2. Fig 1
The raw data used for the Pk calculations with the BIS (a), CSI (b), and IoC (c) and the OAAS scale levels 5 (awake), and 1–0 (anaesthetized). The triangles represent the indices while awake and after the induction and the circles represent the indices recorded during the maintenance of anaesthesia.

(a) An example of a recording where there was a decrease in the three indices after administration of atracurium, the effect was pronounced most clearly on the CSI; (b) an example of a recording where a good agreement was achieved among the three indices.

(a) From the surface EEG are extracted three parameters, that is, the beta-ratio, the symbolic dynamics, and the ESR. (b) Method used to calculate the IoC. SD, symbolic dynamics; Beta, beta-ratio; ESR, EEG suppression rate.

The IoC-view monitor with a display showing the EEG and in the upper right corner, the IoC. Additionally, the value for ESR and bars for the EMG activity and the quality of the signal (SQI) are shown.
