Abstract

fetched live from OpenAlex

RATIONALE: Treatments with home based compressor/nebulizer systems can offer very different delivery characteristics. We evaluated a new, reusable BAN (AeroEclipse-XL®, Trudell Medical International) in breath-actuated mode with its portable (Ombra®) battery-compressor. METHODS: The nebulizer-on-test (n=5/group) was filled with 2.5-mL, 1.0 mg/mL albuterol (Ventolin®, GSK Canada Inc.), and connected to a breathing simulator (ASL5000, IngMar Medical, Pittsburgh, PA) mimicking adult tidal breathing (V t = 600-mL; duty cycle = 33%; rate = 10 cycles/min). Emitted aerosol was captured on a filter at the mouthpiece, replaced at minute intervals until onset of sputtering, defining run time. Recovery/assay of salbutamol was undertaken by HPLC-UV spectrophotometry. Fine droplet fraction (FDF ) was the product of total mass and FDF . Comparative measurements were made with the Sprint® (PARI, Germany) and MicroPlus® (Philips-Respironics, Germany) nebulizers using PARI BOY® Mobile S® and Inspiration Micro Elite® portable compressors respectively. RESULTS: See Table CONCLUSIONS: The BAN/Ombra® system provided highly respirable aerosol with FDM substantially greater than the benchmark systems. Its run time reflects the fact that aerosol is only delivered during inhalation and not wasted to the environment.

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.
