During multiple-provider CPR for an infant, the correct compression-to-ventilation ratio is 15:2. This ratio is specifically designed to ensure that infants receive an adequate number of ventilations in relation to chest compressions. The reasoning behind this ratio is based on the physiology of infants, who have a higher need for ventilation compared to adults due to their vulnerability and differences in respiratory anatomy.

Moreover, in a multiple-provider scenario, two rescuers can effectively manage the rhythm of compressions and ventilations by performing 15 compressions followed by 2 breaths, allowing for better oxygenation while maintaining effective circulation. This is essential in providing the best chances of survival in infants during cardiac arrest, as their smaller bodies require adjustments in the approach to CPR compared to older children and adults.

Choosing any other compression-to-ventilation ratio would not adequately meet the needs of an infant, potentially compromising their chances of a successful resuscitation.
