AN ILL PAX RESULTED IN AN F100 FLT CREW DECLARING AN INFLT EMER.

Narrative

WE WERE ON THE BYP ARR ABOUT 50 MI S OF TUL WHEN THE #2 FLT ATTENDANT CALLED AND SAID THAT WE HAD A PAX THAT HAD BECOME VERY SICK AND HE NEEDED MEDICAL TREATMENT. I ASKED THE FLT ATTENDANT TO CALL ME BACK WITH MORE DETAILS. AT THAT POINT; THE FO AND I LOOKED FOR THE CLOSEST ARPT AND SENT A MESSAGE TO DISPATCH THAT WE HAD A MEDICAL EMER. A FEW MINS LATER; THE #2 FLT ATTENDANT CALLED BACK AND SAID THAT THE PAX WAS THROWING UP PANCREATIC JUICES AND POSSIBLE BLOOD AND THE PAX HAD A HISTORY OF PANCREAS PROBS. AT THIS POINT; WE STARTED TO LOOK AT LNDG AT TUL; BUT BY THIS TIME BY GOING DIRECT TO DFW; WE WERE ABOUT HALF-WAY BTWN THE TWO. WE DECLARED AN INFLT EMER WITH ZFW. THE FLT ATTENDANT CALLED BACK AND SAID WE HAD AN EMER ROOM REGISTERED NURSE ON BOARD. THE REGISTERED NURSE LOOKED AT; AND WORKED ON; THE PAX AND THE PAX WAS NOT THROWING UP BLOOD AND THINGS WERE UNDER CTL; BUT WE NEEDED TO LAND VERY SOON BECAUSE THE PAX WAS VERY ILL. WITH THIS INFO FROM THE REGISTERED NURSE AND THE FLT ATTENDANTS I DECIDED TO GO DFW. WE LANDED AT DFW IN ABOUT 18 MINS. DFW MEDICAL EMER PERSONNEL MET THE ACFT AT THE GATE; TREATED THE SICK PAX ON THE ACFT; AND THEN TOOK THE SICK PAX AWAY.
