Narrative:

After 6 hours of normal uneventful flight, the aircraft encountered light to moderate turbulence at approximately 32W. Company procedures and training were followed and the appropriate actions were taken to insure the safety of passenger and crew. As the turbulence intensity increased, the appropriate announcements were made, a lower altitude was requested on HF through shanwick. The turbulence increased and several more requests for a lower altitude were made. At approximately 30W a clearance was received to descend from FL350 to FL340. A descent was initiated. At approximately FL345, the turbulence increased dramatically causing the autoplt and autothrottles to disengage. This turbulence lasted for a very short period of time. Upon leveling off at FL340 we were advised that there were injuries in cabin, including a flight attendant who appeared serious. The lead flight attendant requested medical attention from doctors on the flight. After consulting with crew and the doctors, a medical emergency was declared and the flight proceeded without further incident to amsterdam. EMS was standing by and all standard and company procedures were followed. Upon arrival at the gate, the station manager oversaw the treatment and transport of the injured flight attendant and passenger. The crew was assembled and deplaned the aircraft after all passenger and crew had been deplaned or released.
