Deep sedation/general anesthesia - first 15 minutes

anesthesia time begins when the doctor administering the anesthetic agent initiates the appropriate anesthesia and non-invasive monitoring protocol and remains in continuous attendance of the patient. anesthesia services are considered completed when the patient may be safely left under the observation of trained personnel and the doctor may safely leave the room to attend to other patients or duties. the level of anesthesia is determined by the anesthesia provider's documentation of the anesthetic effects upon the central nervous system and not dependent upon the route of administration.
