Using Heart Rate Variability Monitoring for Dexmedetomidine Dosing in Neurointensive Care Patients

Dexmedetomidine in the neurointensive care unit.

Dexmedetomidine is a new alpha-2 agonist with high specificity to alpha-2 receptors. The aim of this review is to present the most recent topics regarding the advantages in using dexmedetomidine in clinical anesthesia and intensive care, while discussing the controversial issue of its harmful effect on cerebral blood flow.

Ovid: Electrophysiologic monitoring in neurointensive care

Cumulative evidence of potential benefits of electroencephalography (EEG) and evoked potentials in the management of patients with acute cerebral damage has been confirmed. Continuous EEG monitoring is the best method for detecting nonconvulsive seizures and is strongly recommended for the treatment of status epilepticus. Continuously displayed, validated quantitative EEG may facilitate early d...

A Novel Fuzzy Based Method for Heart Rate Variability Prediction

Abstract In this paper, a novel technique based on fuzzy method is presented for chaotic nonlinear time series prediction. Fuzzy approach with the gradient learning algorithm and methods constitutes the main components of this method. This learning process in this method is similar to conventional gradient descent learning process, except that the input patterns and parameters are stored in mem...

Digital Heart Rate Variability Monitoring System

In this paper we describe the implementation of an application specific integrated chip (ASIC) for digital heart rate variability monitoring system. The proposed system extracts the R peaks from the input ECG signals using peak detection algorithm and stores the computed R-R intervals into an efficient SRAM as the internal memory. A histogram sorter sorts the R-R intervals which are then indexe...
