What type of shock is characterized by altered blood vessel tone leading to low blood pressure?

Distributive shock is characterized by altered blood vessel tone, which leads to a significant drop in blood pressure. This type of shock occurs when there is widespread vasodilation, often due to systemic causes such as sepsis, anaphylaxis, or neurogenic factors, resulting in inadequate blood flow to the organs despite the total blood volume being normal or even increased. The inability of blood vessels to constrict properly causes blood to pool in the extremities, thereby reducing venous return to the heart and ultimately leading to hypotension. Understanding this mechanism is crucial for recognizing and treating distributive shock effectively, as the underlying cause must be addressed to restore vascular tone and stabilize blood pressure.
