Overview of definitions of vasoplegia used and their criteria

	Vasodilation criterion	Hemodynamic criterion	Vasopressor criterion	Preload criterion	Time moment/period
Argenziano [1]	MAP < 70 mmHg	CI > 2.5 l·min− 1·m− 2	nor > 8 μg·min− 1		5 min after CPB
Levin [2]	MAP < 50 mmHg and SVR < 800 dynes·s·cm− 5	CI > 2.5 l·min− 1·m− 2	any vasopressor	CVP < 5 mmHg and PCWP < 10 mmHg	first 3 h after ICU arrival
Patarroyo [9]	SVR < 800 dynes·s·cm− 5	CI > 2.5 l·min− 1·m− 2	≥ 2 vasopressors: 1. epi > 4 μg/min, 2. nor ≥4 μg/min, 3. dopa ≥5 μg· kg− 1·min− 1, 4. vasopressin ≥1 U/hr		6–48 h after ICU arrival
Unified definition	MAP < 50 mmHg or SVR < 800 dynes·s·cm− 5	CI > 2.5 l·min− 1·m− 2	nor > 200 ng·kg− 1·min− 1 or equivalent doses of other vasopressors: epi ≥ 200 ng·kg− 1·min− 1; dopa ≥30 μg·kg− 1·min− 1; phenyl ≥2 μg·kg− 1·min− 1; or vasopressin ≥0.08 U·min− 1		first 48 h after ICU arrival
