<p>i've been in a surgery before (neurological, shadowing), and the anesth. explained to me what all the equipment was for. the machinery is very complex, and they have to know every single detail about it. they also have to control oxygen, and nitrogen levels, while keeping an eye on hb levels and such. they really have to beable to multi task. also, IMO, the surgeon is really just a human hacker, however, it is the anesth that really keeps the patient alive.</p>
