Venous volume and compliance in the calf and forearm does not change after acute endurance exercise performed at continuous or interval workloads

open access: yesPhysiological Reports, 2022
Short‐term endurance exercise training for 6–8 weeks leads to increases in venous volume and compliance in the limbs. However, it is not known whether these venous vascular properties are improved by acute endurance exercise.

The effects of repetitive electric cardiac stimulation in dogs with normal hearts, complete heart block and experimental cardiac arrest [PDF]

open access: yes, 1955
Direct cardiac stimulation was conducted in the open chest. In normal animals, auricular stimulation at frequencies faster than the spontaneous rate caused little change in vascular pressures or cardiac output.

Changes in Hepatic Venous Pressure Gradient Predict Hepatic Decompensation in Patients Who Achieved Sustained Virologic Response to Interferon‐Free Therapy

open access: yesHepatology, 2019
Sustained virologic response (SVR) to interferon (IFN)‐free therapies ameliorates portal hypertension (PH); however, it remains unclear whether a decrease in hepatic venous pressure gradient (HVPG) after cure of hepatitis C translates into a clinical ...

Venous pressure during intravenous regional anesthesia: Implications for setting tourniquet pressure

open access: yesJournal of Anaesthesiology Clinical Pharmacology, 2018
Background and Aims: Intravenous regional anesthesia (IVRA) is utilized for upper extremity surgery, but higher tourniquet pressure and longer inflation time increase the risk of soft tissue and nerve injury. We investigated the duration and magnitude of

Absence of reflex vascular responses from the intrapulmonary circulation in anaesthetised dogs [PDF]

open access: yes, 2000
The aim of this investigation was to determine whether reflex cardiovascular responses were obtained to localised distension of the intrapulmonary arterial and venous circulations in a preparation in which the stimuli to other major reflexogenic areas ...

Should we measure the central venous pressure to guide fluid management? Ten answers to 10 questions

open access: yesCritical Care, 2018
The central venous pressure (CVP) is the most frequently used variable to guide fluid resuscitation in critically ill patients, although its use has been challenged.

Fluctuations of driving pressure during mechanical ventilation indicates elevated central venous pressure and poor outcomes

open access: yesPulmonary Circulation, 2020
Inappropriate mechanical ventilation may induce hemodynamic alterations through cardiopulmonary interactions. The aim of this study was to explore the relationship between airway pressure and central venous pressure during the first 72 h of mechanical ...

Retinal Vein Changes as a Biomarker to Guide Diagnosis and Management of Elevated Intracranial Pressure

open access: yesFrontiers in Neurology, 2021
Retinal vein changes, which can be observed on clinical exam or ophthalmic imaging, are promising non-invasive biomarkers for elevated intracranial pressure (ICP) as a complement to other markers of high ICP including optic nerve head swelling.
