they help you know exactly how sedated someone is. you reach for a number between 40 and 60 iirc. 80 is waking up.
that's what the company claims. however... a classmate of mine is doing his project on bis. they are not terribly accurate, if you were doing a total tiva with propofol yeah its pretty accurate, other than that i wouldnt give it a whole lot of support.
just my humble opinion and experience in it's use. i strongly believe that if you titrate to a bis number mistakes will be made.
