Arterial and Venous Pressure Monitoring during Cardiopulmonary Resuscitation for Out-of-Hospital Arrests: Four Case Reports

Journal of Vascular Diseases, 2023
Background: A new physiological monitoring system that simultaneously measures femoral arterial pressure, femoral venous pressure, and cerebral tissue oxygen saturation during CPR was used to evaluate the quality of cardiopulmonary resuscitation. In this

Function of arteries and veins in conditions of simulated cardiac arrest [PDF]

BioImpacts, 2021
Introduction: The study examined the behavior of vasculature in conditions of eliminated cardiac function using mathematical modeling. In addition, we addressed the question of whether the stretch-recoil capability of veins, at least in part accounts for

Correlation of Central with Jugular and Upper-limb Venous Pressure Measurements

Journal of Nepal Health Research Council, 2020
Background: Correlation data of different external reference points and methods used to measure venous pressures are scarce in the literature. We correlated central venous pressure with jugular venous pressure measured from sternal angle and with ...

The influence of spinal venous blood pressure on cerebrospinal fluid pressure

Scientific 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).

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

Stroke: 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

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

BMC 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.

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

, 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.

Comparison of vena cava distensibility index and pulse pressure variation for the evaluation of intravascular volume in critically ill children

Jornal de Pediatria, 2022
Objective: In this study, the authors aimed to evaluate the effectiveness of the vena cava distensibility index and pulse pressure variation as dynamic parameters for estimating intravascular volume in critically ill children.

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

, 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 ...
