WebMethods: In this work, an event-based model predictive control system is proposed and analyzed. The nonlinear patient model is used to form the predictor structure and its linear part is exploited to design the predictive controller, resulting in an individualized approach. In such a scenario, the BIS is the controlled variable and the propofol ... WebBackground: The bispectral index (BIS) monitor is a quantitative electroencephalographic (EEG) device that is widely used to assess the hypnotic component of anaesthesia, especially when neuromuscular blocking drugs are used. It has been shown that the BIS is sensitive to changes in electromyogram (EMG) activity in anaesthetized patients. A …

WebBIS™ Monitoring — Reliable, Proven. Studies show an 80% reduction in awareness has been demonstrated when using BIS™ monitoring compared to routine care in both … Bispectral index (BIS) is one of several technologies used to monitor depth of anesthesia. BIS monitors are used to supplement Guedel's classification system for determining depth of anesthesia. Titrating anesthetic agents to a specific bispectral index during general anesthesia in adults (and children over 1 … See more The BIS was introduced by Aspect Medical Systems, Inc. in 1994 as a novel measure of the level of consciousness by algorithmic analysis of a patient's electroencephalogram during general anesthesia. … See more BIS monitoring is widely used in operating rooms and ICUs, as well as in emergency departments. Some of the benefits that have been attributed to it include: • Reduced time to extubation and discharge from the operating room and PACU See more • Anaesthetic machine • Entropy monitoring • Evoked potentials • Respiratory monitoring • Spectral edge frequency See more The bispectral index is a statistically based, empirically derived complex parameter. It is a weighted sum of several electroencephalographic subparameters, including a See more Some of the limitations of this form of processed EEG monitoring are: • Unreliability with certain drugs, such as ketamine, nitrous oxide and ephedrine. Ketamine may … See more The BIS is an electroencephalogram-derived multivariant scale that, when a drug such a propofol is used, correlates with the metabolic … See more • Grover VK, Bharti N (2008).
