After performing CPR for 18 minutes, what should the current compressor do if they feel exhausted?

When a person is performing CPR, it is essential to maintain high-quality chest compressions to ensure that blood is effectively circulated to the brain and vital organs. After an extended period of performing chest compressions, especially as long as 18 minutes, exhaustion can significantly reduce the effectiveness of the compressions.

The best practice in this scenario is to switch out with another Basic Life Support (BLS) provider. When providers rotate, it allows for continued high-quality compressions without a significant interruption in the flow or quality of chest compressions. This ensures that the victim receives the best possible care and increases the chances of a positive outcome.

Taking a break and stopping CPR, while potentially providing a temporary rest, is not a safe option because it would mean no compressions are being delivered, which can be detrimental to the patient. Continuing compressions without a break by the exhausted provider would likely reduce the quality of the compressions due to fatigue. Asking for help from bystanders is not the most efficient course of action when a specialized provider is available to take over the compressions effectively. Switching ensures that CPR continues seamlessly and effectively.
