Remote monitoring of pulmonary artery pressure has reduced heart failure (HF) hospitalizations in chronic HF as elevation of pulmonary artery pressure provides information that can guide treatment. The venous system is characterized by high capacitance, thus substantial increases in intravascular volume can occur before filling pressures increase. The inferior vena cava (IVC) is a highly compliant venous conduit and thus a candidate for early detection of change in intravascular volume. We aimed to compare IVC cross-sectional area using a novel sensor with cardiac filling pressures during experimental manipulation of volume status, vascular tone, and cardiac function.

在血管内容量和张力的实验操作过程中，下腔静脉面积的变化比充盈压力的变化更敏感

肺动脉压的远程监测减少了慢性 HF 的心力衰竭 (HF) 住院率，因为肺动脉压升高提供了可以指导治疗的信息。静脉系统的特点是电容高，因此在充盈压力增加之前，血管内容量可能会显着增加。下腔静脉 (IVC) 是一种高度顺应性的静脉导管，因此是早期检测血管内容量变化的候选者。我们的目的是在容量状态、血管张力和心脏功能的实验操作过程中，比较使用新型传感器的 IVC 横截面积与心脏充盈压。
