Abstract
Airway anatomy and physiology are altered in obesity, and an understanding of these changes is key to appropriate airway management. Longitudinal studies of pulmonary function have shown reduction in pulmonary tests with obesity. The functional residual capacity (FRC) is reduced by the conduct of general anaesthesia. In the obese, the resting metabolic rate, oxygen consumption and also carbon dioxide production are all increased, compounding the reduction in FRC. In addition to acting as an oxygen store, FRC is important in splinting small airways. Respiratory mechanics are affected even in moderate obesity. Prediction of difficulty: Mallampati score and neck circumference are better predictors than body mass index (BMI) and a history of obstructive sleep apnoea (OSA), but their predictive value is not strong. Difficult mask ventilation and difficult intubation are uncommon. Awake intubation is worthwhile if difficulty is expected, because of the rapid desaturation problem.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
