The point is, if everyone "involved" in a medical emergency was to call an ambulance, then you'd have the ambulance fleet of 6 counties in attendance.
The simple fact of the matter is that after exactly such an instance, ATC's responsibility has been redefined as simply to handle the traffic as expeditiously as possible. Your handling agent is there for all other arrangements.
Thankyou Nemo for interpreting my response quite correctly.
