Shock (circulatory collapse)
Shock is a state of inadequate blood flow and oxygen delivery to tissues, leading to cellular dysfunction and, if uncorrected, organ failure and death. It has several forms, including hypovolemic (blood or fluid loss), distributive (sepsis or anaphylaxis), cardiogenic (heart failure), and obstructive. Signs include pale gums, rapid weak pulse, cold extremities, and collapse. Shock is a critical emergency requiring rapid restoration of circulation and treatment of the underlying cause.
