Stroke volume estimation by thoracocardiography is better when glottis is closed [PDF]

Conference proceedings : Annual International Conference of the IEEE Engineering in Medicine and Biology Society. 2007 (2007) 1074-7, 2008
Thoracocardiography approach pretends to non-invasively monitor stroke volume by inductive plethysmographic recording of ventricular volume curves by a transducer placed on the chest. The purpose of this study was to investigate the potential of thoracocardiography to estimate stroke volumes while apnea with open glottis.

Predicting Clinical Outcome of Stroke Patients with Tractographic Feature [PDF]

, 2019
The volume of stroke lesion is the gold standard for predicting the clinical outcome of stroke patients. However, the presence of stroke lesion may cause neural disruptions to other brain regions, and these potentially damaged regions may affect the clinical outcome of stroke patients.

Dynamic and volumetric variables reliably predict fluid responsiveness in a porcine model with pleural effusion [PDF]

, 2013
Background: The ability of stroke volume variation (SVV), pulse pressure variation (PPV) and global end-diastolic volume (GEDV) for prediction of fluid responsiveness in presence of pleural effusion is unknown.

Relation between Neutrophil to Lymphocyte Ratio, Platelet to Lymphocyte Ratio and Cerebral Infarct Volume in patients with Ischemic Stroke.

Albanian Journal of Trauma and Emergency Surgery, 2021
:  Objectives: The activation of inflammatory processes in ischemic stroke might be important for the pathophysiological processes of ischemic stroke. The correlation between the Neutrophil to Lymphocyte Ratio (NLR), Platelet to Lymphocyte Ratio (PLR)

Role of atrial natriuretic peptide in the dissociation between flow relations with ventricular mass and function in a community with volume-dependent hypertension

Frontiers in Cardiovascular Medicine, 2023
BackgroundWhether differential effects of volume load on left ventricular mass (LVM) and function occur in sustained volume-dependent primary hypertension, and the impact of atrial natriuretic peptide (ANP) on these effects, is unknown.MethodsFrom aortic

Right ventricular stroke volume assessed by pulmonary artery pulse contour analysis

Intensive Care Medicine Experimental, 2020
Background Stroke volume measurement should provide estimates of acute treatment responses. The current pulse contour method estimates left ventricle stroke volume. Heart-lung interactions change right ventricular stroke volume acutely.
