WebDuring surgery under general anesthesia, the patient expects to be unconscious and to not experience pain. 10 Both inhaled and intravenous agents are commonly employed to achieve that goal. When inhaled agents are used, end-expired anesthetic agent monitoring can insure that the inhaled anesthetic agent and appropriate dose are being delivered. WebA BIS value between 40 and 60 indicates an appropriate level for general anaesthesia, as recommended by the manufacturer. The BIS monitor thus gives the anaesthetist an indication of how "deep" under anaesthesia …
