    摘要： A pulse oximeter has an integrated mode in which it operates as a plug-in module for a multiparameter patient monitoring system (MPMS). The pulse oximeter also has a portable mode in which operates separately from the MPMS as a battery-powered handheld or standalone instrument. The pulse oximeter has a sensor port that receives a photo-plethysmographic signal as input to an internal processor. The pulse oximeter processes this sensor signal to derive oxygen saturation and pulse rate measurements. In the portable mode, this information is provided on its display, and stored in memory for trend capability. In the integrated mode, the pulse oximeter provides oxygen saturation and pulse rate measurements to the MPMS through a docking station to be displayed on a MPMS monitor. In the integrated mode, the portable pulse oximeter docks to the docking station, which in turn is inserted in one or more MPMS slots. The docking station can function as a simple electrical pass-through device between the docked portable pulse oximeter and the MPMS or it can provide a MPMS communications interface.

    摘要： An intelligent, rule-based processor provides a pulse indicator designating the occurrence of each pulse in a pulse oximeter-derived photo-plethysmograph waveform. When there is relatively no distortion corrupting the plethysmograph signal, the processor analyzes the shape of the pulses in the waveform to determine where in the waveform to generate the pulse indication. When distortion is present, looser waveform criteria are used to determine if pulses are present. If pulses are present, the pulse indication is based upon an averaged pulse rate. If no pulses are present, no indication occurs. The pulse indicator provides a trigger and amplitude output. The trigger output is used to initiate an audible tone “beep” or a visual pulse indication on a display, such as a vertical spike on a horizontal trace or a corresponding indication on a bar display. The amplitude output is used to indicate data integrity and corresponding confidence in the computed values of saturation and pulse rate. The amplitude output can vary a characteristic of the pulse indicator, such as beep volume or frequency or the height of the visual display spike. The visual pulse indicator is supplemented by a signal quality alert. Combined with several indicators of signal quality, the alert is used to initiate a warning when data confidence is very low. The alert may be in the form of a message generated on the pulse oximeter display to warn that the accuracy of saturation and pulse rate measurements may be compromised. A confidence-based alarm utilizes signal quality measures to reduce the probability of false alarms when data confidence is low and to reduce the probability of missed events when data confidence is high.

    摘要翻译： 智能的基于规则的处理器提供脉冲指示器，指示脉冲血氧计衍生的光体积描记器波形中每个脉冲的发生。 当相对没有变形破坏体积描记器信号时，处理器分析波形中的脉冲的形状，以确定波形中的哪一个以产生脉搏指示。 当存在失真时，使用较宽的波形准则来确定是否存在脉冲。 如果存在脉冲，则脉冲指示基于平均脉冲速率。 如果不存在脉冲，则不会发生指示。 脉冲指示器提供触发和幅度输出。 触发输出用于在显示器上启动听觉音“哔”或视觉脉搏指示，例如水平轨迹上的垂直尖峰或条形显示屏上的相应指示。 振幅输出用于指示计算的饱和度和脉率值的数据完整性和相应的置信度。 振幅输出可以改变脉冲指示器的特性，例如哔音体积或频率或视觉显示尖峰的高度。视觉脉冲指示器由信号质量警报补充。 结合信号质量的几个指标，当数据置信度非常低时，警报用于发起警告。 警报可以是在脉搏血氧计显示器上产生的消息的形式，以警告饱和度和脉搏率测量的精度可能受到损害。 基于置信度的报警器利用信号质量测量来降低数据置信​​度较低时的假警报概率，并且在数据置信度高时降低错过事件的可能性。
