Describe the mechanisms by which hypoxemia, hypercarbia, and congenital cardiac abnormalities contribute to respiratory distress and respiratory failure in pediatric cardiac patients.

Identify early and late clinical signs of respiratory compromise, including changes in respiratory rate and effort, oxygenation, heart rate, perfusion, breath sounds, and mental status. 

Apply a systematic airway, breathing, and circulation assessment to recognize pediatric cardiac patients at risk for respiratory failure and determine priorities for immediate intervention. 

Analyze clinical findings to differentiate common causes of respiratory deterioration in pediatric cardiac patients, including pulmonary edema, respiratory infections, post-extubation stridor, and pleural effusions.

Evaluate respiratory support and stabilization strategies for pediatric cardiac emergencies by selecting appropriate interventions to improve oxygenation, ventilation, and overall cardiopulmonary function.
