对ＣＯＰＤ稳定期患者的长期疗效。方法：回顾性对照研究。对在本所接受ＢＩＰＡＰ治疗的２６例稳定期ＣＯＰＤ病人进行２年的随访，并与同期的２４例病人对照。结果：与对照组相比，接受了ＢＩＰＡＰ治疗后的稳定期ＣＯＰＤ病人在较长时间内（２年）气促仍能得到缓解，住院和急诊就诊次数减少。但两组病人的病死率无显著性差别。结论：ＢＩＰＡＰ无创通气是稳定期ＣＯＰＤ病人有效的康复治疗手段
Objective: To investigate the long-term effect of bipolar positive airway pressure (BIPAP) on stable COPD patients. Methods: A retrospective, controlled study. Twenty-six patients with stable COPD treated with BIPAP in our hospital were followed up for 2 years and compared with 24 patients in the same period. Results: Compared with the control group, patients with stable COPD after BIPAP treatment were still relieved for a long period of time (2 years), and hospitalizations and emergency visits decreased. However, there was no significant difference in the case fatality rates between the two groups. Conclusion: BIPAP noninvasive ventilation is an effective rehabilitation treatment for stable COPD patients
