the 400 comes from because they say on avarage a person will give 60-65ish compressions a min if done correctly. that means if you devide your 400 by 60-65ish you roughly get 6 mins of compressions which is as i said above is the rough amount of oxygen in your body. after this time no oxygen = dead
they bank on the fact they can get an emergancy response to the casualty within the 6 mins so they can take over and perform the CPR with oxygen/breaths correctly and get them breathing again.
i dont think this is taught anywhere in the uk.
