Windsor Essex Doesn't Patch to Detroit Hospitals.The only time Michigan Units talk to Detroit Hospitals is when the patient is going to the Resuscitation Room in the ER. Life and Death, Right Now kind of stuff. Or if they need something special Decon or Security before entering the ER. Western Wayne and Down River Hospitals Require you call in everything. And trust me the reception is rather cool if you don't ( Make Reservations ) before you get there. When Windsor Essex takes a patient to Detroit the sending Doc gives a detailed report to the recieving Doc via telephone, before EMS is even notified. Windsor patients don't see the ER in Detroit unless something bad happens enroute. They are always direct admits to the Cath Lab, The Unit (ICU), Burn Unit, etc. Any Michigan patches can be monitored on either Detroit, Western Wayne, Downriver, or Washtenaw County Trunked systems All in the RR Database, Oakland County still on HEMS, I think, 155.340 or 155.400 open PL, and MED Channels 3, 4, 7, 8. Hope this helped.
