I monitor Waterbury/Cheshire Trinity EMS and Northwest CMED. While monitoring both, I hear calls such as "2-Alpha to Midstate," "Alpha to 19," etc. For example, a car called a few minutes ago "Alpha to 19," and now "upgraded" to "Delta to 19 with a respiratory distress on board." Are Alpha and Delta priority levels of response? Because I know Trinity generally just uses Priority 1 and Priority 2, but I could be missing something. If these are different levels of response, could anyone detail each level?
Thanks!
Thanks!
