In a two-person adult CPR scenario, which ratio corresponds to the recommended compressions to ventilations?

Two-person adult CPR aims to maximize blood flow while maintaining oxygenation. The recommended pattern is 30 chest compressions followed by 2 rescue breaths, then repeat. This ratio provides a strong, continuous perfusion of the heart and brain through the compressions, while the two breaths restore oxygen content without causing long interruptions. In a two-rescuer scenario, one person performs compressions while the other delivers the two breaths, switching roles after each cycle to keep the tempo steady. Ratios with fewer compressions between breaths or with longer pauses between breaths disrupt circulation and reduce effectiveness, so they’re not used. This 30:2 rhythm is the standard for adult two-person CPR.
