Anesthesia is the administration of a drug or other anesthetic agent by injection injection or inhalationinhalation to obtain muscular muscular relaxation, loss of sensation and/or relaxation, loss of sensation and/or loss of consciousness.loss of consciousness.
Anesthesia is classified according to the effect they have on the body.

Time Units Time UnitsTime Units will be determined by using the total time in minutes actually spent performing the procedure.
Fifteen MinutesFifteen Minutes is equivalent to one (1) time unit.
Time UnitsTime Units will be rounded to the tenth. Therefore, if the procedure lasted 49 minutes, the time units in this example would be 3.26 or 3.3 time units. (i.e., 49/15=3.26 (i.e., 49/15=3.26 or 3.3)or 3.3)
