What should be done if a patient is found unconscious and not breathing?

When a patient is found unconscious and not breathing, starting high-quality CPR immediately is the most critical intervention. CPR helps to maintain vital blood flow to the brain and organs by manually pumping the heart and providing oxygenation through rescue breaths when appropriate.

In this scenario, the immediate priority is to ensure that the patient's circulation and oxygenation are restored as quickly as possible, which makes CPR the first course of action. The effectiveness of CPR can significantly increase a patient’s chance of survival until emergency medical services (EMS) arrive or the patient is otherwise stabilized.

The need for prompt action is underscored by the fact that a patient who is not breathing is at high risk for brain damage and death due to the lack of oxygen. Therefore, initiating CPR without delay is essential in this life-threatening situation. Other interventions, such as administering oxygen or checking vital signs like blood pressure, can only occur once CPR is underway and the primary airway and circulation efforts are being made.
