Being a Paramedic I've responded to the local Airport more than once(GRB). We drive in at a special gate, then are escorted to the plane and go on board to start treatment. I've been retired for 2 1/2 years but never had anybody slow our arrival to the Pt. I've also been onboard a flight this last Memorial day when a person had a syncapol episode. I did go and help. The Doctor couldn't work the Chem Bg,(blood gluclose machine) and finally just went back to his seat. The flight attendent said the Pilot was asking if we needed to divert. I made the decission not to and gave him the pt.'s vitals and that she was improving. No complaints except she had been up for over 24 hrs, hadn't eaten but did have a drink onboard. Chem Bg was normal and she had no medical Hx. Paramedics are used to working in the mud, having the Pd hold a flashlight so we could see the veins to start a Iv. We are the MD, Respitory Therapist and nurse when all hell is breaking loose outside of the Hospital.
Yes some large airports do have EMT's and Paramedics on duty, but they usually have other duties too. But if they don't have them they call 911 and know exactly when we arrive and who was sent by 911. Here it could be Green Bay, Ashwaubenon, or Depere so it would be very unlikely someone just showing up and being in the right Rescue Squad. We also do yearly exercises with the Airport to coordinate responses and work out any problems before they can happen.
