Method and apparatus for determining cerebral desaturation in patients undergoing deep hypothermic circulatory arrest
Abstract:
A method and apparatus for determining cerebral oxygen saturation in a subject is provided. The method comprises the steps of: a) determining tissue oxygen saturation values using a NIRS type oximeter over a period of time; b) modeling a rate of change in the tissue oxygen saturation values; and c) determining an amount of time until a predetermined tissue oxygen saturation value is reached using the modeling of the tissue oxygen saturation values.
Abstract(Chinese):

提供了一种用于确定受试者中的脑氧饱和度的方法和装置。 该方法包括以下步骤：a）使用NIRS型血氧计在一段时间内确定组织氧饱和度值; b）对组织氧饱和度值的变化率进行建模; 以及c）使用所述组织氧饱和度值的建模来确定达到预定组织氧饱和度值的时间量。
