    • Described is an apparatus and method of optoacoustic monitoring of blood concentrations of one or more constituents by directing a flow of a patient's blood through a substantially transparent vessel to optoacoustically detect a concentration of one or more constituents. To detect constituents, pulses of laser light can be passed through the blood flow at one or more frequencies in order to generate an altered laser emission from the exposed blood, and/or induce detectable optoacoustic responses from the constituents. The detectable responses can be detected and measured by analyzing an alteration of the laser emissions and/or the frequency, slope and/or amplitude of the optoacoustic responses for different constituents in the blood.
    • 描述了通过将患者血液的流动引导通过基本上透明的血管来光声检测一种或多种成分的浓度的光声监测一种或多种成分的血液浓度的装置和方法。 为了检测成分,激光的脉冲可以以一个或多个频率通过血流,以产生来自暴露的血液的改变的激光发射,和/或诱导来自组分的可检测的光声响应。 可以通过分析激光发射的变化和/或血液中不同成分的光声响应的频率,斜率和/或振幅来检测和测量可检测的响应。
