The goal of this observational study is to learn about the influence of extracellular water on volume status in adult patients with intracranial hemorrhage presenting with hemodynamic instability. The main question it aims to answer is:
• Can measurement of extracellular water contribute to the description of hemodynamic instability in adult patients with intracranial hemorrhage. Patients with intracranial hemorrhage admitted to intensive care will receive standard care with the addition of measurement of extracellular water.
Adults with intracranial hemorrhage admitted to ICU.
Pregnancy, palliative care.
