What is the correct compression to ventilation ratio for infant 1 rescuer CPR?

30 compressions to 2 ventilations
15 compressions to 2 ventilations
10 compressions to 2 ventilations
20 compressions to 2 ventilations

The correct answer is: 30 compressions to 2 ventilations

In the context of infant CPR performed by a single rescuer, the established guideline is a compression to ventilation ratio of 30 compressions to 2 ventilations. This ratio is designed to ensure that the infant receives adequate chest compressions to maintain blood circulation while also providing enough rescue breaths to oxygenate the blood. During CPR, it is crucial to maintain a high-quality compression rate of 100 to 120 compressions per minute while simultaneously providing breaths that are effective enough to create visible chest rise. Utilizing the 30:2 ratio allows for a balanced approach where the rescuer can effectively support circulation through compressions while also ensuring sufficient oxygen delivery during the brief ventilation phases. The other ratios listed do not align with nationally recognized guidelines, making the 30:2 ratio the appropriate choice for infant CPR in a single-rescuer scenario.
