Abstract: A universal/upgrading pulse oximeter (UPO) (210) comprises a portable unit (610) and a docking station (660,910) together providing three-instruments-in-one functionality for measuring oxygen saturation and related physiological parameters. The portable unit functions as a handheld pulse oximeter. The combination of the docked portable and the docking station functions as a stand-alone, high-performance pulse oximeter. The portable- docking station combination is also connectable to, and universally compatible with, pulse oximeters from various manufacturers through use of a waveform generator (320, 930). The UPO provides a universal sensor to pulse oximeter interface and a pulse oximeter measurement capability that upgrades the performance of conventional instruments by increasing low perfusion performance and motion artefact immunity, for example. Universal compatibility combined with portability allows the UPO to be transported along with patients transferred between an ambulance and a hospital ER, or between various hospital sites, providing continuous patient monitoring in addition to plug-compatibility and functional upgradin g for multiparameter patient monitoring systems. The image on the portable display (264, 740) is rotatable, either manually when undocked or as a function of orientation (950). In one embodiment, the docking station (660) has a web server and a network interface (1410) that allows UPO data to be downloaded and viewed as web pages over a local area network (1420) or the Internet.

Abstract: An intelligent, rule-based processor (300) provides signal quality based limits to the signal strength operating region of a pulse oximeter. These limits are superimposed on the typical gain dependent signal strength limits (314). If a sensor signal appears physiologically generated, the pulse oximeter is allowed to operate with minimal signal strength, maximizing low perfusion performance. If a sensor signal is potentially due to a signal induced by a dislodged sensor, signal strength requirements are raised. Thus, signal quality limitations enhance probe off detection without significantly impacting low perfusion performance. One signal quality measure used is pulse rate density (354), which defines the percentage of time physiologically acceptable pulses are occurring. If the detected signal contains a significant portion of unacceptable pulses, the minimum required signal strength is raised proportionately. Another signal quality measure used in conjunction with pulse rate density is energy ratio (352), computed as the percentage of total energy contained in the pulse rate fundamental and associated harmonics.

Abstract translation: 智能的基于规则的处理器（300）为脉冲血氧计的信号强度操作区域提供基于信号质量的限制。 这些极限叠加在典型的增益相关信号强度极限（314）上。 如果传感器信号出现生理生成，则允许脉搏血氧计以最小的信号强度进行操作，从而最大化低灌注性能。 如果传感器信号潜在地由于由移动的传感器引起的信号，则会提高信号强度要求。 因此，信号质量限制增强了探针检测，而不会显着影响低灌注性能。 使用的一种信号质量测量是脉率密度（354），其定义了生理上可接受的脉冲发生的时间百分比。 如果检测到的信号包含不可接受的脉冲的大部分，则所需的最小信号强度成比例地提高。 与脉率密度结合使用的另一个信号质量测量是能量比（352），其计算为脉冲速率基波和相关谐波中包含的总能量的百分比。

Abstract: A pulse oximeter (210) has an integrated mode in which it operates as a plug-in module for a multiparameter patient monitoring system (MPMS) (250). The pulse oximeter (210) also has a portable mode in which operates separately from the MPMS (250) as a battery-powered handheld or standalone instrument. The pulse oximeter (210) 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 (340), and stored in memory for trend capability. A keypad (510) provides a user interface for operational control in the portable mode.; In the integrated mode, the pulse oximeter provides oxygen saturation and pulse rate measurements to the MPMS (250) through a communications interface, along with previously stored trend data, and displayed on the MPMS monitor. The MPMS (250) also provides external power and operational control of the pulse oximeter (210) in the integrated mode. Alternatively, a docking station (660) operates as a plug-in module that provides the mechanical and electrical interface between a portable pulse oximeter (610) and MPMS instruments from a variety of manufacturers. In the integrated mode, the portable pulse oximeter (610) docks to the docking station (660), which in turn is inserted in one or more MPMS slots (290). The docking station (660) can function as a simple electrical pass-through device between the docked portable pulse oximeter (610) and the MPMS (250) or it can provide a MPMS communications interface.
