a The PO2/FIO2 ratio is calculated without reference to the use or mode of mechanical ventilation, and without reference to the use or level of positive end-expiratory
pressure: b The serum creatinine concentration is measured in μmol/L without reference to the use of dialysis; c the serum bilirubin concentration is measured in μmol/L d the pressure-adjusted heart rate (PAR) is calculated as the product of the heart rate (HR) multiplied by the ratio of the right atrial (central venous ) pressure (RAP) to the
mean arterial pressure (MAP): PAR= HR × RAP/ mean BP; e the platelet count is measured in platelets/ml 10-3; f the Glasgow coma Score is preferably calculated by the
patient’s nurse, and is scored conservatively (for the patient receiving sedation or muscle relaxants, normal function is assumed, unless there is evidence of intrinsically
altered mentation) |
