Etiology of Shock	Cardiac Index (CI)	Systemic Vascular Resistance (SVR)	Central Venous O2 Saturation (ScVO2)	Central Venous Pressure (CVP)
Cardiogenic	Decreased	Increased	Decreased	Increased
Distributive	Increased or normal	Decreased	Increased	Decreased or normal
Hypovolemic	Decreased	Increased	Decreased	Decreased
Obstructive	Decreased	Increased or normal	Decreased or normal	Increased
Mixed Cardiogenic & Distributive	Decreased or variable	Decreased or variable	Variable	Variable
