Effective October 12th, 2004 a revised MAP will take effect. Changes developed with the input of numerous providers, administrators, physicians, and aeromedical experts were outlined in a letter mailed to all corps (click here for a copy of the letter) by County EMS Coordinator Mike McEvoy. A quick overview of changes is available in a document accompanying McEvoy’s letter (click here for a highlighted copy of changes). The October 2004 revision of the MA Manual incorporates all changes made since the prior (January 2003) printing. The entire Mutual Aid Manual can be downloaded by clicking here or using the downloads button at the top of this page.
