What should you do with your fingers when using the encircling thumbs technique?

The encircling thumbs technique is specifically designed for delivering effective chest compressions to an infant during CPR. When using this technique, your fingers should circle around the back of the infant, providing a secure grip while your thumbs perform the compressions on the sternum. This positioning allows for better stabilization of the infant while you can apply adequate pressure through your thumbs.

Holding the infant's arms is not part of the technique, as it's important to keep the infant stable without restricting movement that may help during the resuscitation process. Pressing down on the stomach is not suitable since the focus is on the chest, and pressing the stomach could lead to ineffective compressions or even cause harm. Placing fingers underneath the ribs does not provide the necessary support for effective chest compressions and could also result in injury.

Understanding the purpose of the encircling thumbs technique is crucial for effective infant CPR, as it maximizes the effectiveness of the compressions while maintaining the safety and stability of the infant.
