I was quite young when I first saw CPR being performed on an old lady who had a heart attack at church. A Nurse did CPR for a few minutes and the lady was concious by the time the ambulance arrived!! (1980's - before AEDs etc on ambulances) It was years later after fellow St John colleagues failed to save someone that I realised that CPR doesn't always work so impresively! Babies, spent many a time with young nephew tipped up with back blows because eyes bigger than mouth!! The first time it happened it was scarey but I just automatically did the first aid without thinking about it.
