What is the correct compression-to-ventilation ratio for child or infant multiple-provider CPR?

The compression-to-ventilation ratio for child or infant multiple-provider CPR is 15:2. This ratio signifies the importance of providing a greater number of compressions relative to ventilations during CPR in infants and children, when performed by multiple rescuers. The focus on this specific ratio helps to ensure that adequate blood flow is maintained while also providing necessary oxygenation.

In a multiple-provider scenario, the emphasis is on maintaining high-quality chest compressions, which are critical to perfusion. After every 15 compressions, the providers deliver 2 rescue breaths to help restore the victim's oxygen levels. This balance of compressions and ventilations is essential for promoting effective resuscitation in pediatric patients, who may require more rapid replenishment of oxygen compared to adults due to their physiology.

The other options reflect ratios that are either suitable for adult CPR or do not align with the current recommendations for pediatric care, demonstrating the tailored approach to CPR based on the age and needs of the victim. Knowing the correct ratio enhances the understanding and application of life-saving techniques during a medical emergency involving children or infants.
