Modified Marshall Scoring System for organ dysfunction
| Organ system Involved | Score = 0 | Score = 1 | Score = 2 | Score = 3 | Score = 4 |
|---|---|---|---|---|---|
| Respiratory (PaO2/FIO2) | >400 | 301–400 | 201–300 | 101–200 | ≤101 |
| Renal (serum creatinine, mg/dL) | <1.4 | 1.4–1.8 | 1.9–3.6 | 3.6–4.9 | >4.9 |
| Cardiovascular (systolic blood pressure, mmHg) | >90 | <90 | <90 | <90 | <90 |
| Responsive to fluid resuscitation | Not responsive to fluid resuscitation | pH < 7.3 | pH < 7.2 |
FIO2 = fraction of inspired oxygen; PaO2 = partial pressure of oxygen in arterial blood
