What is the correct compression to ventilation ratio for CPR in newborns?

The correct compression to ventilation ratio for CPR in newborns is 3:1. This means that for every three chest compressions, you should provide one breath. This ratio is particularly important in neonatal resuscitation because newborns require both effective chest compressions and adequate ventilation to optimize their chances of survival in cases of cardiac arrest.

Newborns have different physiological needs compared to older children and adults; their smaller body size and unique respiratory management necessitate a specific approach to CPR. Providing adequate ventilation is essential because newborns are at a higher risk for respiratory issues, and the 3:1 ratio helps ensure that they receive enough breaths to support their respiratory function while also maintaining circulation through compressions.

Using this specific ratio helps to strike a balance between compressions, which maintain blood flow, and ventilations, which provide oxygenation. In contrast, the other options do not conform to the established protocols for newborn CPR, which can lead to ineffective resuscitation efforts.
