摘要：
Central Venous Pressure (CVP) is non-invasively determined with accuracy comparable to invasive measurement techniques. To do so, curves are plotted based on non-invasively determined patient information obtained by applying a controllable variable (pressure) to a vein of interest at a non-distal point and taking certain measurements (such as pressure and volume measurements) from the patient. An example of a controllable variable is voltage applied in incremental inflation/deflation of a vascular cuff (1). A curve is plotted based on datapoints (such as a volume increase curve or a volume decline curve). Pertinent, accurate CVP and/or blood volume information is obtained from the slope of the non-invasive-based curve. Accurate CVP information is provided without the risks and disadvantages of invasive measurements.
摘要（中）：
中心静脉压（CVP）是非侵入式确定的，与入侵测量技术相当。 为此，基于非侵入式确定的患者信息绘制曲线，所述患者信息是通过在非远端点对感兴趣的静脉施加可控变量（压力）并从患者进行某些测量（例如压力和体积测量） 。 可控变量的一个例子是在血管袖带的增量充气/放气中施加的电压（1）。 基于数据点（如体积增加曲线或体积下降曲线）绘制曲线。 从非侵入性曲线的斜率获得相关的准确CVP和/或血容量信息。 提供准确的CVP信息，无侵入性测量的风险和缺点。
