BEND, OR -- After 20 years of service as bend fire Chief, Larry Langston will retire at the end of the day today. Langston says a big improvement he’s been a part of is the improvement of pre-hospital care. Instead of trying to race to get car wreck or heart attack victims to the emergency room, now there is an emphasis on  pre-hospital care. That care includes  sophisticated, well quipped ambulances that can stabilize patients. Langston says in Bend more than 50-per cent of patients in full cardiac arrest now survive and walk out of the hospital.
