A new device for the continuous monitoring of oxygen uptake and carbon dioxide delivery is presented, which is based on a continuous expired gas analysis using a paramagnetic oxygen and an infrared-absorption carbon dioxide sensor. To validate the results, data of measured oxygen uptake and cardiac output calculated by the Fick principle were compared to synchronous thermodilution measurements at rest and during exercise. Measurements were performed at rest on 18 patients, additionally 13 of the patients were exercised with either 25 W or 50 W workload. The results indicate, for both measurement series, a significant correlation (r greater than 0.95, p less than 0.001) and exemplify that the measurement of oxygen uptake by expired gas analysis permits a precise analysis of the cardiovascular transport function during exercise.
介绍了一种用于连续监测氧气摄取量和二氧化碳输送量的新设备，该设备基于使用顺磁氧传感器和红外吸收二氧化碳传感器进行的连续呼出气体分析。为了验证结果，将通过菲克原理计算的测得的氧气摄取量和心输出量数据与静息和运动期间的同步热稀释测量结果进行了比较。对18名患者进行了静息测量，另外13名患者以25瓦或50瓦的工作量进行运动。结果表明，对于两个测量系列，均存在显著相关性（r大于0.95，p小于0.001），并举例说明通过呼出气体分析测量氧气摄取量可以在运动期间对心血管运输功能进行精确分析。
