Abstract
Simultaneous peripheral and central venous pressure monitoring for evaluating cardiac preload in critically ill patients

The main purpose of fluid therapy during severe invasive situations, such as after major surgery and in patients with sepsis, is to maintain tissue perfusion by optimizing intravascular volume
We investigated the relationship between central venous pressure (CVP) and peripheral venous pressure (PVP)
The CVP and PVP value correlated with each other (r2=0.83, P
Summary
The main purpose of fluid therapy during severe invasive situations, such as after major surgery and in patients with sepsis, is to maintain tissue perfusion by optimizing intravascular volume. Several objective indicators to estimate cardiac preload have been developed and used, such as central venous pressure (CVP) and stroke volume variation (SVV). The performance of dynamic indicators including SVV is reportedly better than that of static indicators [1,2,3]. Since special catheters and expensive machines, such as the FloTrac/Vigileo Monitor® system, must be used to measure SVV, not all facilities can perform this measurement. This consideration prompted us to estimate cardiac preload by measuring and comparing two static indicators, peripheral venous pressure (PVP) and CVP
