I shouldn't worry too much about driving yourself to hosp in your own amb - what about this: You'll know what I mean by the FRU desk in Control (the desk that runs the fast response cars, for the non-LAS types). About three years ago I did a few stints on the desk, and we were called to a collapse on a bus in Hounslow. A car was sent but - due to pressure of work - no ambulnce was available. After about twenty minutes on scene the FRU pilot called up to ask if an ambulance was likely in the next five minutes. The sector desk said "Sorry - No". Next thing I know is the radio priority buton going off. I answered it and the FRU pilot put in a "Blue Call" (Priority call) to the local hospital. It went something like this: "I'm blue to [hospital] with an adult male, collapsed on a bus query cause, GCS 9, Pulse 120, etc etc etc - Oh, by the way, we are en route on the bus he collapsed on - I'm directing the driver to the hospital. Yes - the girl on the car had commandeered the bus, to "blue" the patient into hospital. When I passed the call to the casualty sister, the reaction was "The patient is being blued in on a bus??? - Oh OK - what Number bus???"
