Abstract
Persistent pulmonary hypertension of the newborn (PPHN) remains a serious disorder with significant mortality and long term morbidity. Inhaled nitric oxide is the only approved vasodilator therapy in neonates, but 40% of infants are non-responders. Recent biological evidence has enhanced our understanding of the cellular mechanisms involved in cardiopulmonary transition at birth, paving the way for potential alternate therapies as published in recent reviews. Optimal clinical care of infants with PPHN necessitates a comprehensive understanding and evaluation of cardiopulmonary hemodynamics. Targeted neonatal echocardiography (TnECHO) is increasingly being implemented to guide clinical decision making. The purpose of this review is to outline the role of TnECHO in better defining the cardiopulmonary physiology in PPHN and its application in clinical practice. In addition we briefly review the physiology, pathogenesis and novel therapeutic agents currently under investigation for management of PPHN. Keywords: Cardiovascular physiology, hemodynamics, persistent pulmonary hypertension of the newborn, targeted neonatal echocardiography, vasodilator

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 it
