I don't know what the context is, but it's probably referring to the doctor on duty at medical control. Some EMS systems allow the paramedic on scene to make the call for the helo at his/her discretion, other times they have to request it through medical control over the radio. If the doc at MEDCOM determines that it warrants a flight, the helo will be dispatched.
This keeps the helo from transporting Little Johnny for his broken arm when there is a critical trauma out in the boonies somewhere.
