Decompesatory mech (2)

General Medicine

Severe and prolonged hypotension triggers a cascade of physiological decompensatory mechanisms as the body's initial compensatory efforts fail. These include progressive vasodilation, myocardial depression, capillary leak syndrome, disseminated intravascular coagulation (DIC), metabolic derangements, and ultimately, multi-organ dysfunction. Therapeutic interventions focus on restoring adequate tissue perfusion and oxygen delivery by addressing the underlying causes and supporting cardiovascular function. Key principles involve maintaining adequate cardiac output, regulating blood volume and preload through fluid resuscitation, optimizing vasomotor tone and systemic vascular resistance with vasoconstrictors, ensuring sufficient blood pressure for vital organ perfusion, and addressing specific etiologies.
