Abstract
Improvement in airway function in response to bronchodilator therapy is generally confirmed by simple spirometry. However, improvements in maximal expiratory flow rates have been shown to correlate poorly with important patient-centred outcomes, such as reduced exertional dyspnoea and improved exercise performance. Recent studies have suggested that attendant reductions in end-expiratory lung volume as a result of bronchodilator-induced improvements in lung emptying may be more closely associated with symptom relief and increased exercise capacity than traditional spirometric indices. To the extent that chronic lung hyperinflation and the superimposition of acute dynamic hyperinflation (in response to increased ventilation or expiratory flow limitation) result in excessive loading and weakening of the inspiratory muscles, then pharmacological lung volume reduction should have important mechanical and sensory benefits for the patient. The present article will examine the mechanisms of lung deflation following short-term bronchodilator therapy. The physiological links between reduced hyperinflation, improved dyspnoea and exercise endurance will be examined, and the emerging evidence for the additive effects of combining various modern pharmacological therapies will be reviewed.

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 it
