Continuous measurement and monitoring of the expiratory carbon dioxide concentration can be performed with modern measurement devices routinely without any problem today. After a short introduction to measurement techniques the comprehensive monitoring possibilities of this method are described by multiple examples. No only actual disturbances of the ventilation, the circulation and the metabolism, but also malfunction or inadequate control of the anaesthesia machine can be recognized without substantial time delay. But an actual alteration of the CO2 value necessitates careful analysis of the underlying problem which is greatly facilitated by a graphic display of the CO2 signal, the capnogram. The knowledge of possibly occurring artificial alterations of the CO2 measurement, which are demonstrated too, prevents dangerous misinterpretations. By continuous measurement of the expiratory CO2 concentration, not only can the ventilation parameters be set optimally, but multiple life threatening complications can be detected very early and corrected immediately. Thus, this monitoring technique essentially contributes to the patients safety during anaesthesia.
如今，使用现代测量设备可以常规地、毫无问题地连续测量和监测呼气二氧化碳浓度。在对测量技术进行简短介绍后，通过多个示例描述了该方法的全面监测可能性。不仅可以毫无显著时间延迟地识别通气、循环和代谢的实际紊乱，还能识别麻醉机的故障或控制不当。但是，二氧化碳值的实际变化需要对潜在问题进行仔细分析，而二氧化碳信号的图形显示即二氧化碳图极大地促进了这一分析过程。对可能出现的二氧化碳测量人为变化的了解（文中也对此进行了说明）可防止危险的错误解读。通过连续测量呼气二氧化碳浓度，不仅可以优化通气参数的设置，还能非常早期地检测到多种危及生命的并发症并立即进行纠正。因此，这种监测技术对麻醉期间的患者安全至关重要。
