This is a great PEM induction video from the #EM3 team in the East Midlands (inc Damian Roland). Its got some great clips of clinical signs you will need to recognise in unwell children.
Some of the pattern recognition we learn in adult practice doesn't quite work as well in children. Using a structured approach if it isn't immediately apparent whats going on can help you pick your way around some of the common pitfalls. They suggest the nice traffic light system in this video.
