When should CPR be paused during the resuscitation process?

The correct response highlights that CPR should only be paused for specific critical reasons: for defibrillation or when switching rescuers.

In a resuscitation scenario, it’s essential to maintain continuous high-quality chest compressions, as interruptions can significantly reduce the chances of survival. When a person is in a cardiac arrest, every second counts, and maintaining perfusion to vital organs is crucial.

Defibrillation is a rare exception in that it momentarily halts compressions to allow the defibrillator to deliver a shock to the heart, which can potentially restore a normal heart rhythm. Switching rescuers is another permissible pause, primarily to prevent fatigue in the individual performing chest compressions. This ensures that compressions remain effective and the responder can maintain sufficient energy and focus throughout the resuscitation process.

Other situations, such as checking for a pulse or assessing the effectiveness of CPR, would introduce unnecessary delays that could compromise the efficacy of resuscitation efforts. These actions can be done while ongoing compressions are provided or simultaneously with other interventions, emphasizing the importance of sustained cardiac support during the critical moments of a cardiac arrest.
