Pathophysiology
Clinical meaning
PPHN: Nitric Oxide Pathway involves alterations in airway structure, gas exchange, or pulmonary vascular function. PPHN pathophysiology includes changes in ventilation-perfusion matching, airway resistance, and pulmonary compliance. Connect PPHN: Nitric Oxide Pathway to bedside cues you will reassess first: vitals trends, work of breathing, perfusion, mentation, and pain or ischemic equivalents when relevant. Boards reward recognizing when subtle instability outweighs reassurance, then selecting nursing actions that protect airway, circulation, and neurologic status before routine tasks.
