Head Position on Cerebral Haemodynamics in Acute Ischemic Stroke and Controls


Phase N/A Results N/A

Summary of Purpose

Cerebral autoregulation is an important mechanism whereby cerebral perfusion is normally maintained at a constant level, over a relatively wide blood pressure range. It can be assessed noninvasively by the use of Trans Cranial Doppler (TCD). This means using ultrasound probes over both sides of the head to measure changes in blood flow in one of the main brain arteries (the middle cerebral artery) in response to...
