Optimization Design of EEG Bispectral Index Monitor for Nursing of Neurocritical Patients
In order to achieve dynamic monitoring of neurological critical patients using the current BIS monitor,an improved in-ternal anesthesia monitoring architecture was studied,and an optimized BIS monitor was proposed and its effectiveness was verified.The results indicate that the framework proposed in the study has higher accuracy in anesthesia monitoring,with an overall improve-ment of about 0.74％,and has the highest predictive accuracy and stability.In practical application,the difference of arterial blood pressure before and after anesthesia is 6％～14％,while the change of body temperature is maintained between 0.9 ℃～1.6 ℃,the change of heart rate after surgery is also maintained between 1.3～4.4 times/min,the difference of oxygen saturation is only 0.4％～0.5％,and the difference of BIS index score is between 5～12 points.At the same time,its accuracy in anesthesia induction,mainte-nance,and awakening was 58.1％,96.0％,and 56.6％,respectively,with an overall accuracy of 90.1％and the best overall per-formance.Overall,the improved BIS monitor proposed in the study has high effectiveness in monitoring anesthesia depth and is of great significance for the care of critically ill patients with neurological disorders.
