“Regardless of the administration method, because sedation and general anesthesia are a continuum, it is not always possible to predict how an individual patient will respond. Hence, practitioners intending to produce a given level of sedation should be able to diagnose and manage the physiologic consequences (rescue) for patients whose level of sedation becomes deeper than initially intended.​​​ Sedation & General Anesthesia safety is directly related to the degree of vigilance, skill and knowledge of the doctor providing it."​
