JUgular Gating for Upright Level Adjustment and Targeted Enhancement of Cerebral Perfusion
Sponsor: University Hospital, Bordeaux
Summary
Investigators aim to demonstrate that the evolution of intracranial pressure (ICP) is nonlinear and may be influenced by jugular vein collapse. This collapse is estimated to occur at the angle where the hydrostatic pressure of the blood column matches the central venous pressure, and it can be assessed using ultrasonography. This approach allows for the determination of an individualized tilt angle, optimizing cerebral perfusion pressure without compromising venous drainage.

Ultrasound assessment
After the routine nursing care, during patient repositioning to 30 ° assessments are performed at 0, 10° 20° 30°, and at a calculated threshold angle α. At each angle intracranial pressure , cerebral perfusion pressure and ultrasound assessment of cerebral blood flow velocities and internal jugular vein cross-sectional area at three cervical levels are recorded.
