Why the study?
Does a PaO2/FiO2 ratio < 202 at 3 hours after ICU admission predict mortality in patients immediately after cardiac surgery?
Population
2,725 consecutive cardiac surgery patients admitted to the ICU between 2004 and 2009.
Comparison
PaO2/FiO2 ratio < 202 at 3 hours after ICU… vs PaO2/FiO2 ratio > 242 or 202-242 at 3 hours…

May support early risk stratification after cardiac surgery; leaves open whether targeted interventions improve survival.
Does a PaO2/FiO2 ratio < 202 at 3 hours after ICU admission predict mortality in patients immediately after cardiac surgery?
A PaO2/FiO2 ratio < 202 at 3 hours post-ICU admission is a simple and strong predictor of both in-ICU mortality and worse long-term survival in cardiac surgery patients.
