Abstract
Background:Central venous pressure (CVP) is measured to assess intravascular fluid status. Although the clinical gold standard for evaluating CVP is invasive measurement using catheterization, the use of catheterization is limited in a clinical setting because of its invasiveness. We developed novel non-invasive technique, enclosed-zone (ezCVPTM) measurement for estimating CVP. The purpose of this study was to assess the feasibility of ezCVP and the relationship between ezCVP and CVP measured by a catheter. Methods and Results:We conducted 291 measurements in 97 patients. Linear regression analysis revealed that ezCVP was significantly correlated with CVP (r=0.65, P10 mmHg were 0.59, 0.96 and 14.8 with a cut-off value of 11.9 and 0.79, 0.97 and 26.3 with a cut-off value of 12.7. Conclusions:These findings suggest that ezCVP measurement is feasible and useful for assessing CVP.Keywords
