What hand positioning technique should be used when providing CPR to an infant?

When performing CPR on an infant, the encircling thumbs technique is the recommended method because it effectively uses both hands to provide chest compressions while minimizing the risk of injury to the infant's fragile chest structure. This technique involves placing both thumbs on the infant's sternum and encircling their body with the fingers. By applying pressure with the thumbs, you can deliver compressions while using your fingers to stabilize the infant, ensuring proper depth and rate of compressions.

This method is advantageous because it allows for a more controlled and secure positioning, which is crucial given the smaller and softer anatomy of infants compared to older children or adults. It also enhances the responder's ability to monitor the infant's responsiveness and maintain an open airway during the procedure, which is vital for maintaining effective circulation during resuscitation efforts.
