O2ER is derived entity using the formula O2ER = (SaO2- SvO2)/SaO2.
The EF-associated abdominal sepsis was treated according to standards: (1) adjustment for fluid and electrolyte imbalance; (2) norepinephrine (intravenously, 10 [micro]g/min, 3 h) as primary vasopressor; (3) early goal-directed therapy (MAP > 65mmHg, and SvO2 > 65%); (4) source control by surgical or percutaneous drainage; (5) antibiotics therapy.
In critically ill patients, untreated AF can cause hypotension (mean arterial pressure < 65mmHg), myocardial ischemia, and heart failure (pulmonary edema, cardiogenic shock) with subsequent tissue hypoxia (SvO2 < 65%, lactate > 2.0 mmol/l) and organ dysfunction (encephalopathy, acute kidney injury with urine output < 0.5mL/kg/h and liver dysfunction).
