The standard BA Alert Call, i.e. the call the pilots make to alert the crew that there is an issue that may modify onboard service and require (possibly) some cabin crew action is "Will the Senior Cabin Crew Member report to the Flight Deck immediately." This is not a panicked call but a well practised one made in the sim numerous times by all pilots. The immediate response from CC is for the SCCM and nearest other crew member to go into the FD, often they will take a portable O2 with them in case it is an incapacitation issue. Seems like everyone did as they were trained to do and no great drama unfolded.. A potentially difficult situation well dealt with by all crew
