CONCORD -- A school nurse's quick thinking on Monday saved a student who had passed out and wasn't breathing at a Concord elementary school on Monday, authorities said.

The nurse performed CPR after the student passed out about 10 a.m. at Highlands Elementary School, according to a dispatcher from Contra Costa Fire Protection District and confirmed by Mt. Diablo Unified School District Superintendent Dr. Nellie Meyer.

"We are grateful for the nurse's quick response," Meyer said.

Details of the incident were not available immediately, but a dispatcher said emergency crews were sent after reports that a child at the school was unconscious and not breathing. The student was breathing by the time emergency crews arrived and was taken via ambulance to a hospital.

Authorities did not say which grade the student attends or whether the student was a boy or girl.
