Re: 517 and invasive procedures
Charlie,
That's the way I see it. The scope of the procedure and the risk to the patient determine if 517 applies. That is determined by the equipment used, the likely contingencies for the staff my face and, as I stated earlier, generally the altering of the patients, physical, psychological or conscious state of being. With a balloon in your arteries, you had better be careful about moving at all. Invasive is not a good rule of thumb- a simple blood stick is invasive but you can usually get up and leave if the technician keeps missing the vein.
I don't see partial compliance with 517 or any other section of the NEC for that matter; you are either all in or all out when it comes to patient safety. But, it does not hurt anything except the financial bottom line to comply with 517 in a doctors professional office. It is pointless however to provide emergency contingencies and justify the cost in a place where whatever treatment has started can be safely rescheduled for another day. That does not happen in a hospital- you are all the way in and better be ready if the lights in the building or the patient start to dim.
IMO 517 does not apply to a doctors office where the doctor examines the patient and PRESCRIBES treatment- general health concerns, weight loss, colds, setting broken bones (maybe), taking blood samples, etc. If the doctor does some sort of treatment that affects the patient while in the doctors care and makes the patient non-ambulatory (able to get around under their own power) then yes, it does fall under 517.
Maybe that is why doctors don't make house calls anymore- residences don't comply with 517?
