Trach tubes designed to maximize safety may increase risk to ventilated patients
Bibliographic record
Abstract
Dual-cannulae tracheostomy tubes with low-pressure cuffs, such as the Shiley LPC, are widely regarded as inherently safer than single lumen tubes with low-volume cuffs. For the patient who undergoes tracheostomy for failure to wean from mechanical ventilation, however, the insertion of a tube that occupies a large amount of space within the trachea can delay subsequent efforts to liberate him from the ventilator. With an aim to promote more timely rehabilitation of ventilated patients, London Ontario's University Hospital has been inserting the Bivona TTS, a single lumen tube with an elastic cuff, during tracheostomy. This allows caregivers to better exploit the benefits of a functional upper airway early during the weaning process, which may reduce complications associated with prolonged mechanical ventilation. We urge clinical studies to determine how the choice of initial tracheostomy tube can affect rehabilitation strategies and important patient outcomes.

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.
