I've already posted an entry on the St John Ambulance - First Aid. Don't leave it 'til you need it, Advertising and Community First Aid training campaign.
Since then I've seen the adverts and picked up a couple of leaflets. The adverts are hard hitting, although the use of the doll is not as distressing as if these had been real children.
If you want to know what you should do if you come across any of the situations shown then you can find out more at the web page First aid courses - don't leave it 'til you need it where you can find out about the correct treatment and find information about the courses St John Ambulance have available.
