Symptoms include profuse bleeding, sweating, dizziness, confusion, and rapid/shallow breathing. The third main classification is distributive shock, which includes subclassifications of neurogenic, anaphylactic, and … Symptoms include instantaneous low blood pressure; warm, flushed skin due to sudden vasodilation, and slowed heart rate. Circulatory shock is the loss of intravascular volume and has two subclassifications, hypovolemic and obstructive. 0000002424 00000 n Shock, in physiology, failure of the circulatory system to supply sufficient blood to peripheral tissues to meet basic metabolic requirements for oxygen and nutrients and the incomplete removal of metabolic wastes from the affected tissues. Neurogenic shock is a distributed type that typically occurs after damage to the pathways of the central nervous system, particularly to the spinal cord. Treatment is aimed at combating the underlying infection and preventing organ damage. Enough fluid must be administered to keep the preload (ventricular filling pressure) sufficient and yet not too much to overburden an already taxed system.
