Emergency room Dr. Joan Dimopoulos was eating a chicken sandwich, when she began to choke.

"I couldn't breathe, and she recognized that I gave the universal choking sign. She had the courage to help me," Dr. Dimopoulos said.

Angel said she learned the Heimlich maneuver as a student at Proviso East High School.
