As Hurricane Isaac dumped rain on the city, by noon Wednesday, New Orleans' EMS system had received 156 calls for service, and city officials were working to triage patients with special medical needs who were calling for help. Ambulances were responding to 9-1-1 calls but could not reach every area of the city.
The special medical needs shelter at the LSU Field House in Baton Rouge, meanwhile, reached capacity for people who rely on electric-powered health equipment. They were being directed to a special shelter in Alexandria.
