What is the correct two-responder cycle for a child in CPR?

The correct two-responder cycle for performing CPR on a child involves delivering 15 compressions followed by 2 ventilations. This cycle is designed to provide effective and rapid circulation while also ensuring that the child is receiving adequate breaths to maintain oxygenation.

In the scenario of a child, the compression-to-ventilation ratio of 15:2 is used as a modification of adult CPR protocols. This adjustment recognizes the unique physiological needs of children, who may require a slightly different approach due to their smaller size and different lung capacity. The main goal is to maintain circulation and oxygenation as effectively as possible during a cardiac emergency.

Understanding the rationale behind the chosen ratio is crucial. The increased number of compressions compared to ventilations emphasizes the need to prioritize blood flow and perfusion in a child who may be more susceptible to rapid deterioration. This ensures that vital organs continue to receive blood and, subsequently, oxygen, while also providing necessary breaths to address any respiratory component of the emergency.

In contrast, other ratios do not align with current guidelines for pediatric CPR, either by emphasizing the ventilations too much or providing an insufficient number of compressions, potentially compromising the effectiveness of resuscitation efforts in young patients.
