Table 1 Determinant-based classification of acute pancreatitis severity

Classification	Mild AP	Moderate AP	Severe AP	Critical AP
(peri) Pancreatic necrosis	No	Sterile	Infected	Infected
Organ failure	No	(and/or) transient	(or) persistent	(and) persistent

AP: Acute pancreatitis.

Table 2 Modified Marshall Scoring System for organ failure

System	Score
	0	1	2	3	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, without inotropic support)	> 90	< 90	< 90	< 90	< 90
		Fluid responsive	Not fluid responsive	PH < 7.3	PH < 7.2

PaO₂: Partial pressure of oxygen; FiO₂: Fraction of inspiration O₂.
