Abstract
199 A 73-year-old woman was involved in a high-speed motor vehicle collision on a highway. When the ambulance arrived, the woman was found to be in pulseless electrical activity (PEA). Cardiopulmonary resuscitation was initiated and, although return of spontaneous circulation was initially achieved after 4 min, the patient went into PEA arrest three additional times until arrival to the emergency department. After an initial chest x-ray (Figure 1), a computed tomography (CT) scan of the chest revealed a large amount of air in the main pulmonary artery (Figures 2A and 2B, and Figure 3), with small amounts of air present in the right atrium, right ventricle, left and right brachiocephalic trunks (Figure 4), proximal superior vena cava and left subclavian vein. A left first rib fracture, bilateral pneumothoraces and left subclavian vein hematoma were present; trauma to the left subclavian vein was believed to be the source of the air embolism. Although hyperbaric oxygen and aspiration of the air under right heart catheterization were considered, the patient stabilized with mechanical ventilation and vasopressors. A CT scan of the chest 6 h later showed virtually complete resolution of the air in the vessels and heart, and the patient was discharged from hospital two months later.

How this classification was reachedexpand
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.
