Subarachnoid Hemorrhage, Aneurysmal- Non-Invasive Near-infrared Spectroscopy (NIRS) device (HEM1 with Foresight Elite Sensor)
brief summary
The goal of this observational study is to continuously assess cerebral autoregulation in patients with subarachnoid hemorrhage (SAH) using cerebral oximetry index (COx) and hemoglobin volume reactivity index (HVx). The main question it aims to answer is: Whether optimal perfusion pressure is dynamic and changes with time in patients with SAH, and that autoregulation is disrupted in patients during the course of SAH, contributing to delayed cerebral ischemia (DCI).
