Relative indexes of cutaneous blood perfusion measured by real-time laser Doppler imaging (LDI) in healthy volunteers

We used real-time LDI to study regional variations in microcirculatory perfusion in healthy candidates to establish a new methodology for global perfusion body mapping that is based on intra-individual perfusion index ratios. Our study included 74 (37 fema ...

The effect of continuous positive airway pressure on total cerebral blood flow in healthy awake volunteers

Nikolaos Stergiopoulos, Bryn Andrew Martin

Continuous positive airway pressure (CPAP) is the gold standard treatment for obstructive sleep apnea. However, the physiologic impact of CPAP on cerebral blood flow (CBF) is not well established. Ultrasound can be used to estimate CBF, but there is no wid ...

Systolic Hypertension Mechanisms: Effect of Global and Local Proximal Aorta Stiffening on Pulse Pressure

Nikolaos Stergiopoulos, Philippe Reymond, Nico Westerhof

Decrease in arterial compliance leads to an increased pulse pressure, as explained by the Windkessel effect. Pressure waveform is the sum of a forward running and a backward running or reflected pressure wave. When the arterial system stiffens, as a result ...

Pressure and Flow Wave Propagation in Patient-Specific Models of the Arterial Tree

Philippe Reymond

Blood flow in the arterial circulation induces hemodynamic forces that play an important role in various forms of vascular diseases. Temporal variation of the wall shear stress seems to play a significant role in atherogenesis and plaque stability. Flow in ...

Pulse generator for trauma patient simulator

Madge Audrey Marie Martin

Developing a Trauma Patient Simulator is a very ambitious project that goes far beyond what can be expected for a master thesis. Therefore, it has been decided to focus on blood circulation which is one of the three vital functions described in the first a ...

Mathematical modelling of the cardiovascular system and skeletal muscle interaction during exercise

Carlo D'Angelo

In this work we present a mathematical model for the coupling of cardiovascular system and metabolism under sport efforts. Effects such as oxygenation, heart rates, flow rates, blood pressure and mass transfer to tissues will be considered. A special atten ...
