BA would require 48 hours noticed to provide Oxygen on a planned basis. Your friend used the supply on board that is for emergency use. (Which is was). When an airline knows that a passenger will be requiring oxygen they load the ac with a bottle(s) for their use and still have the emergency supplies in case the are required.
As fir the £100, anything medical related costs one hell of a lot due to a fair amount of paper work involved. Maybe if your friend has travel insurance it will pay out?
