    • Disclosed is a system and method for providing information to the user of a medical monitoring or diagnostic device to aid in the clinical decision making process. The preferred embodiment uses two estimators or predictors of the same physiological quantity, with each of the estimators being designed to detect specific states or artifacts in the estimated parameter and thus operating at a different point on its respective ROC curve; one chosen to provide high sensitivity, the other chosen to provide high specificity. The divergence between the estimators is indicated by the use of a shaded region between their respective time trends. The use of 2 estimators of the same parameters with different performance characteristics allows the system and method of the present invention to derive additional information about the underlying physiologic process over and above that which would be available from a single estimator. The system and method of the present invention can derive information from not only the instantaneous values of the estimators and the difference between them, but also from the time trend of the difference.
    • 公开了一种用于向医疗监视或诊断装置的用户提供信息以辅助临床决策过程的系统和方法。 优选实施例使用相同生理量的两个估计器或预测器,其中每个估计器被设计为检测估计参数中的特定状态或伪影,并因此在其相应的ROC曲线上的不同点处操作; 一个选择提供高灵敏度,另一个选择提供高度的特异性。 估计量之间的差异通过使用各自时间趋势之间的阴影区域来表示。 使用具有不同性能特征的相同参数的2个估计器允许本发明的系统和方法获得关于基本生理过程的附加信息,超过可从单个估计器获得的生理过程。 本发明的系统和方法不仅可以从估计器的瞬时值和它们之间的差异中导出信息,而且可以从差异的时间趋势中获得信息。
