EMS HELI EXPERIENCES POTENTIAL CONFLICT AT ZZZ WHILE TRYING TO TRANSIT AREA.

Narrative

I WAS THE PLT OF AN EMS HELI ENRTE FROM A SCENE CALL NW OF ZZZ AND UNDERNEATH THE APCH PATHS OF RWYS XXL&R (ZZZ). I WAS SWITCHED TO THE ZZZ FINAL CTLR FOR WY XXL&R AND HEARD MY CALLSIGN; X ACKNOWLEDGED. TFC WAS HVY AND THE CTLR WAS BUSY SO I COULDN'T GET A CALL IN BTWN HIS TFC CALLS AFTER MY INITIAL CALL. I STAYED AT 1300 FT MSL TO AVOID THE 1800 FT FLOOR OF THE CLASS B AIRSPACE AROUND ZZZ AND WAITED FOR THE FINAL CTLR TO CALL OUT TFC TO ME LIKE THEY NORMALLY DO. WE WORK WITH ATC AROUND ZZZ EVERY DAY. I SAW AN MD80 APCHING FROM THE L AND KEPT MY DISTANCE AND VERT SEPARATION (I ESTIMATE 1000 FT) FROM THE MD80. I NEVER SAW A REASON FOR THE MD80 TO WAVE-OFF; BUT LATER I WAS TOLD BY THE ATC SUPVR AT ZZZ THAT THE MD80 HAD WAVED OFF DUE TO A TCASII ALERT. THE CTLR FINALLY DID COME UP AND RECOMMEND A SWITCH TO TWR AND SAID SOMETHING GARBLED AND UNREADABLE ABOUT CLASS B AIRSPACE. I SWITCHED TO TWR; CALLED THE TFC I SAW APCHING RWY YY AND PROCEEDED TO THE HOSPITAL. HAD THE CTLR ASKED ME TO TURN E FOR TFC AVOIDANCE I WAS PREPARED TO ASK FOR A DIRECT RTE TO THE HOSPITAL BECAUSE OF THE CRITICAL NATURE OF THE PATIENT. IF I WERE FACED WITH THE SAME SIT AGAIN; I WOULD BREAK INTO THE CTLR'S TFC CALLS TO OTHER ACFT; ASK FOR A DIRECT PATH TO THE HOSPITAL; AND EXPLAIN THAT THE PATIENT ONBOARD WAS DYING. POSSIBLE SOLUTIONS FOR FUTURE INCIDENTS LIKE THIS INVOLVING EMS HELIS ARE TO MOVE BEYOND 'PRIORITY HANDLING' AND 'LIFEGUARD' PREFIXES TO CALL SIGNS; AND USE 'TRAUMA' OR 'CRITICAL PATIENT' PREFIXES WHEN THE PATIENT IS LITERALLY DYING AND EVERY MINUTE DELAYED FROM A HOSPITAL EMER ROOM IS CRITICAL TO THE PATIENT'S SURVIVAL. 3 CIRCUMSTANCES HAPPENED TO MEET AT THE SAME PLACE AND TIME -- AN MD80 ON FINAL APCH; A VERY BUSY ATC CTLR DURING A 'PUSH;' AND AN EMS HELI WITH A VERY CRITICAL PATIENT ON BOARD TRYING TO GET TO A TRAUMA CTR.
