How often should CPR be administered in cases of PEA?

In cases of pulseless electrical activity (PEA), it is crucial to understand the recommendations for cardiopulmonary resuscitation (CPR). CPR should be provided continuously, with high-quality compressions being delivered. The correct interval for reassessment and potentially changing the provider or for rhythm checks is every 2 minutes, leading to a more structured approach whereby CPR is typically administered for 1-2 minutes before reassessing the patient.

The guideline of performing CPR every 3-5 minutes does not align with the urgency required in resuscitating a patient in PEA. This condition is critical, and timely intervention is essential to maintain any residual blood flow and improve the likelihood of a return to spontaneous circulation. Continuous high-quality CPR is imperative, and reassessment should occur much more frequently, ideally every 2 minutes, to provide the best chance of survival. The other options fail to emphasize the immediacy required in such situations.
