anaesthesiologist here.. agree that this machine is probably safe for giving sedation. colonoscopies inhabit a grey area where you can do them with benzodiazepine sedation but they are better with propofol, the only issue being with propofol is you have to be on the ball to titrate the infusion as things progress. A machine is quite capable of doing this. for surgery requiring full general anaesthesia you do need someone immediately on hand (doctor or nurse-anaesthetist) who is an airway specialist because if you lose your airway you generally don't have long to re-establish it before the patient dies.
