Multimodal pressure-flow method to assess dynamics of cerebral autoregulation in stroke and hypertension

Multimodal pressure-flow method to assess dynamics of cerebral autoregulation in stroke and hypertension

<p>Abstract</p> <p>Background</p> <p>This study evaluated the effects of stroke on<b/> regulation of cerebral blood flow in response to fluctuations in systemic blood pressure (BP). The autoregulatory dynamics are difficult to assess because of the nonstationarity...
