Nice thought Tom, to thank the member of staff; doing 'bystander' CPR, is so far out of peoples 'comfort zone' it's bound to leave them a bit shaken, I say 'bystander' because from what you tell us about most care homes, being a care worker doesn't always mean you staff are ready willing or able to to do it. I suppose this is a situation where there is no easy, clear cut answer, and with the clock ticking, no time for debate or deliberation. All rather sad really
