The sedation spectrum ranges from minimal sedation, moderate sedation, deep sedation, and general anaesthesia.
Minimal sedation is a minimally depressed level of consciousness in which the patient responds normally to tactile stimulation and verbal command. It is produced by a pharmacological method such as an oral sedative that you can take before a dental procedure.
Moderate sedation is an IV  drug-induced depression of consciousness during which patients respond purposefully to verbal commands, either alone or accompanied by light touch.
Deep sedation is an IV drug-induced depression of consciousness during which patients cannot be easily aroused.
General anaesthesia (GA) is an IV drug-induced loss of consciousness during which patients are not arousable, even by painful stimulation.
