Initially categorized into hypovolaemic, cardiogenic, and distributive shock, understanding of the pathophysiology has recently evolved such that tissue hypoperfusion in all shock states leads to a dysregulated inflammatory response. The effects of shock are initiallyreversible, but rapidly become irreversible, resulting in multi-organ failure (MOF) and death. Pathophysiology and compensatory mechanisms in Hypovolemic Shock In response to large-volume fluid loss, the body initiates physiological responses that act to maintain an adequate blood supply to essential organs. Close suggestions Search Search. Abstract. Treatment strategies have been developed based upon the understanding of these compensatory mechanisms. Shock is often defined as oxygen delivery to the tissue that is insufficient to meet tissue requirements. Collapse 5. Shock is prevented by Baroreceptor mechanism BP is mentained. This may be due to altered hemodynamics, such that the circulatory system is unable to provide adequate pressure to drive perfusion. COMPENSATORY MECHANISMS 1. shock caused by the heart failing to pump blood around the body-not enough blood being received by body . There are many types of shock. Decompensatory mechanisms. The first line of defense in maintaining cardiac output is tachycardia and this is often the first subtle sign of shock. In profound shock other autonomic mechanisms, primarily vagal, may come into play. The body compensates for volume loss by increasing heart rate and contractility , followed by baroreceptor activation resulting in sympathetic nervous system activation and peripheral vasoconstriction.

The development of shock initiates a cascade of responses in an effort to reestablish homeostasis. These 2 systems work synergistically to improve blood pressure and perfusion, and we will be walking through the steps the body takes to make this happen. Adreneric discharge 2. The compensatory stage is characterized by the employment of neural, hormonal, and biochemical mechanisms in the body's attempt to reverse the lactic acidosis. Compensatory Stage. when the bodies tissues and organs are not receiving enough blood-sudden drop in blood pressure.

Decreased anaerobic respiration cause tissue ischemia and hypoxia leading to anaerobic glycolysis, loss of energy and reduced protein synthesis, since ATP is not formed. Low arterial pressure triggers an adrenergic response with sympathetic-mediated vasoconstriction and often increased heart rate.
