摘　　要：目的:探讨P(A-a)O2在慢性阻塞性肺疾病(COPD)合并肺栓塞(PE)患者中的应用价值。方法:选取我院呼吸科COPD合并PE住院患者30例,同期住院患者单纯COPD患者80例,单纯PE患者40例,检测其血气水平及P(A-a)O2。结果:P(A-a)O2在单纯PE组及COPD合并PE组较单纯COPD组明显增大(P<0.05),与PE危险程度正相关。结论:在COPD患者中P(A-a)O2增大,提示患者出现氧和功能障碍,可能合并PE,应尽早相关检查,以避免漏诊误诊。Objective： To investigate the application value of P（A-a）O2 in patients with chronic obstructive pulmonary disease（COPD） complicated with pulmonary embolism（PE）. Methods： 30 patients with COPD in our hospital were selected, 80 patients with COPD, 40 patients with PE, and P（A-a）O2. Results： P（A-a）O2 was significantly increased in PE group and COPD group compared with PE group（P〈0.05）, which was positively correlated with the level of PE. Conclusion： In patients with P（A-a）O2 COPD increased, suggesting that patients with oxygen and dysfunction, may merge PE, should be as soon as possible to avoid misdiagnosis.
