How do I help hubby?

I'm due in March with our first baby. I've witnessed many live births, I know what happens, although I know it's not the same as experiencing it for yourself. But I know the process, I know what happens and I read a lot to help prepare. But hubby has never experienced a live birth and I just can't get it through his head that you don't even focus on the "gore" of it. He's fully committed to being there for me during labor and delivery. But I don't know to prepare him for what to expect. I'm scared to death he's going to legit pass out once everything starts progressing and it comes time to push and deliver. What do I do? Any advice or tips?
