I'm busy prepping for the boards, currently reviewing renal material, and I'm hoping that some of the dialysis/nephrology nurses out there can help me. I understand that air embolus can be a complication of hemodialysis. My problem is that I've never seen anyone undergo hemodialysis, so I don't really understand HOW the air gets in there. Sorry if this sounds like a silly question. I'll be grateful for any responses! Thanks!
