摘　　要：目的:研究老年慢性阻塞性肺病(COPD)患者急性发作期肺泡气-动脉血氧分压差[P(A-a)O2]的变化规律。方法:对我科1年来收治的30例老年COPD患者的血气分析进行研究。结果:P(A-a)O2在发作期与恢复期差异有显著性。结论:P(A-a)O能敏感反映患者病情转归。Objective To study the tendency of Alveolar-arterial oxygen gradient in elderly patients who have acute exacerbations of chronic obstructive pulmonary desease. Methods We analysed blood gas analysis of thirty patients with AECOPD during last year in our unit. Results Alveolar-arterial oxygen gradient turned down when patients recovered. Conclusion Alveo- lar-arterial oxygen gradient can reflect the status of the desease sensitively.
