A man traveling from Sacramento to Burbank had a health crisis on the right flight.
Thirty-five hospital workers were headed to a union bargaining session on the Southwest Airlines flight Tuesday when they heard someone shouting "code blue" from the back of the plane.
In hospitals, a "code blue" indicates someone's heart has stopped.
Respiratory therapist Erin O'Neil says he "immediately clicked into work mode."
O'Neil and registered nurse David Lei used a device that administers mouth-to-mouth resuscitation provided by a flight attendant and revived the man.
The workers said the man, whose identity was not immediately available, was able to walk off the plane to meet waiting paramedics.
