Staffers revive Columbia Falls High School student who collapsed in gym class
KALISPELL, Mont. — Columbia Falls High School staffers used CPR and an automated external defibrillator to restore the heartbeat of a 16-year-old student who collapsed during gym class.
The Daily Inter Lake reports (http://bit.ly/wNCj7v) health and physical education teacher Troy Bowman and school nurse Cathy Dragonfly aided the boy Wednesday morning. He was then taken to Kalispell Regional Medical Center, where he was listed in stable condition in the intensive care unit later Wednesday.
Superintendent Michael Nicosia says it is unclear what caused the student to collapse.
[Blogger's note: If the AED restored his heartbeat, the cause of his collapse was most likely Sudden Cardiac Arrest.]
