Modeling the pulse signal by wave-shape function and analyzing by synchrosqueezing transform
, 2016 We apply the recently developed adaptive non-harmonic model based on the wave-shape function, as well as the time-frequency analysis tool called synchrosqueezing transform (SST) to model and analyze oscillatory physiological signals.

Left Ventricular Trabeculations Decrease the Wall Shear Stress and Increase the Intra-Ventricular Pressure Drop in CFD Simulations [PDF]
, 2018 The aim of the present study is to characterize the hemodynamics of left ventricular (LV) geometries to examine the impact of trabeculae and papillary muscles (PMs) on blood flow using high performance computing (HPC). Five pairs of detailed and smoothed

Computational Simulations for Aortic Coarctation: Representative Results From a Sampling of Patients [PDF]
, 2011 Treatments for coarctation of the aorta (CoA) can alleviate blood pressure (BP) gradients(D), but long-term morbidity still exists that can be explained by altered indices of hemodynamics and biomechanics.

The hemodynamics of counterpulsation
The Journal of Thoracic and Cardiovascular Surgery, 1966 Summary and conclusions 1. Synchronized counterpulsation was applied to two groups of 9 dogs with the use of a new fluid-coupled pulse generator. Multiple measurements were made of central (cardiac) and peripheral hemodynamics. 2. The counterpulsation pump performance was superior to pneumatically coupled systems previously studied.

Hemodynamic Monitoring Today [PDF]
Anesthesiology Research and Practice, 2011 Hemodynamic monitoring has been part of the routine management of intensive care patients and high risk surgical patients since the advent of the pulmonary artery catheter (PAC) more than thirty years ago. The growing availability of new less invasive devices over the past decades has now made it possible to monitor cardiac output (CO) more often in ...

Persistent Vascular Collagen Accumulation Alters Hemodynamic Recovery from Chronic Hypoxia [PDF]
, 2012 Pulmonary arterial hypertension (PAH) is caused by narrowing and stiffening of the pulmonary arteries that increase pulmonary vascular impedance (PVZ). In particular, small arteries narrow and large arteries stiffen. Large pulmonary artery (PA) stiffness

Seminars in Nephrology, 2005 Prolonged hyperuricemia is associated with the development of hypertension, renal arteriolosclerosis, glomerulosclerosis, and tubulointerstitial injury. It confers a greater risk than proteinuria for developing chronic renal disease and is associated with the development of hypertension.

Effective hemodynamic monitoring
Critical Care, 2022 AbstractHemodynamic monitoring is the centerpiece of patient monitoring in acute care settings. Its effectiveness in terms of improved patient outcomes is difficult to quantify. This review focused on effectiveness of monitoring-linked resuscitation strategies from: (1) process-specific monitoring that allows for non-specific prevention of new onset ...
