Tactical Combat Casualty Care – Combat Medic/Corpsman (TCCC‑CMC) Practice Test

Low blood pressure and increased heart rate are both significant indicators of hemorrhagic shock. When a person experiences significant blood loss, their body attempts to compensate for the decreased volume and pressure by increasing heart rate, a response driven by the autonomic nervous system to maintain adequate blood flow to vital organs.

Low blood pressure occurs as the volume of circulating blood decreases, leading to inadequate perfusion of tissues and organs. This is particularly concerning in cases of hemorrhagic shock, where the loss of blood volume can be significant and rapid.

In contrast, while high fever can indicate infection or other medical issues, it is not directly associated with hemorrhagic shock. Therefore, recognizing the combination of low blood pressure and increased heart rate as signs of this condition is crucial for effective assessment and intervention in trauma cases.
