I like Eric's stuff. His vent book is a solid source for most prehospital clinicians, IMO. His podcasts are generally decent as well, and got a thumbs up rating from me.
I'd gladly refer his podcasts to any, and all who are interested. He is very much into staying ahead of, and/ or into "cutting edge" stuff, but generally gives the standard "follow your protocols" waiver.
I did the ACE-Prep course online and a couple others. I like to study, so I study a lot.. While working towards my FP-C and CCP-C I was working in a CCT role and also already taken all the AP/ Biology classes in college which was a huge help...I was averaging 10-15 hours of studying a week.
