Elbers and Ince have identified five classes of abnormal microcirculatory flow in<unk>  using side stream dark field microscopy. *Class I: all capillaries are stagnant when there is normal or sluggish venular flow. *Class II: there are empty capillaries next to capillaries that have flowing red blood cells. *Class III: there are stagnant capillaries next to capillaries with normal blood flow. *Class IV: hyperdynamic flow in capillaries adjacent to capillaries that are stagnant. *Class V: widespread hyperdynamic flow in the microcirculatory system. According to the cause, there are 4 types of<unk> : *Neurogenic shock: Decreased sympathetic stimulation leading to decreased vessel tone. *Anaphylactic shock *Septic shock *Shock due to adrenal crisis
