Estimating coupling directions in the cardio-respiratory system using recurrence properties [PDF]
, 2013 The asymmetry of coupling between complex systems can be studied by conditional probabilities of recurrence, which can be estimated by joint recurrence plots. This approach is applied for the first time on experimental data: time series of the human cardio-respiratory system in order to investigate the couplings between heart rate, mean arterial blood ...

Relationship between blood pressure and flow rate in arteries using a modified Windkessel model [PDF]
arXiv, 2020 This study examined the flow rate in arteries using the modified Windkessel model, considering various models for blood pressure. An exact solution was derived using a Laplace transform method and the effects of blood pressure on the flow rate in an artery were examined.

Investigation the Effect of Velocity inlet and Carrying Fluid on the Flow inside Coronary Artery [PDF]
arXiv, 2021 In this study OpenFOAM 4.4.2 was used to investigate flow inside the coronary artery of the heart. This step is the first step of our future project, which is to include conjugate heat transfer of the heart with three main coronary arteries. Three different velocities were used as inlet boundary conditions to see the effect of velocity increase on ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Music interventions have been shown to have beneficial effects on hemodynamic parameters, pain, and anxiety in various medical settings. However, music interventions in the setting of acute stroke have not been studied. The objective of this trial was to perform a pilot feasibility study of music interventions in the setting of acute

The role of risk factors and endothelium dysfunction in the pathogenesis of the high normal arterial preassure and clinical signs of the vegetative disturbances in children [PDF]
Системные гипертензии, 2015 As a result of investigation of the children the dysfunction of endothelium at high normal arterial pressure is the cause of the hemodynamic disturbances of children, equal of the arterial hypertension.

Arterial Tube Laws and Wave Speeds [PDF]
arXiv, 2021 The 1-D theory of flow in the arteries yields an equation for the wave speed in terms of the density of blood and the distensibility of the vessel. By means of this equation there is a duality between the equation for the wave speed and the tube law describing the area of the vessel as a function of pressure.

Metabolic Consequences of Rheumatoid Arthritis
Arthritis Care &Research, EarlyView.Patients with rheumatoid arthritis (RA) may have metabolic disruption, which can contribute to adverse long‐term outcomes, for multiple reasons. Patients with RA appear to have a higher risk of sarcopenia, type 1 and type 2 diabetes mellitus, metabolic syndrome, and hypertension. Systemic inflammation in RA can cause a “lipid paradox,” with reduced low‐
