Answer: After giving one minute of rescue breathing
Step-by-step explanation:
If you're alone with a child or baby who is unresponsive and not breathing (or only gasping), call 911 after you've done 2 minutes of cardiopulmonary resuscitation (CPR). If someone else is present, shout for the person to call 911 and then have them locate an AED (a defibrillator) right away while you begin CPR.
