  1. All clinical situations represent patients in the ICU, who have been invasively mechanically ventilated for at least 5 days, with FiO2 set at 50%. ARDS = patient with acute respiratory distress syndrome and pneumonia; cardiac ischemia = patient with signs of cardiac ischemia (ST-depressions in the anterior leads [max 3 mm]) and pneumonia; cerebral ischemia = patient with recent cerebral ischemia and one-sided hemiplegia; sepsis = patient with a liver abscess and sepsis; untreatable anemia = Jehovah's Witness with stable hemoglobin of 1.8 mmol/L after gastric bleeding; higher = increase FiO2, higher than current 50%; unchanged = maintain FiO2 at current 50%; lower = decrease FiO2, lower than current 50%.
