What is the consequence of interrupting CPR for more than 10 seconds?

Interrupting CPR for more than 10 seconds is particularly detrimental to a patient in cardiac arrest because it significantly decreases the likelihood of restoring spontaneous circulation and can lead to worse neurological outcomes. Continuous high-quality chest compressions are crucial during cardiac arrest, as they help maintain perfusion to vital organs, particularly the brain and heart.

When CPR is interrupted, even briefly, it allows for a rapid decrease in blood flow, which can worsen the patient's condition. Research has shown that longer interruptions lead to poorer outcomes, highlighting the importance of minimizing any breaks in chest compressions. Therefore, while options related to ventilating and performing CPR before defibrillation have their place in the resuscitation process, choosing to stop CPR altogether when it is needed is the most harmful approach and goes against the guidelines for effective resuscitation.
