Why no splints or readily adaptable splint material (apparently)?

I'll bet I have treated at least thirty times as many fractures or potential fractures as CPR situations (one without any kind of face shield or protection whatever). Granted, splints can usually be improvised, but I always like to have at least one or two ready to apply - saved time and they were more comfortable and effective.

Lots of ways to break bones and fractures are commonly encountered in many different situations.
