Having done CPR / Defibrillation once it is traumatic and I did break a rib - he survived to make a full recovery and I had to apologise to him for the broken rib later (he was a member of our Church so not a random stranger). What made it less traumatic was knowing that he survived, it must be far worse if the person doesn’t make it. Whilst BA do have a duty to their crew and could have handed out a letter/sent a subsequent email to passengers this was not their fault and the attitude of the passenger is astounding.
