Reperfusion of blood flow is usually accompanied by circulatory shock.

The parasympathetic nervous system actively participates in the regulation of pathophysiologic responses in circulatory shock.

In patients with circulatory shock, monitoring of tissue perfusion requires assessment of systemic oxygen metabolism.

Then come profuse bleeding, circulatory shock and death.

The authors conclude that fluid resuscitation of circulatory shock with colloid solutions increases COP and requires less volume of resuscitative fluid.

Areas of ongoing research involve mediated-directed therapy, reperfusion injury, and immunologic interventions directed at reducing infectious complications in the survivors of circulatory shock.

Circulatory shock is a syndrome characterized by imbalance between oxygen supply and demand.
