Entropy Module, E-ENTROPY

1 GE HealthcareEntropy module , E-ENTROPYA key measurement to personalized anesthesiaE- Entropy is a single-width plug-in module with the unique Entropy algorithm, designed for monitoring the state of the central nervous system during anesthesiaBenefits of Entropy measurementUsing Entropy may enable the clinician to: Ensure faster and more predictable wake-up and extubation Improve drug management Avoid unnecessarily deep anesthesia and decrease side effects Prevent unexpected recoveryMeasurement technology Utilizes the intuitive and published Entropy algorithm, a Datex-Ohmeda innovation reference: Vierti -Oja et al, Acta Anesthesiol Scand 2004; 48: 154-161 Based on acquisition and processing of EEG and FEMG signals Features two Entropy parametersResponse Entropy (RE) - a fast reacting parameter for detecting activation of facial musclesState Entropy (SE) - a steady and robust parameter for assessing the hypnotic effect of anesthetic drugs in the brainDisplay Options Entropy information integrated into Datex-Ohmeda modular anesthesia monitor screens Digital display and trending of the Entropy parameters and Burst Suppression Ratio (BSR) Entropy EEG waveform display, one 16:00 16:00:05 Technical DataDirect function keysEntropy Opens Entropy menuCheck Sensor Starts impedance measurement of sensor electrodesDimensions and weightModule size (WxDxH) 37 x 186 x 112 x x inModule weight lbEntropy Measurement method Entropy monitoring is based on acquisition and processing of raw EEG and FEMG signals using the Entropy algorithm.

2 The signal is measured by placing a dispos-able sensor on patient s forehead. Entropy parameters, RE and SE, may help the anesthesiologist to assess the effect of certain anesthetics on the patient s central nervous 10000 Input dynamic range 500 VInput offset 300 mVFrequency range - 118 HzNoise level < V @ - 118 HzInput impedance 1 M @ 50 HzCMRR >100 dBDefibrillation protection 3000 V, 130 JA/D conversionSampling frequency 1600 HzResolution 60 nVWaveform display (One channel of raw EEG)Range 800 VppScales 25/50/100/250/400 VSweep speed mm/sNumeric display (RE, SE and BSR)Range RE 0-100SE 0-91 BSR 0-100 %Accuracy 1 or 1 %Display resolution 1 digitDisplay update 1 16:00 16:00.
