    • Reducing noise in a signal is provided. A first filter includes a selectively definable passband for filtering a first signal used in determining at least one patient parameter. A characteristic analyzer detects a characteristic of a second signal and generates a variability measurement value using a series of data values within the second signal over a previously occurring window of time. A filter controller coupled to the characteristic analyzer uses the variability measurement value to define a characteristic of the passband for the first filter and selectively tunes the passband of the first filter according to the defined characteristic. Related apparatus, systems, techniques, and articles are also described.
    • 减少信号中的噪音。 第一滤波器包括用于对用于确定至少一个患者参数的第一信号进行滤波的可选择性定义的通带。 特性分析器检测第二信号的特性,并使用第二信号内的先前发生的时间窗口内的一系列数据值产生可变性测量值。 耦合到特性分析器的滤波器控制器使用变化性测量值来定义第一滤波器的通带的特性,并根据定义的特性选择性地调谐第一滤波器的通带。 还描述了相关的装置,系统,技术和文章。

    • An apparatus and method for measuring at least two patient parameters is provided. A first cuff includes a first inflatable bladder, a first light emitting device and a first sensor that senses light data for use in calculating at least two patient parameters. A second cuff includes a second inflatable bladder, a second light emitting device and a second sensor that senses light data for use in calculating the at least two patient parameters. A controller is coupled the first and second sensors and when the controller causes the bladder of one of the first and second cuffs to inflate, the sensor of the one of the first and second cuffs sensing first light data used in determining a first of the at least two patient parameters and the sensor of the other of the one of first and second cuffs simultaneously senses second light data used in determining of a second of the at least two patient parameters.
