In decompensated shock, what happens to blood pressure?

In decompensated shock, the body's compensatory mechanisms fail to maintain adequate perfusion and blood pressure. During this stage, the heart's ability to pump effectively diminishes, and blood volume or systemic vascular resistance decreases, leading to a drop in blood pressure. As the body's tissues become progressively hypoperfused, the systolic blood pressure typically falls below the normal range, reflecting a critical state in which the body's organs are at risk of dysfunction or failure. This drop in blood pressure is a key indicator of decompensation and signifies that the patient is in a state of inadequate circulation that requires immediate medical intervention.
