How to get a bloodless intra-cardiac field in mini-invasive cardiac surgery
Bibliographic record
Abstract
Remote cannulation was realized in 4 porcine experiments (75 ± 3 kg) with percutaneous venous access, serial dilation up to 18F and insertion of either 19F thin wall, wire wound cannula or a smaller, virtually wall-less (24F Smartcanula ST). A standard MECC pump set with a centrifugal pump and a hollow fiber membrane oxygenator, but no in-line reservoir was used. Pump flow and the required pump inlet pressure were recorded for increasing pump speed from 1500 RPM to 3500 RPM (500 RPM increments). Pump flow accounted for 1.2 ± 0.2 l/min for wall-less versus 1.2 ± 0.2 l/min for thin wall at 1500 RPM, 3.5 ± 0.4 versus 3.1 ± 0.4 at 2500 RPM, 5.6 ± 0.4 versus 4.2 ± 0.7 at 3500 RPM. Pump inlet pressure accounted for -4 ± 19 mmHg versus 2 ± 13 mmHg for 1500 RPM, -35 ± 19 versus -89 ± 27 at 2500 RPM, and -90 ± 21 versus -220 ± 29 for 3500 RPM. For a pump inlet pressure of -88 mmHg, the mean pump flow was 4.5 ± 0.8 l/min for the new smaller virtually wall-less venous cannula versus 3.1 ± l/min for control (p < 0.05).

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.
