Interruptions during chest compressions negatively impact the effectiveness of cardiopulmonary resuscitation. The primary aim of high-quality CPR is to maintain consistent blood flow to the brain and heart. Any cessation, even brief, diminishes this critical perfusion, potentially reducing the likelihood of successful resuscitation.
Minimizing interruptions is vital because blood flow decreases significantly during pauses. The heart requires time to refill with blood during the relaxation phase between compressions. Extended breaks prevent adequate refilling, leading to reduced cardiac output upon resumption of compressions. Historically, CPR protocols often included frequent pauses for pulse checks or ventilation, but current guidelines emphasize continuous compressions with minimal disruption. The fewer and shorter the interruptions, the better the outcomes for the patient.
