慢性气道阻塞（CAO）患者普遍存在内源性呼气末正压（i-PEEP）[1]，适度的外加PEEP可对抗i－PEEP而减少呼吸功耗，还可使呼气中易闭陷的气道免于闭陷，改善患者通气功能，敌对CAO患者有积极的治疗作用[2]。但PEEP最适水平的确定目前主要依赖于对iPEEP的测量，而测量iPEEP的方法
Endogenous positive end-expiratory pressure (i-PEEP) is commonly present in patients with chronic airway obstruction (CAO) [1], and modest PEEP can counteract i-PEEP to reduce respiratory power consumption and to facilitate expiration Trapped airway from the trap, improve patient ventilation, the enemy of CAO patients have a positive therapeutic effect [2]. However, the determination of the PEEP optimum level currently mainly depends on the measurement of iPEEP, and the method of measuring iPEEP
