摘要: An understanding of the hemodynamics cerebrovascular spasm following subarachnoid hemorrhage is important for diagnosis and treatment this potentially dangerous condition. overview model presented which includes main elements determining overall effect vasospasm. The included realistic pressureflow-velocity-diameter relationships encountered in a geometry resembling that vasospasm middle cerebral artery. Viscosity was adjusted to expected human blood. Furthermore, autoregulation included. effects induced hypertension as well hypotension were studied.
