Nurses save lives on Southwest flight and at work.

Baltimore couple Emily Raines and Daniel Shifflett, both with medical experience, teamed up to save the life of a man whose heart stopped beating on a Southwest flight home from a Caribbean cruise. They performed CPR for 20 minutes and managed to resuscitate him seven minutes before landing. The ill passenger's wife later thanked them and promised to send them home-baked cookies. Raines credited her employer's CPR training program for the successful resuscitation and said the experience deepened her and Shifflett's bond.
