What technique is recommended for two-rescuer CPR on an infant?

The two-thumb encircling hands technique is the recommended approach for performing CPR on an infant when there are two rescuers available. This method provides effective compressions by allowing the rescuer to use their thumbs to compress the chest while the fingers encircle the infant’s torso, stabilizing the infant and ensuring a better seal for rescue breaths if needed.

Using this technique allows for a more uniform distribution of pressure across the chest and minimizes the risk of injury, which is crucial for an infant's delicate body. The positioning makes it easier to provide higher-quality compressions, adhering to the recommended guidelines for depth and rate.

In comparison, the other methods are less effective or not advisable for infant CPR in a two-rescuer scenario. For instance, the two-finger technique, while sometimes used for single rescuer situations, does not provide the same level of stability and efficiency as the encircling hands technique. The single thumb technique and one-handed technique are not appropriate for infants as they do not offer adequate support or effective compression dynamics needed for this age group. Thus, using the two-thumb encircling hands technique is both the safest and the most effective method when two trained rescuers are present.
