BACKGROUND The central venous pressure (CVP) is essential for assessing the cardiac preload and circulating blood volume in clinic. The invasive CVP measurement by central venous catheter has been reported with various complications. The aim of this study was to develop a new noninvasive method for quantification of CVP by ultrasound. METHODS AND RESULTS Seventy-six patients who had their CVP...

Orthostatic stress leads to a reduction in central venous pressure (CVP), which is an index of cardiac preload. Skin surface cooling has been shown to improve orthostatic tolerance, although the mechanism resulting in this outcome is unclear. One possible mechanism may be that skin surface cooling attenuates the drop in CVP during an orthostatic challenge, thereby preserving cardiac filling. To...

PURPOSE OF REVIEW Central venous pressure (CVP) alone has so far not found a place in outcome prediction or prediction of fluid responsiveness. Improved understanding of the interaction between mean systemic pressure (Pms) and CVP has major implications for evaluating volume responsiveness, heart performance and potentially patient outcomes. RECENT FINDINGS The literature review substantiates...

OBJECTIVES We sought to investigate the relationship between increased central venous pressure (CVP), renal function, and mortality in a broad spectrum of cardiovascular patients. BACKGROUND The pathophysiology of impaired renal function in cardiovascular disease is multifactorial. The relative importance of increased CVP has not been addressed previously. METHODS A total of 2,557 patients ...

BACKGROUND Evidences suggest that nuts consumption can improve energy metabolism. PURPOSE This study aimed to compare the effects of acute ingestion of high-oleic and conventional peanuts on appetite, food intake, and energy metabolism in overweight and obese men. METHODS Seventy one subjects (29.8 ± 2.4 kg/m2) were assigned to the groups: control (CT, n = 24); conventional peanuts (CVP, n ...

The purpose of this study was to compare hemodynamic and blood analyte responses to reduced central venous pressure (CVP) and pulse pressure (PP) elicited during graded lower body negative pressure (LBNP) to those observed during graded blood loss (BL) in conscious humans. We hypothesized that the stimulus-response relationships of CVP and PP to hemodynamic responses during LBNP would mimic tho...

BACKGROUND Despite constant fluctuations in cardiac preload caused by the effects of respiration and changes in posture on venous return to the heart, arterial blood pressure remains remarkably constant. The effects of instantaneous lung volume (ILV) and variations of central venous pressure (CVP) on blood pressure (BP) were studied by use of frequency domain techniques to quantify the contribu...

INTRODUCTION The aim of this study was to assess how mean systemic pressure (Psm) and resistance to venous return (Rvr) behave during passive leg raising (PLR) in cases of fluid responsiveness and fluid unresponsiveness. METHOD In 30 patients with an acute circulatory failure, in order to estimate the venous return curve, we constructed the regression line between pairs of cardiac index (CI) ...

The addition of rituximab to cyclophosphamide, vincristine and prednisolone (CVP) for advanced follicular lymphoma increases median time to progression by 17 months. A US societal cost-effectiveness of R-CVP versus CVP is estimated for a representative 50-year-old patient. Progression-free survival (PFS) and overall survival are based on a randomized Phase III trial. Costs are estimated using M...

OBJECTIVE To determine the correlation between central venous pressure (CVP) measured by conventional central venous access and ultrasonographic measurement of internal jugular vein (IJV) height and inferior vena cava (IVC) diameter. METHODS A prospective, cross-sectional, convenience sampling observational study. RESULTS 25 patients from the Emergency Department (ED) Universiti Kebangsaan ...
