What is the main technique for CPR compressions on an infant?

The encircling thumbs technique is the recommended method for performing CPR compressions on an infant. This technique involves using both thumbs placed side by side on the breastbone, with the fingers encircling the infant's body to provide support and stabilization. The encircling thumbs allow for effective compressions while minimizing the risk of injury to the infant's fragile ribcage and organs.

This method is particularly useful because it enables the rescuer to maintain a secure grip on the infant, making it easier to perform compressions at the appropriate rate and depth. Compressing the chest with both thumbs also provides a more uniform pressure distribution over the breastbone, which can be more effective in generating blood flow during resuscitation efforts.

Other techniques, such as using one finger, may not provide sufficient depth or effectiveness in compressions for an infant. Squeezing the infant’s ribs could lead to injuries, as the ribs are not fully developed and are more prone to fracture. Additionally, compressions should not be performed on the stomach, as this can obstruct breathing and does not provide the necessary support for effective compressions. Thus, the encircling thumbs technique is the best practice for administering CPR to infants.
