After surviving cardiac arrest, patients typically receive sedation (sleep medicine) in the hospital while their body recovers. This study is looking at brain monitoring tools—like brain wave recordings, pupil measurements, and ultrasound—to understand which patients might wake up successfully early (within 6 hours) versus later. The goal is to help doctors decide how long to keep patients sedated and predict who will have the best chance of recovery.
Doctors aren't sure how long to keep cardiac arrest survivors sedated, because sedation can protect the brain but can also cause problems like infections and longer hospital stays. This study will help doctors use brain monitoring information to make better decisions about when to let patients wake up and which patients are most likely to recover well.

You will be part of a larger study where some patients wake up from sedation within 6 hours and others after 28-36 hours. During this substudy, doctors will use special monitoring tools to measure your brain activity (EEG), check your pupils' responses, and use ultrasound to look at blood flow in your brain—all to understand what these measurements tell us about who wakes up successfully. These are monitoring and observation tests only; you won't be taking an experimental medication.
