Oct 27, 2018 · Electroencephalographic density spectral array (DSA) monitoring has been proposed to facilitate the interpretation of unprocessed electroencephalogram (EEG) signals in patients undergoing general anaesthesia 1.

Dec 31, 2019 · Intraoperative awareness is a distressing complication of general anaesthesia associated with posttraumatic stress disorder. Bispectral index (BIS) values are generated from an empirically derived algorithm and are meant to reflect a …

Nov 6, 2023 · Monitoring the depth of anesthesia is a critical aspect of ensuring patient safety during medical procedures. The bispectral index (BIS) monitor is pivotal in this process. Maintaining BIS values within the range of 40 to 60 is essential to prevent anesthesia awareness and mitigate potential long-term psychological consequences.

The BIS™ monitor translates the raw EEG data into the easy-to-read BIS™ index. Both 2-channel and 4-channel monitors provide: User-configurable display; Versatile platform for future expandability; The 4-channel monitor provides: EEG monitoring; Asymmetry indicator (ASYM) Ability to trend BIS™-left and BIS™-right values

May 1, 2021 · In the decision curve analyses based on the n = 74 non-neurological sample, BIS = DSA was approximately equivalent to 3D-CAM in the 20–50% probability range, but as delirium probability exceeds 50% (e.g., 50–80% of ICU patients), BIS + DSA has nominally greater benefit.

SedLine offers the flexibility of choosing to display either an enhanced Multitaper Density Spectral Array (DSA) or a standard Hanning DSA. This provides the ability to see the symmetry of left and right sides of the brain.

Apr 11, 2022 · To our knowledge, the literature is scanty regarding DSA monitoring in remimazolam anesthesia. Subgroup analyses of these patients may also be performed to examine whether specific characteristics were associated …

Sep 16, 2004 · We report the management of a patient with status epilepticus who did not respond to intravenous phenytoin and benzodiazepines. We placed the BIS electrode on the patient's forehead and observed a high BIS number (94) during seizure activity with a typically epileptiform picture on the EEG trace.

One of them is the density spectral array (DSA), a colour display that represents the frequencies and amplitudes of brain waves through time, with the colour spectrum ranging from blue (minimum amplitude) to dark red (maximum amplitude).

Density spectral array (DSA) is a parameter obtained from bispectral index (BIS) VISTA Monitoring System Bilateral (BVMS) (Aspect Medical Systems INC, Norwood, MA).
