Circulatory shock represents a critical state of decreased tissue perfusion resulting from inadequate systemic blood pressure and impaired oxygen delivery to the tissues. Pathophysiologically, it involves a breakdown of vascular tone and fluid balance, leading to systemic vasodilation and increased capillary permeability. This allows plasma components to leak out of the circulatory system into the interstitial space, significantly decreasing the effective circulating blood volume. The core manifestations include profound hypotension and an inability of the cardiovascular system to maintain sufficient cardiac output despite compensatory efforts. Effective management focuses on restoring intravascular volume, maintaining peripheral vascular resistance, and supporting oxygen delivery to vital organs to prevent irreversible cellular damage and metabolic failure.
