In vivo cerebral blood flow autoregulation studies using rheoencephalography

Acute management of patients with traumatic brain/blast injury is a challenge. To minimize secondary injury and improve outcome, it is critical to detect neurological deterioration early, when it is potentially reversible. One potential monitoring method is cerebral electrical impedance (rheoencephalography-REG) because of its non-invasiveness and good time resolution. Reported here are the res...

Magnetic resonance techniques to measure distribution of cerebral blood flow

The human arterial tree system is crucial for the delivery of oxygen and nutrients to the cells. For critical organs like the brain and the spinal cord the vascular system is designed in a way to ensure sufficient oxygen transportation to this particular tissue. This is usually achieved by having backup vessels (so-called collaterals) and connections (communicating arteries) between major arter...

Modelling of impaired cerebral blood flow due to gaseous emboli.

Bubbles introduced to the arterial circulation during invasive medical procedures can have devastating consequences for brain function but their effects are currently difficult to quantify. Here we present a Monte Carlo simulation investigating the impact of gas bubbles on cerebral blood flow. For the first time, this model includes realistic adhesion forces, bubble deformation, fluid dynamical...

Modelling cerebral blood flow autoregulation in humans

Better understanding of the determinants of cerebral blood flow (CBF) and the interpretation of clinical measurements can benefit from quantitative modelling of CBF regulatory mechanisms and their interaction with other haemodynamic variables such as intracranial pressure and blood gases. Mathematical models have been able to reproduce many known phenomena and to extract relevant parameters for...

The Effect of Hurdling Performance on The Adaptive Profile of Cerebral Blood Flow in Vestibular Irritation

Background: The reactions of the whole organism that occur under the action of accelerations of rectilinear and rotational motion are factors that have a systemic effect on the cerebral blood flow. The use of hurdling performance in the structure of human physical activity can have a significant impact on the tone of the brain vessels, their elasticity and venous outflow in the development of f...
