Lung volume measurement can be of interest to anesthesists as well as respiratory physicians, both as a diagnostic tool and as a way to monitor the effect of respiratory therapy (for instance PEEP ventilation). Several methods exist to measure lung volume. Only two of them can be applied easily during mechanical ventilation. The wash-in wash-out of insoluble inert gas can be used in non-rebreathing (semi open) systems, or the equilibration of an inert insoluble gas which can be used in completely closed systems. In our department a completely closed anesthesia system has been developed which is particularly well suited for the equilibration method of lung volume measurement. Just like the wash-out method, the equilibration method can give information about the uniformity of ventilation-distribution within the lung.
肺容积测量对于麻醉医生和呼吸内科医生都可能是有意义的，既作为一种诊断工具，也作为监测呼吸治疗效果（例如呼气末正压通气）的一种方式。存在多种测量肺容积的方法。其中只有两种方法可以在机械通气期间轻松应用。不溶性惰性气体的冲洗法可用于无重复吸入（半开放式）系统，或者不溶性惰性气体的平衡法可用于完全密闭系统。在我们科室，已经开发出一种特别适合用于肺容积测量平衡法的完全密闭麻醉系统。与冲洗法一样，平衡法可以提供有关肺内通气分布均匀性的信息。
