Summary
Cerebral autoregulation, the brain's blood pressure control, has fast and slow components. Systems analysis of middle cerebral artery velocity and blood pressure reveals impaired autoregulation in patients with subarachnoid hemorrhage.
Area of Science:
- Neuroscience
- Physiology
- Medical Engineering
Background:
- Cerebral autoregulation maintains stable brain blood flow despite blood pressure changes.
- It involves complex fast and slow physiological components.
- Understanding its temporal dynamics is crucial for managing neurological conditions.
