Mostly one shot but unless you can get a camera to go through glass without breaking it does get cuts. Note the comes and goes from the "old surgery room". I am sure if you look closer other scenes without people on them were bridge for other cuts but it does give you the ilusion of one single shot. If you are more patient than I you may time the "timer" on the wall and see if it matches the actual time gap. In summary, so much potential for a great end but the story very much dissapointed me.
