This is coming from a canadian point of view, so I don't know exactly what the American level of training is like for BLS providers, but I disagree with almost everything written in this post.
I find that pulse oximetery is a very useful tool, and can significantly alter the course of treatment. I assume your BLS providers are allowed to give oxygen? If so, the pulse oximeter (along with proper pt assessment) can give an indication of what type of oxygen therapy the pt. needs and also how well present oxygen therapy is working.
As far as BGL's and Monitors go, the BLS provider may not be able to do anything about it, but I believe that there is no harm in having good dianostic tools at their disposal, as it will help to speed the treatment process along when the patient does come into contact with ALS care.
