shock

Shock refers to the severe pathological process of the whole body under the action of various strong pathogenic factors, the rapid decline of the body's circulatory function, the severe insufficiency of microcirculation of tissues and organs, as well as important vital organ functions and severe metabolic disorders. Common complications in the disease. The common feature of shock is that the effective circulation volume is insufficient, and the blood perfusion of tissues and cells is severely restricted despite compensation, which causes poor blood perfusion of tissues and organs throughout the body, leading to tissue hypoxia, microcirculation stasis, and organs. A series of pathophysiological changes such as dysfunction and abnormal metabolic function of cells. The pathogenesis of shock generally progresses from compensatory hypotension (reduced tissue perfusion) to microcirculation failure, which ultimately leads to cell membrane damage and cell death.
