When is it most critical to assess for signs of respiratory distress in pediatric patients?

The most critical time to assess for signs of respiratory distress in pediatric patients is following intubation. After intubation, the airway is secured, but the patient is at high risk for various complications related to ventilation, tube placement, and potential trauma to the airway. Monitoring closely during this time is essential to ensure proper tube position, adequate ventilation, and to quickly identify any signs of respiratory distress that may arise, such as changes in oxygen saturation, breathing patterns, or the presence of stridor.

While it's important to observe for respiratory distress in other scenarios such as after surgery, during medication administration, and during respiratory therapy, the immediate post-intubation period is particularly critical due to the invasive nature of the procedure and the subsequent need for careful monitoring to detect any acute complications that could affect the child's breathing.
