Energy efficient system and method for physiological monitoring

A physiological monitoring system and method for the determination of at least one physiological parameter using a first low energy physiological sensor to produce a first physiological sensor signaland a high energy physiological sensor to produce a second physiological sensor signal. A motion sensor produces a motion reference signal that a mode selector switch uses to select either the first low energy physiological sensor or the second high energy physiological sensor. Alternatively, a motion related embedded component in the second physiological sensor signal is used by the mode selectorswitch to select in the first low energy sensor or the second high energy sensor. 种生理监测系统和方法，使用第低能量生理传感器产生第生理传感器信号且使用高能量生理传感器产生第二生理传感器信号来确定至少个生理参数。运动传感器产生运动参考信号，模式选择器开关使用所述运动参考信号来选择所述第低能量生理传感器或所述第二高能量生理传感器。替代地，模式选择器开关使用嵌入在第二生理传感器信号中的运动相关分量来选择所述第低能量传感器或所述第二高能量传感器。
