Association between elevated central venous pressure and outcomes in critically ill patients

open access: yesAnnals of Intensive Care, 2017
Background Some prior studies have shown that elevated mean central venous pressure in certain patient populations and disease processes may lead to poor prognosis.

Venous return and mean systemic filling pressure: physiology and clinical applications

open access: yesCritical Care, 2022
Venous return is the flow of blood from the systemic venous network towards the right heart. At steady state, venous return equals cardiac output, as the venous and arterial systems operate in series.

Monro-Kellie 2.0: The dynamic vascular and venous pathophysiological components of intracranial pressure [PDF]

open access: yesJournal of Cerebral Blood Flow and Metabolism, 2016
For 200 years, the ‘closed box’ analogy of intracranial pressure (ICP) has underpinned neurosurgery and neuro-critical care. Cushing conceptualised the Monro-Kellie doctrine stating that a change in blood, brain or CSF volume resulted in reciprocal ...

Hepatic Venous Pressure Gradient

open access: yesClinical Liver Disease, 2021

The influence of spinal venous blood pressure on cerebrospinal fluid pressure

open access: yesScientific Reports, 2023
In Alligator mississippiensis the spinal dura is surrounded by a venous sinus; pressure waves can propagate in the spinal venous blood, and these spinal venous pressures can be transmitted to the spinal cerebrospinal fluid (CSF).

Changes in mean systemic filling pressure as an estimate of hemodynamic response to anesthesia induction using propofol

open access: yesBMC Anesthesiology, 2022
Background Even a small change in the pressure gradient between the venous system and the right atrium can have significant hemodynamic effects. Mean systemic filling pressure (MSFP) is the driving force of the venous system.

Head Elevation, Cerebral Venous System, and Intracranial Pressure: Review and Hypothesis

open access: yesStroke: Vascular and Interventional Neurology, 2023
Background Facilitation of venous outflow from the brain is largely believed to be responsible for the beneficial effect of head elevation on intracranial pressure (ICP). However, the impact on cerebral perfusion pressure can be deleterious. Although the

The venous contribution to cardiovascular performance: From systemic veins to left ventricular function: A review [PDF]

open access: yesScripta Medica, 2021
The venous system contains ≈ 70 % of the total blood volume and is responsible in heart failure for key symptoms of congestion. It is active: it can increase or relax its tone with physiologic or pharmacologic stimuli.

Ambulatory venous pressure revisited [PDF]

open access: yesJournal of Vascular Surgery, 2000
The purpose of this study was to describe a method for measuring the deep venous pressure changes in the lower extremity and compare it with those obtained in the dorsal foot vein.After cannulation of the posterior tibial vein, a catheter with a pressure transducer in its tip was inserted and placed at the knee joint level.
