DES MOINES, Iowa-  Officials at Des Moines hospitals tell WHO Radio News nearly all of the 76-students at the Iowa Law Enforcement Academy in Johnston, who were sickened by carbon monoxide exposure Thursday, were treated and released from local hospitals.  

Dr. Katrina Guest at Iowa Methodist Medical Center says their patients were given oxygen by face mask, and discharged.   She says had the cases been more serious, they could have undergone treatment in Hyperbaric chambers, but that was not necessary.

Mercy Medical Center Spokesman Gregg Lagan says most of their patients, at their main campus and at Mercy West were treated with oxygen and released.  He says three patients, however, required treatment in a Hyperbaric chamber.   It is not known if those patients were discharged as of Thursday night.

Patients were transported to local hospitals by ambulances, Iowa National Guard vehicles, and a DART bus.
