Correlation of systolic pressure variation, pulse pressure variation and stroke volume variation in different preload conditions following a single dose mannitol infusion in elective neurosurgical patients

open access: yesJournal of Neuroanaesthesiology and Critical Care, 2016
Background: A Prospective observational study was designed assess the correlation between arterial pressure waveform derived indices and echocardiography derived stroke volume variation (SVV) at different preload conditions in patients undergoing ...

Genome-wide association study identifies six new loci influencing pulse pressure and mean arterial pressure [PDF]

open access: yes, 2011
Numerous genetic loci have been associated with systolic blood pressure (SBP) and diastolic blood pressure (DBP) in Europeans1, 2, 3. We now report genome-wide association studies of pulse pressure (PP) and mean arterial pressure (MAP). In discovery (N =

Robust computation of pulse pressure variations [PDF]

open access: yesBiomedical Signal Processing and Control, 2018
Evidence of arterial pulse pressure variations caused by cardio-pulmonary interactions, and their connection to volume status via the Frank–Starling relationship, are well documented in the literature. Computation of pulse pressure variations from arterial pressure measurements is complicated by the fact that systolic and diastolic peaks are not evenly

Pulse pressure variation guided fluid therapy during kidney transplantation: a randomized controlled trial [PDF]

open access: yesBrazilian Journal of Anesthesiology, 2020
Purpose: Kidney transplantation is the gold-standard treatment for end stage renal disease. Although different hemodynamic variables, like central venous pressure and mean arterial pressure, have been used to guide volume replacement during surgery, the ...

2.2 TRANSFER FUNCTION-DERIVED CENTRAL PRESSURE AND CARDIOVASCULAR EVENTS: THE FRAMINGHAM HEART STUDY

open access: yesArtery Research, 2013
Relations between central versus brachial blood pressure and major cardiovascular disease (CVD) events remain controversial. Central measures derived using radial tonometry and a generalized transfer function as implemented using the SphygmoCor device ...

Cardiopulmonary interactions—which monitoring tools to use?

open access: yesFrontiers in Physiology, 2023
Heart-lung interactions occur due to the mechanical influence of intrathoracic pressure and lung volume changes on cardiac and circulatory function. These interactions manifest as respiratory fluctuations in venous, pulmonary, and arterial pressures ...

Pulse pressure variation, stroke volume variation and dynamic arterial elastance [PDF]

open access: yesCritical Care, 2011
We read with interest the recent article by Monge Garcia and colleagues [1]. We have two comments regarding this interesting physiological study. First, although we support their observation [2], their explanations may lead to some confusion. Indeed, the Edwards Vigileo™ system-FloTrac™ sensor calculates stroke volume (SV) using the equation:

Change in cardiac output during Trendelenburg maneuver is a reliable predictor of fluid responsiveness in patients with acute respiratory distress syndrome in the prone position under protective ventilation

open access: yesCritical Care, 2017
Background Predicting fluid responsiveness may help to avoid unnecessary fluid administration during acute respiratory distress syndrome (ARDS). The aim of this study was to evaluate the diagnostic performance of the following methods to predict fluid ...

Pulse pressure variation and stroke volume variation to predict fluid responsiveness in patients undergoing carotid endarterectomy [PDF]

open access: yesKorean Journal of Anesthesiology, 2013
BackgroundDuring carotid endarterectomy (CEA), hemodynamic stability and adequate fluid management are crucial to prevent perioperative cerebral stroke, myocardial infarction and hyperperfusion syndrome.

Vasodilation increases pulse pressure variation, mimicking hypovolemic status in rabbits

open access: yesClinics, 2010
OBJECTIVE: To test the hypothesis that pulse pressure respiratory variation (PPV) amplification, observed in hypovolemia, can also be observed during sodium nitroprusside (SNP)-induced vasodilation.
