Combined metabolic parameters and gas exchange to predict morbidity after extracorporeal circulation
Bibliographic record
Abstract
Under normal resting conditions, the oxygen delivery (DO 2 ) matches the overall metabolic demands of the organs, the oxygen consumption (VO 2 ) is about 25% of the DO 2 , and energy is produced basically through the aerobic mechanism. In cardiac surgery with extracorporeal circulation (ECC), several factors (for example, hemodilutional anemia, myocardial stunning resulting in a low cardiac output (CO)) can determine an imbalance between O 2 demand and DO 2 and may affect the outcome. Below the critical DO 2 there is a linear decrease of both VO 2 and CO 2 production (VCO 2 ), but due to the anaerobic VCO 2 the respiratory quotient increases. This study is aimed to evaluate the role of O 2 and CO 2 derived parameters to predict postoperative morbidity in cardiac surgery.

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.
