Why the study?
Does increasing PEEP to 12 cmH2O affect hemodynamics and central venous oxygen saturation in hypoxemic patients after coronary artery bypass surgery?
Population
70 post-cardiac surgery patients, mean age 61 ± 7 years, without ventricular dysfunction, with hypoxemia.
Comparison
Positive end-expiratory pressure increased to 12… vs Baseline PEEP (PEEP 5 cmH2O).
Design
Cohort
Follow-up
30 minutes

May warrant ScvO2 and lactate monitoring during PEEP titration post-CABG; hypothesis-generating for tissue perfusion effects.
Does increasing PEEP to 12 cmH2O affect hemodynamics and central venous oxygen saturation in hypoxemic patients after coronary artery bypass surgery?
Increasing PEEP in hypoxemic post-CABG patients improves arterial oxygenation but may impair peripheral tissue oxygenation, highlighting the need to monitor peripheral parameters during such interventions.
