Abstract
PURPOSE OF REVIEW: Pulmonary artery rupture is probably the most devastating complication associated with the use of the pulmonary artery catheter. This rare but disastrous situation requires a clear intervention plan. RECENT FINDINGS: The initial presentation of pulmonary artery ruptures may be as obvious as a massive pulmonary hemorrhage or as subtle as a cough associated with minimal hemoptysis, or it may even be totally asymptomatic. A patient presenting any clinical manifestation of pulmonary artery rupture may develop a pulmonary artery false aneurysm, which is the accumulation of blood in an aneurismal sac compressed by lung parenchyma. This condition requires intervention because delayed hemorrhage may occur and recurrence can be massive and fatal. Following an initial episode of suspected pulmonary artery rupture, the patient should undergo immediate radiological investigation. If a diagnosis of pulmonary artery false aneurysm is confirmed, selective angiographic embolization helps reduce morbidity and mortality. SUMMARY: The incidence of pulmonary artery ruptures is probably underestimated because many hemoptysis episodes or radiological infiltrations associated with pulmonary artery catheter use are not investigated. Also, the natural evolution of the pulmonary artery false aneurysm is unknown. The incidence of spontaneous healing, bleeding recurrence or asymptomatic persistence is unknown following formation of a pulmonary artery false aneurysm.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
