If you are alone with the infant at the scene, do the following:

1. Tap the heel 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 (Figure 11d) while simultaneously checking for the infant’s brachial pulse for 5 but no more than 10 seconds (Figure 11e). If the infant does not respond and is not breathing (only gasping), yell for help.
4. If you cannot feel a pulse (or if you are unsure), begin CPR by doing 30 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. To perform CPR on an infant, do the following:
   • Be sure the infant is face-up on a hard surface.
   • Using two fingers, perform compressions in the center of the infant’s chest (Figure 11f); do not press on the end of the sternum as this can cause injury to the infant.
   • Compression depth should be about 1.5 inches (4 cm) and 100-120 compressions.
5. Perform CPR for about two minutes (using cycles of 30 compressions and two breaths). If help has not arrived, call 911/EMS and get an AED.
6. Use and follow AED prompts when available while continuing CPR until EMS arrives or until the infant’s condition normalizes.
