When should CPR be initiated on a trauma patient?

Initiating CPR on a trauma patient is crucial when there is a mismatch between the mechanism of injury and the patient's clinical condition. This discrepancy often indicates that the patient may be in a life-threatening state, even if they appear stable at first glance. For example, a severe impact might lead to significant internal bleeding or cardiac arrest that isn't immediately obvious through external assessments. Starting CPR in this scenario could mean the difference between life and death, as immediate intervention may restore circulation and improve outcomes.

While other situations may warrant attention, they do not provide the same urgency that a mismatch between mechanism of injury and clinical presentation does. Identifying this situation allows responders to act quickly, conducting further assessments and administering necessary life support when it is most needed.
