Association of Intraoperative End-Tidal CO₂, Ventilation, and Hypotension With Postoperative Mortality in Noncardiac Surgery: A Retrospective Cohort Study.

Anesthesiology·September 10, 2026·PMID 42720197

Why it matters

Intraoperative ETco₂ is routinely monitored but often underutilized as a prognostic marker. This study suggests that low ETco₂ may signal risk beyond what blood pressure alone indicates, potentially aiding in postoperative risk stratification and early identification of high-risk patients.
