After endotracheal tube placement, which observation best suggests improved perfusion?

Explanation:
Perfusion is about delivering oxygen-rich blood to tissues. After securing the airway and providing ventilation, tissues receive better oxygenation, and the skin often becomes pink and warm as perfusion improves. Improved skin color is the clearest, most direct sign that tissue perfusion has improved. Worsening respiratory distress signals ongoing airway/ventilation problems, not perfusion. An increased heart rate can happen with stress or hypoxia but doesn’t confirm improved perfusion. Subcutaneous emphysema indicates air leakage or trauma, not tissue perfusion status.
