Most Medevacs are performed by the NJ State Police Aviation unit. Backups for that, and for inter-facility transport there are a few privately owned helicopters.

And we also deal with the US Coast Guard a lot with Water rescues, boater in distress, disabled vessels. When we do we usually deal with a MH-65 Doplhin or MH-60 Jayhawk.
We don't use MedEvacs often as we have a trauma center within our district. We will set up a secondary landing zone if the landing pad is out of service, there was a crash on the pad/disabled helicopter, or if multiple helicopters coming at once and cannot wait.
