Abstract

fetched live from OpenAlex

Arterial pulse pressure (PP) respiratory variation is a good predictor of fluid responsiveness in ventilated patients. Recently, it has been shown that variation in PP may correlate with variation in pulse oximetry plethysmographic (POP) waveform amplitude, as they both depend on the stroke volume. We designed a prospective study to evaluate the correlation between respiratory arterial PP variation and POP waveform amplitude variations in ventilated patients and the influence of acute lung injury (ALI) in this relationship.

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 distilled prediction

Teacher imitation

Not 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.
