Abstract
OBJECTIVES: To determine the prevalence of and risk factors for cardiac arrest during intubation in ICU, as well as the association of ICU intubation-related cardiac arrest with 28-day mortality. DESIGN: Retrospective analysis of prospectively collected data. SETTING: Sixty-four French ICUs. PATIENTS: Critically ill patients requiring intubation in the ICU. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: During the 1,847 intubation procedures included, 49 cardiac arrests (2.7%) occurred, including 14 without return of spontaneous circulation (28.6%) and 35 with return of spontaneous circulation (71.4%). In multivariate analysis, the main predictors of intubation-related cardiac arrest were arterial hypotension (systolic blood pressure < 90 mm Hg) prior to intubation (odds ratio = 3.406 [1.797-6.454]; p = 0.0002), hypoxemia prior to intubation (odds ratio = 3.991 [2.101-7.583]; p < 0.0001), absence of preoxygenation (odds ratio = 3.584 [1.287-9.985]; p = 0.0146), overweight/obesity (body mass index > 25 kg/m; odds ratio = 2.005 [1.017-3.951]; p = 0.0445), and age more than 75 years old (odds ratio = 2.251 [1.080-4.678]; p = 0.0297). Overall 28-day mortality rate was 31.2% (577/1,847) and was significantly higher in patients who experienced intubation-related cardiac arrest than in noncardiac arrest patients (73.5% vs 30.1%; p < 0.001). After multivariate analysis, intubation-related cardiac arrest was an independent risk factor for 28-day mortality (hazard ratio = 3.9 [2.4-6.3]; p < 0.0001). CONCLUSIONS: ICU intubation-related cardiac arrest occurs in one of 40 procedures with high immediate and 28-day mortality. We identified five independent risk factors for cardiac arrest, three of which are modifiable, possibly to decrease intubation-related cardiac arrest prevalence and 28-day ICU mortality.

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 it
