We all realise the importance of being able to cope with minor cuts and injuries at home. Most parents will have had the experience of one of their kids falling and grazing knees or elbows. Similarly, few of us will have made it to adulthood without a minor cut that produces bleeding.

Whilst we go about the usual tasks in our day few of us will spend any time on the thought of what we might do or be able to do should an immediate medical emergency arise.
