Fiona Winster: If you count aloud as you do the compressions, it'll help you get the right speed. So you just count one-and-two-and-three. Once you've done fifteen of those, you go straight back to the head and you do two more breaths, just as before. And you just keep repeating then, in cycles of two breaths, fifteen compressions, until medical help arrives. Now in those situations, the chances of success will decrease quite rapidly, but that's not to say that no one will survive. It's just to say that not that many will. But at least you know, if you were the person who tried resuscitation, that you gave them their very best possible chance.
