Monitoring brain activity and oxygen levels in ARDS patients in the ICU
Official title: Depth of Sedation and Its Impact on Cerebrovascular Reactivity in Acute Respiratory Distress Syndrome: a Pilot Analysis
Run by University of Manitoba · NCT05847634 · Data updated 2026-11-12
This study is testing if new non-invasive methods can help doctors find the right level of sedation for patients with acute respiratory distress syndrome in the ICU by monitoring their brain activity and oxygen levels.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adult patients admitted to the ICU with confirmed ARDS requiring deep sedation and/or neuromuscular blockade.
✕Probably not a fit
Patients who have been in the ICU for more than 24 hours or are deemed to have imminent death will not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study investigates the feasibility of using non-invasive monitoring techniques, specifically processed electroencephalography (EEG) and near-infrared spectroscopy (NIRS), to assess the optimal depth of sedation in patients with acute respiratory distress syndrome (ARDS) in the intensive care unit (ICU). The research aims to determine how these monitoring methods can help minimize the correlation between brain oxygenation and sedation levels. Data collected will include demographic information, medical history, and sedation dosages, allowing for a comprehensive analysis of sedation effects on cerebrovascular reactivity in ARDS patients.
Why it matters
Potential benefit: If successful, this study could lead to improved sedation management in ARDS patients, enhancing their recovery and outcomes.
How similar studies have gone: While this approach is novel in the context of ARDS, similar monitoring techniques have shown promise in other critical care settings.
