    • The invention concerns a method for controlling an alarm in a medical instrument or system, the medical instrument or system detecting at least one physiological parameter of the patient. The present value of the physiological parameter is consecutively detected and an alarm delay is determined as a function of at least one detected value of the physiological parameter wherein the function yields a shorter alarm delay for increasing values of the deviation from a normal value and a longer alarm delay for decreasing values of the deviation from the normal value. Further, the duration the value of the physiological parameter exceeds or under-runs at least one predefined threshold for the physiological parameter defining an upper or lower limit for a normal range of the physiological parameter, respectively, is measured and the alarm is generated when the duration the determined value of the physiological parameter exceeds or under-runs the predefined threshold exceeds the alarm delay. This method allows for the avoidance of nuisance alarms while still indicating severe conditions of the monitored patient reliably.
    • 本发明涉及一种用于控制医疗仪器或系统中的警报的方法,所述医疗仪器或系统检测患者的至少一个生理参数。 生理参数的当前值被连续检测,并且根据生理参数的至少一个检测值确定报警延迟,其中该功能产生较短的报警延迟,用于增加偏离正常值的偏差值和较长的 报警延迟,减少偏离正常值的值。 此外,测量生理参数的值的持续时间分别超过或低于生理参数的至少一个预定义阈值,该生理参数分别限定生理参数的正常范围的上限或下限,并且当 生理参数的确定值的持续时间超过或不足预定阈值超过报警延迟。 该方法允许避免妨扰警报,同时仍然可靠地指示被监视患者的严重状况。
