Use Entropy to titrate anesthetic drugs according to the individual needs of the patient Entropy measures the activity of the brain, which is the target organ for anesthetic medication, and has been shown to reflect the different phases of anesthesia. Furthermore, the use of Entropy has been found to reduce the use of certain hypnotic drugs. Therefore, Entropy may help you tailor the administration of anesthetic drugs for each patient individually.
There are two Entropy parameters: the fast-reacting Response Entropy (RE) and the more steady and robust State Entropy (SE). State Entropy consists of the entropy of the EEG signal calculated up to 32 Hz. Response Entropy includes additional high frequencies up to 47 Hz. Consequently the fast frontalis EMG (FEMG) signals enable a fast response time for RE.
