Effect of Lateral Positioning on Central Venous Pressure
… the effects of lateral positioning on central venous pressure. It was hypothesized that lateral positioning would not significantly change the central venous pressure so long as the subjects were placed on the same horizontal plane for both supine and lateral measurements. It was also …

Central Venous Pressure Reference Points Measured on Post-Mortem Subject
<p>Hemodynamically the central venous pressure should be the same in both the supine and lateral positions. The accurate determination of an external zero reference level corresponding with mid right atrial level would make possible reliable measurements in either position. The purpose of this …

A Study of Variability in Locating the External Reference Point for Central Venous Pressure Determination
… two methods, the external reference point for central venous pressure (CVP) determinations. In the literature on CVP and on CVP value discrepancies, no reports were found of studies related to variability among medical personnel in locating the point.</p> <p>The nurse participants in this study …

V for Venous Pressure
… accurate and noninvasive methods to measure central venous pressure and central arterial pressure. Force-coupled ultrasound imaging of blood vessels is a process which outputs ultrasound images containing at least one segmented blood vessel of interest and assigns a force to each image. Data …

Exploration, processing and visualization of physiological signals from the ICU
… explored include heart rate, arterial blood pressure, pulmonary artery pressure, and central venous pressure measurements. Following an introduction to these signals, several methods are proposed for visualizing the data using time and frequency domain techniques. By way of a patient case …

A Method for Determining the Location of the Central Venous Reference Point in Subjects with Hyperinflation Lung Disease
… for measuring the zero reference point of central venous pressure in subjects with hyperinflation lung disease.</p> <p>The primary purpose of this study was to find a method to determine if the external reference point that is currently being used on patients with hyperinflation lung …

Controlled cross circulation: effects on donor hemodynamics
… ventricular dP/dt max, pulmonary capillary wedge pressure, blood volume, systemic vascular resistance, heart rate, total protein, platelet count, and white blood cell count did not change significantly. Donor cardiac output, end diastolic volume, central venous pressure, stroke volume, mean …

A Combined In Vivo and In Vitro Approach to the Study of Endotoxemia in Swine
… sustained increases in mean pulmonary artery pressure, pulmonary vascular resistance, pulmonary arterial wedge pressure, heart rate, hematocrit, and the arterial partial pressure of carbon dioxide. Transient increases were also observed in central venous pressure and airway pressure. Transient …

An eICU/ICU Collaborative to Reduce Sepsis Mortality
… Nurses and physicians need to recognize that central venous pressure (CVP) is no longer a recommended or accepted measure of hemodynamic stability. The latest evidence-based practice supports NICOM in conjunction with passive leg raise (PLR) as a foundational guideline for fluid resuscitation. …

Pulmonary Artery and Central Venous Pressures as Prognostic Indicators of Post Lung Transplant Outcome
… between elevated mean pulmonary arterial pressure (mPAP) and central venous pressure (CVP) on poor prognosis in patients undergoing lung transplants has been widely debated. We hypothesized that not only the isolated values of mPAP and CVP, but also the combination of discordant values in …

Exercise Induced Hypervolemia: Role of Exercise Mode
… volume expansion. Differences in hydrostatic pressure gradients between the standing and seated position indicate that treadmill exercise might promote a greater plasma volume expansion than cycle ergometer exercise. To test this hypothesis ten subjects performed intermittent high intensity …

Cardiopulmonary Predicators of Dysfunctional Ventilator Weaning Response after Coronary Artery Bypass Graft
… which included heart rate (HR), mean arterial pressure (MAP), central venous pressure (CVP), cardiac output (CO), respiratory rate (RR), mixed venous oxygen saturation (SVO<sub>2)</sub>, oxygen saturation (SPO<sub>2)</sub>, pulmonary artery diastolic pressure (PAD) and pulmonary artery systolic …
