Pulmonary Thromboses in Pediatric Acute Respiratory Distress Syndrome
Bibliographic record
Abstract
Pediatric ARDS continues to be a management challenge in the ICU with prolonged hospitalizations and high mortality. Thromboembolic pulmonary embolism and in situ pulmonary artery thrombosis might represent underappreciated thrombotic processes for a subset of these patients. Although well described in the adult literature, descriptions of pulmonary thromboses with pediatric ARDS are limited to case reports. However, many risk factors for pulmonary thromboses are present in children with ARDS (eg, coagulopathy, endothelial injury, central venous catheters, concomitant inflammatory diseases), suggesting a much higher incidence is plausible. Based on an interpretation of animal, pediatric, and adult data, we propose a diagnostic algorithm to facilitate a timely and accurate diagnosis. Observing an alveolar dead space fraction ≥ 0.25, or either a 50% increase in physiologic dead space/tidal volume or a central venous saturation ≤ 60% over 24 h, triggers the algorithm. Together with targeted heparin treatment and right ventricular afterload reduction, clinical outcomes might improve if this particular patient subgroup can be identified early. While anticoagulation is recommended in adults with confirmed pulmonary embolism and low early mortality risk, data for children are limited.

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.
