Narrative:

While level at 24000 ft, the flight attendant advised me that a passenger required oxygen. She used her cabin portable oxygen bottle, but it failed to operate properly. I gave her the cockpit portable oxygen bottle. The flight attendant then advised me that it was working but not sufficient for her needs. I then declared an emergency, deployed the overhead oxygen masks and proceeded to fly direct to tlh airport. ATC was notified of the medical emergency and upon arrival the paramedics were waiting. The paramedics removed the ill passenger from the aircraft. Supplemental information from acn 260595: level at FL240, flight attendant advised a female passenger was having difficulty breathing and immediately administered oxygen. Passenger lost consciousness and we immediately declared emergency. Nothing can be done unless you question each passenger on medical history.
