Which technique is preferred for single-provider infant CPR?

The encircling thumbs technique is preferred for single-provider infant CPR because it allows for effective chest compressions while simultaneously providing rescue breaths. In this technique, the rescuer uses both thumbs to compress the infant's chest while the fingers encircle the back to provide support and maintain proper positioning. This method is particularly beneficial for infants because it allows for improved stability and control during compressions, reducing the risk of injury. Additionally, this technique ensures that the rescuer can seamlessly transition from compressions to breaths without having to reposition or readjust their hands significantly, which can save critical time during emergency situations.

The other methods, such as the two-finger technique or one-hand technique, may not provide the same level of effectiveness or stability while performing CPR on an infant. Therefore, the encircling thumbs technique is the most suitable for single-provider infant CPR.
