Routine monitors were attached, including electrocardiogram, non-invasive blood pressure, pulse oxymeter and BIS monitor
(BIS, Aspect Medical Systems, Newton, MA, USA), and baseline parameters such as heart rate (HR), systolic blood pressure, diastolic blood pressure, mean blood pressure and arterial oxygen saturation, were recorded.
The BIS monitor
was the first quantitative EEG device introduced into clinical practice to assess the depth of anesthesia.

At the same time BIS reading was taken using Aspect BIS monitor
Conventional EEG recording showed a pattern of burst suppression and raw EEG from BIS monitor
showed an isoelectric signal.
The interpretation of BIS monitor
values is relatively simple, with values ranging from zero to 100.
Bispectral index (BIS) has recently been developed to monitor depth of anesthesia, and the level of BIS was correlated with the level of hypnosis.[sup] Previous investigations have showed that BIS monitor
in ICU may help improve sedation and even during invasive events.[sup],,
Performance of linear model predicative controller (LMPC) is comparable to PID considering the time delay introduced by BIS monitor
during anesthesia control.
is a helpful device for adequate depth of anesthesia during operation.
Additionally the probe of BIS monitor
(Aspect Medical Systems) was adhered to the forehead and the values were recorded and the patient was given nasal O2 at a rate of 2 lt/min.
, which is a commercial device, integrates several disparate descriptors of the EEG into a single variable which is called BIS index.
These limitations of the BIS monitor
may be associated with the fact that its algorithm was developed based on EEG and clinical endpoints recorded in human patients and, consequently, may not be adapted to cats' EEG characteristics.
