An 11-year-old boy was "completely blue and unresponsive" when a nurse saw him by a Staten Island YMCA pool, so she told lifeguards, "I am a nurse, I know CPR," and was able to help revive him after two minutes. Pamela Glennon told the Advance, "His color came back immediately."

The boy was conscious and breathing on his own when paramedics arrived. The South Shore YMCA said, "A trained and certified YMCA lifeguard began emergency procedures immediately and YMCA staff contacted emergency services, who arrived on the scene quickly."

Glennon, who is a nurse-anesthetist at NYU Medical Center and Staten Island University Hospital said, "It’s nice to know that all the things you learn, you can execute them under pressure. I only did what any prudent nurse would have done."

You can learn CPR—which has new guidelines—by taking a class offered by the Red Cross.
