Abstract
Objective: The purpose of the research reported in this paper was to investigate, using data gathered from simulated Out of Hospital Cardiac Arrest (OHCA) exercises, the impact on the quality of chest compressions when introducing a King Laryngeal-Tube (KLT) airway and then employing the LUCAS mechanical CPR device or employing the LUCAS and then securing the KLT airway. These findings may also provide EMS practitioners with evidence-based guidance on how to better employ the LUCAS in an OHCA. Methods: Student paramedic 2-person crews were assigned a simulated call for a "58 y/o patient, not conscious, not-breathing". On entering the scene, the crew finds an adult manikin supine, on the floor. The crew managed the initial stages of a simulated adult OHCA VF simulation using a simple, well-practiced BLS drill, a LUCAS, and a Supra-Glottic-Airway (SGA) while minimising interruptions to chest compressions. Results: The primary outcome measure was the length of time that no chest compressions were taking place in each simulated scenario. A significant statistical difference was found between the LUCAS-first condition, with a mean time off the chest of 4.63 s and the Airway-first condition, which had 5.25 s, z (-8.509) with critical value 1.96.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
