PAX ILLNESS; FLC DECLARES EMER; DIVERTS.

Narrative

35 MI E OF SACRAMENTO; I WAS INFORMED BY THE FLT ATTENDANTS THAT A FEMALE PAX HAD STOPPED BREATHING AND THEY WERE PERFORMING CPR ON HER. I WAS 105 MI FROM RENO; SO I DECIDED TO DIVERT TO THE CLOSEST ARPT; SACRAMENTO. WE HAD AN UNEVENTFUL LNDG AND THE PARAMEDICS MET THE ACFT. THE LADY HAD BEEN REVIVED AND WAS TAKEN OFF THE ACFT BY GND PERSONNEL/PARAMEDICS. THE FLT ATTENDANTS TOLD ME THEY HAD USED A PARTIAL BOTTLE OF OXYGEN AND I TOLD THEM TO PUT IT IN THE OVERHEAD AND IT WOULD HAVE TO BE REPLACED AT A MAINT BASE LATER. I FAILED TO MAKE A LOGBOOK ENTRY OR INFORM DISPATCH THAT WE HAD USED AN OXYGEN BOTTLE. I WAS CONCERNED AT THE TIME WITH GETTING THE ACFT TO THE DEST AND ALSO DISTR WITH THE PAX INSISTING TO RETURN TO THE ACFT FOR THE FLT TO RENO. I HAD TOLD GND OPS THAT I WAS NOT GOING TO TAKE HER; BUT THERE WAS STILL A LOT OF ACTIVITY BTWN OPS; EMT'S AND MEDLINK DOCTORS. WE FINALLY PUSHED FROM THE GATE FOR RENO; I KNEW WE WERE LEGAL TO FLY WITH THE OXYGEN BOTTLE WE HAD ON BOARD; BUT DID NOT THINK ABOUT THE LOGBOOK ENTRY UNTIL I GOT TO MY HOTEL LATER. I INFORMED THE CHIEF PLT ON DUTY BY PHONE OF SIT; CALLED DISPATCH AND MAINT CTL AND THEY SAID THEY WOULD HAVE THE LOGBOOK ENTRY MADE AT THE NEXT STATION THE ACFT WENT THROUGH AND THE BOTTLE WOULD BE REPLACED LATER IN THE DAY.
