If you are not alone with the infant at the scene, do the following:

1. Tap the bottom of their foot and talk loudly at the infant to determine if they are responsive.
2. If the infant does not respond, have the second rescuer call 911/EMS, and get an AED. (The ILCOR emphasizes that cell phones are available everywhere now and most have a built-in speakerphone, so you can call while at the scene.)
3. Assess if they are breathing. Feel for the infant’s brachial pulse for 5 but no more than 10 seconds.
4. If you cannot feel a pulse (or if you are unsure), begin CPR by doing 15 compressions followed by two breaths. If you can feel a pulse but the rate is less than 60 beats per minute, begin CPR. This rate is too slow for an infant.
5. When the second rescuer returns, begin CPR by performing 15 compressions by one rescuer and two breaths by the second rescuer. If the second rescuer can fit their hands around the infant’s chest, perform CPR using the two thumb-encircling hands method (Figure 11g). Do not press on the bottom end of the sternum as this can cause injury to the infant.
6. Compressions should be approximately 1.5 inches (4 cm) deep and at a rate of at least 100-120 per minute.
7. Use and follow AED prompts when available while continuing CPR until EMS arrives or until the infant’s condition normalizes.
