Overview

This study is designed as a prospective, non-randomized, observational clinical study. The study will collect clinical and rrEEG (Ceribell EEG) data when monitoring subjects for delirium subtypes. EEG and clinical data will be collected for the development of future software algorithms to assess the presence and severity of delirium.
