Abstract

fetched live from OpenAlex

This paper proposes a constrained control scheme for the control of the depth of hypnosis in clinical anesthesia. The proposed scheme guarantees overdosing prevention while taking into account infusion rate limits and safety constraints on the plasma concentration. The core idea is to formulate anesthesia as a constrained control problem and design a closed-form control scheme based on the explicit reference governor philosophy. More precisely, the proposed architecture consists of a stabilizing control loop and of an add-on control unit that is able to ensure the constraints satisfaction at all times. In this paper, this architecture has been implemented within the iControl system, a platform for clinical evaluation of control schemes. The proposed scheme is evaluated on a simulated surgical procedure for 44 patients. The results demonstrate that the proposed scheme can deliver propofol to yield induction time of (mean) 6.24 [min], while satisfying the imposed safety constraints.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
