Welcome

This is a topic overview and personal opinion. Not a detailed discussion of all the pros and cons. Not a demonstration of technique. Not an assessment of competence and certainly not medical advice.

The management is described in increasing order of difficulty, from something a bystander may be able to do without specialised equipment, to more complex management that does need specialised equipment and monitoring.

All of this discussion assumes that ur casualty has one injury only. But chances are they they'll have more, for which you need a deeper understanding of how to deal with that.
