About This Trial
The goal of this observational study is to determine the correlation between cerebral oxygenation values measured by near-infrared spectroscopy (NIRS) and other routine monitoring parameters in patients placed in the semi-sitting position.
The primary questions investigated are :
Do NIRS values correlate with heart rate, invasive mean arterial pressure, and end-tidal carbon dioxide?
Do NIRS val…
