Extrinsic tracheotomy tube compression in a patient with upper airway obstruction: A case series
Bibliographic record
Abstract
ABSTRACT Tracheostomies are commonly performed procedures for a variety of indications, including to secure a patient’s airway when endotracheal intubation is not advisable. Though routine, tracheostomies are not possible without complications. We present the first reported cases of patients with idiopathic external compression of a tracheostomy tube following a tracheostomy. In both cases, standard algorithms for the management of tracheostomy tube occlusion were followed. In both patients, subsequent inability to reinsert the cannula prompted bedside bronchoscopy. The first patient demonstrated a 40% to 50% occlusion of the tracheostomy tube as a result of the tube itself being compressed externally. The occlusion did not resolve, despite change of the entire tracheostomy tube, until a tracheal ring was excised. The second patient had a bronchoscopy at the bedside, revealing a 20% compression of the tracheostomy tube that was managed conservatively. There are several complications that can arise when performing a tracheostomy, but no previous cases have been published describing external compression of the tracheostomy tube.

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.
