Abstract

fetched live from OpenAlex

Background and aims: In this case a 14 year old boy with a neuromuscular disorder[NMD] presented to PICU post-cardiopulmonary arrest with R pneumothorax and grade 4 liver laceration. Prior to this event his respiratory care was in accordance with guidelines for children with NMD. He used nocturnal non-invasive ventilation [NIV], percussions & vibration, and manually assisted cough from age 2. He added bag & mask breath stacking from age 4 and changed to mechanical insufflation-exsufflation [MI-E] at age 7. His L lung had been collapsed since age 8. Aims: Facilitate lung volume recruitment [LVR] and clear secretions using minimal pressures and no external thoracic compression. Wean the patient from invasive ventilation to nocturnal NIV. Methods: Implementation of a novel treatment technique - active-assisted deep breathing[AA-DB]. AA-DB uses positive pressure from the ventilator to assist the patient’s active efforts to achieve a breath 50% > resting tidal volume[Vt]. The treatment involves having the patient perform sets of AA-DB to a target-Vt. Results: AA-DB was an effective treatment during invasive ventilation and NIV. Ability to do AA-DB was used to guide pressure settings. Efficiency in performing AA-DB sets was used to assess readiness for extubation and weaning of NIV. AA-DB has replaced MI-E in his home program. AA-DB volumes have increased over time. He has spent fewer days in hospital this year than previous. Conclusions: AA-DB was, and continues to be, an effective treatment for this young man with NMD who was previously managed with MI-E. AA-DB warrants further investigation.

Not 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.
