Table 1 Classifying microcirculatory flow abnormalities in distributive shock

Class	Capillary hemodynamics	Disease states observed in
I	Stagnant	Pressure guided resuscitation from sepsis
II	Continuous/capillary fall-out	On-pump CABG surgery, ECMO
III	Continuous/stagnant	Resuscitated sepsis, reperfusion injury, sickle cell crises, malaria
IV	Hyperdynamic/stagnant	Resuscitated sepsis
V	Hyperdynamic	Resuscitated sepsis, exercise

CABG, coronary artery bypass grafting; ECMO, extracorporeal membrane oxygenation.
