In multiple-provider CPR for an infant, what is the correct compression-to-ventilation ratio?

In multiple-provider CPR for an infant, the correct compression-to-ventilation ratio is 15:2. This ratio is specifically designed to ensure that the airway is effectively managed while providing adequate chest compressions. During multiple-provider resuscitation, one rescuer focuses on delivering compressions, while the other provides ventilations.

The rationale behind using a 15:2 ratio is to balance the need for sufficient oxygenation (via ventilations) with the need to maintain adequate blood circulation (via compressions). The emphasis on a higher number of compressions compared to ventilations reflects the physiological demands of the infant's heart and body during cardiac arrest. Additionally, infants have a different anatomical and physiological makeup compared to older children and adults, which affects how CPR is performed on them, particularly emphasizing the need for more frequent compressions.

Maintaining this ratio is key to optimizing the effectiveness of CPR and improving the likelihood of a positive outcome in an infant experiencing cardiac arrest.
