The need to incorporate alarms in monitoring systems is related to the growing complexity of monitoring and the large number of variables. For sophisticated alarms, information about the inputs to the patient is of importance; for example, clinical interventions such as drug administration and ventilation readjustment need to be known to the monitoring system. Alarms are triggered by signals or signal features that exceed thresholds. Each threshold must be seen as a level that needs to be set, either manually or automatically. The large number of levels to be set creates an extra workload for the clinician. Approaches to determine such levels automatically are discussed in this article. Most promising seems the multiple signal approach using an expert system. It seems reasonable to expect that information concerning alarm limits, needed for the operation of knowledge-based alarm systems, may come from integrated departmental data bases.
在监测系统中加入警报与监测日益复杂以及大量变量有关。对于复杂的警报而言，患者输入信息很重要；例如，监测系统需要了解诸如药物给药和通气调整等临床干预措施。警报由超过阈值的信号或信号特征触发。每个阈值都必须视为需要手动或自动设置的一个水平。大量需要设置的水平给临床医生带来了额外的工作量。本文讨论了自动确定此类水平的方法。最有前景的似乎是使用专家系统的多信号方法。基于知识的警报系统运行所需的有关警报限值的信息可能来自综合部门数据库，这似乎是合理的预期。
