Combined Positive and Negative Pressure Ventilation in the Management of Severe Respiratory Distress Syndrome in Newborn Infants
Bibliographic record
Abstract
Eleven newborn infants with severe respiratory distress syndrome (RDS) were artificially ventilated with an intermittent positive pressure respirator while a continuous negative pressure of ––4 to ––8 cm H<sub>2</sub>O was maintained about the chest; thereby achieving the equivalent positive of pressure ventilation. Although only two infants ultimately survived, arterial oxygen tension was improved in all patients, with a mean rise of 69.8 ± 17.3 mm Hg. Simultaneously, the alveolar-arterial oxygen difference fell·by a mean of 63.7 ± 18.4 mm Hg, even though the infants had not improved on preceding trials of both intermittent negative and intermittent positive pressure ventilation alone. These changes are significant at a level of p < 0.01. The maintenance of a continuous transpulmonary pressure gradient is an effective method for improving arterial oxygenation in infants requiring mechanical ventilation for the respiratory failure of RDS.

How this classification was reachedexpand
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; a candidate call from one teacher head, not a consensus.
