Shock is a life-threatening condition that occurs when the body’s tissues and organs do not receive adequate oxygen and blood flow. Left untreated, shock leads to organ failure, irreversible injury, and death. 

Early recognition is one of the most important responsibilities of the trauma provider. Trauma patients often compensate for blood loss, making early signs of shock subtle and easy to miss.

Common indicators of shock include:

• Altered mental status
• Anxiety or restlessness
• Pale, cool, or clammy skin
• Tachycardia
• Weak peripheral pulses
• Delayed capillary refill
• Increasing respiratory rate
• Hypotension (late finding)

Shock is not defined by blood pressure alone. A patient may be in shock long before hypotension develops. Mental status, pulse quality, and skin signs often provide the earliest clues to circulatory compromise. 

In trauma patients, shock is most commonly caused by hemorrhage, but other causes may be present depending on the injuries sustained. 

Early recognition, prompt intervention, and continuous reassessment are the keys to successful management.

Remember: Patients do not suddenly become hypotensive. The body gives warning signs. Learn to recognize them early.
