I have had some lessons, and would give it a very good attempt, if needed
and no one else was able to help.
I should get more lessons, it is one of those things in life, we all need to know and do.
I think you can have a look on You tube, at least get some idea. :)
I was a first aider many years ago and the training has stuck with me. I think it's an important skill (that could save lives) and I think everyone should have some first aid knowledge. My husband took a first aid course when we first became parents as he had literally no knowledge of how to do any first aid.
I also have the Australian Red Cross App on my phone which can provide basic training to you, and also a point of reference in the event of you being first on scene to administer first aid. I'm a huge fan of this free app and I've encouraged my friends to download the app too. - http://parent101.com.au/product-review-first-aid-app-by-the-australian-red-cross/
