| Respiratory (PaO2/FiO2) (mmHg) | ≥400 | 300-400 | 200-300 | 100-200 and mechanical ventilation | <100 and mechanical ventilation |
| Neurological (GCS) | >14 | 13-14 | 10-12 | 6-9 | <6 |
| Cardiovascular (MAP or vasopressor¶) | MAP ≥70 | MAP <70 | Dop ≤5 or dob (any dose) | Dop >5 or epi ≤0.1 or nor ≤0.1 | Dop >15 or epi >0.1 or nor >0.1 |
| Liver [Bilirubin (μmol/L)] | <20 | 20-32 | 33-101 | 102-204 | >204 |

¶, vasopressor drug doses are in µg/kg/min. GCS, Glasgow coma scale; MAP, mean arterial pressure; Dop, dopamine; dob, dobutamine; epi, epinephrine; nor, norepinephrine.
