When providing CPR to an infant with two providers, what is the recommended compression to ventilation ratio?

The recommended compression to ventilation ratio when providing CPR to an infant with two providers is 15:2. This ratio allows for an effective balance of chest compressions and ventilations, which is crucial in maintaining blood circulation and providing oxygen to the infant's body during cardiac arrest.

Using two providers, one can perform compressions while the other manages the ventilations, ensuring that both components of CPR are adequately addressed. The method of using two thumbs encircling the chest is emphasized because it can enhance the effectiveness of compressions and allows for better stability and control. This technique allows the provider delivering compressions to maintain a good position while also ensuring that the chest is compressed adequately to generate blood flow.

In contrast, other options suggest different ratios or compression techniques that may not provide the same level of efficacy for infants during CPR. For instance, a 30:2 ratio is more appropriate for adults or children, while a single provider method would not take full advantage of the benefits of teamwork and optimal technique that the two-provider system offers.
