Abstract

The peripheral venous system serves as a volume reservoir due to its high compliance and can yield information on intravascular volume status. Peripheral venous waveforms can be captured by direct transduction through a peripheral catheter, non-invasive piezoelectric transduction, or gleaned from other waveforms such as the plethysmograph. Older analysis techniques relied upon pressure waveforms such as peripheral venous pressure and central venous pressure as a means of evaluating fluid responsiveness. Newer peripheral venous waveform analysis techniques exist in both the time and frequency domains, and have been applied to various clinical scenarios including hypovolemia (i.e. hemorrhage, dehydration) and volume overload.

外周静脉波形的生理学和临床应用。
外周静脉系统由于其高顺应性而充当容量储存库,可以提供血管内容量状态的信息。外周静脉波形可以通过外周导管直接转导、无创压电转导或从其他波形(如容积描记器)收集来捕获。旧的分析技术依赖于压力波形,如外周静脉压和中心静脉压作为评估液体反应的手段。较新的外周静脉波形分析技术存在于时域和频域,并已应用于各种临床情况,包括低血容量(即出血、脱水)和容量过载。
