Safety of Berlin Heart EXCOR Pump Changes in the PICU
Bibliographic record
Abstract
OBJECTIVE: To describe whether Berlin Heart EXCOR Pediatric pump changes in the ICU are associated with infection, hemodynamic and ventilatory instability, and neurologic injury. DESIGN: Retrospective, descriptive chart review. SETTING: PICU in a quaternary care children's hospital. PATIENTS: Eight patients were supported on Berlin Heart EXCOR Pediatric pumps due to cardiomyopathy or cardiogenic shock. Two patients were supported with left ventricular assist devices, five had biventricular assist devices, and one required a univentricular assist device. INTERVENTIONS: A team of cardiac surgeons, pediatric intensivists, and operating room nurses conducted sixteen pump changes in the pediatric intensive care unit. Patients were monitored for deleterious effects for 5 days following the change. MEASUREMENT AND MAIN RESULTS: For the first 48 hrs following the EXCOR pump change, no patients exhibited acute neurologic deficits or escalation of hemodynamic or ventilatory support. Over the first 5 days, no blood cultures were positive for microbes. CONCLUSIONS: Berlin Heart EXCOR Pediatric pump changes in the pediatric intensive care unit appear to be a safe procedure when conducted by a highly specialized team.

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.
