Noninvasive Assessment of Cerebral Oxygenation and Cardiac Function in Patients With Neurovascular Diseases

Noninvasive Assessment of Cerebral Oxygenation and Cardiac Function in Patients With Neurovascular Diseases

This prospective observational study will assess the regional cerebral oxygen saturation and cardiac output non-invasively in patients with subarachnoid hemorrhage during nimodipine administration for the prevention/management of cerebral vasospasm.

Inclusion Criteria:

• aneurysmal subarachnoid hemorrhage
• potential or actual cerebral vasospasm

Exclusion Criteria:

• non-aneurysmal subarachnoid hemorrhage
• outside the 4-21 day window after ictus
• peripheral deoxygenation
• contraindication for nimodipine administration
