Hi,
I'm not that familiar with the administering of anesthesia but my first concern isn't fraud, it is the well being of the person that is sedated but not being monitored. What if something goes wrong and nobody is in the room?
Putting those thoughts aside and using strictly my technical side, technically the patient is under anesthesia so even if he is not in the room, the patient is under anesthesia. However, even as I'm typing that I'm thinking "BUT WHAT IF SOMETHING GOES WRONG WITH THE PATIENT THAT WAS LEFT ALONE, EVEN FOR ONLY 10 MINUTES". Sorry, maybe that happens in the real world, but I like my personally little happy bubble, where a patient wouldn't be left alone while under anesthesia.
Maybe another forum member has some experience with this as well and can shed some light on this!
