摘要:
A method for monitoring autoregulation includes, using a processor, receiving a blood pressure signal, a regional oxygen saturation signal, and a blood volume signal from a patient. The method also includes determining a first linear correlation between the blood pressure signal and the regional oxygen saturation signal and determining a second linear correlation between the blood pressure signal and the blood volume signal. The method also includes determining a confidence level associated with the first linear correlation based at least in part on the second linear correlation and providing a signal indicative of the patient's autoregulation status to an output device based on the linear correlation and the confidence level.
摘要(中):
用于监测自动调节的方法包括使用处理器从患者接收血压信号,区域氧饱和度信号和血量信号。 该方法还包括确定血压信号与区域氧饱和度信号之间的第一线性相关性并确定血压信号与血容量信号之间的第二线性相关性。 该方法还包括至少部分基于第二线性相关来确定与第一线性相关性相关联的置信度水平,并且基于线性相关性和置信度水平向输出设备提供指示患者的自动调节状态的信号。 p>
