TABLE 4

Modified Marshall scoring system for organ failure

	Respiratory	Renal	Cardiovascular
Score^{^a}	PaO₂/FiO₂^{^b}	Serum creatinine (mg/dL)	Systolic blood pressure (mm Hg)
0	> 400	≤ 1.4	> 90
1	301–400	1.5–1.8	< 90 and responding to fluid resuscitation
2	201–300	1.9–3.5	< 90 and not responding to fluid resuscitation
3	101–200	3.6–4.9	< 90 with pH < 7.3
4	≤ 100	≥ 5	< 90 with pH < 7.2

↵a A score of 2 or more indicates organ failure. Persistent failure is considered organ failure lasting longer than 48 hours.
↵b Ratio of partial pressure of arterial oxygen to fractional inspired oxygen.
