If a medical emergency played out before you, would you know what to do?
For most of us, it would be a call to 111 - but what about in the time it takes until help arrived?
Thankfully there are people like Jaide Neilson around.
The 17-year-old student was working a shift at Lady Jane's Ice Cream Parlour last week when a Japanese tourist was hit by a car outside her workplace.
Thanks to a first-aid course she completed while studying, the teenager knew just what to do and swung into action - putting her skills to the test in a real-life situation.
