Abstract
<b>Introduction:</b> High intensity non-invasive positive pressure ventilation (HI-NPPV) is an algorithm of non-invasive ventilation that has been shown to improve partial pressure of carbon dioxide (PaCO<sub>2</sub>), health-related quality of life and mortality in hypercapnic chronic obstructive pulmonary disease (COPD) patients. <b>Objective:</b> Assess 3 months of HI-NPPV in stable hypercapnic COPD patients. <b>Methods:</b> A single arm, non-randomized pilot study of HI-NPPV. Patients were eligible if they had clinically stable COPD and daytime arterial PaCO<sub>2</sub> >50 mmHg. <b>Results:</b> Nine patients completed therapy. Patient characteristics: 2 male: 7 female, mean age of 64.4 years (SD ±6.6), mean forced expiratory volume in 1 second (FEV<sub>1</sub>) of 26% (SD±6.73), 8 patients on long term oxygen therapy (LTOT) and a median body mass index (BMI) of 26.6 (interquartile range [IQR] 25.5 - 32.5). <b>Outcomes:</b> There was a mean reduction in daytime PaCO<sub>2</sub> by 4.66 mmHg (<i>p</i>=0.01) and bicarbonate by 2.16 mmHg (<i>p</i>=0.005). There was no statistically significant difference in lung function, maximal inspiratory pressures or 6 minute walk distance. There was no statistically significant difference in sleep duration, efficiency or percentage of sleep stage 3 ( N3) or rapid eye movement (REM). The Chronic Respiratory Questionnaire (CRQ) showed a trend towards improvement with an increase of 2.69 points (<i>p</i>=0.054), the dyspnea domain showed a statistically significant improvement (<i>p</i>=0.03). The Calgary Sleep Apnea Quality of Life Index (SAQLI) detected an improvement in daily functioning (<i>p</i>=0.007). The Severe Respiratory Insufficiency (SRI) Questionnaire showed a trend to improvement overall (<i>p</i>=0.05). Four patients had COPD exacerbations during the follow up period. <b>Conclusions:</b> HI-NPPV is able to substantially reduce PaCO<sub>2</sub> in hypercapnic COPD patients; we detected a positive effect on quality of life measures with no significant change in sleep quality.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
