Tom, Your comment about the need for CFR's in London (I am a rural CFR by the way) ignores the fact that the concept of CFR's was originally started in downtown Seattle USA where, I am told, the scheme dramatically reduced deaths from heart attacks. From experience the fact that anyone has turned up with skill and authority gives a great deal of comfort and relief to patients and loved-ones alike. I got the book from my RGN wife (who refuses to do CFR, I wonder why!)at Christmas - great read, thanks.
