What does it mean if an airway is occluded?

An occluded airway refers to a situation where the passage is blocked or closed, preventing air from moving freely in and out of the lungs. This condition can severely impede a person's ability to breathe and may lead to critical complications if not addressed promptly.

Understanding airway occlusion is essential in emergency medical situations, as swift recognition and intervention are required to restore airway patency and ensure adequate ventilation. An occluded airway could be due to foreign objects, swelling from an allergic reaction, or other obstructive conditions.

The other options describe varying degrees of airway status that do not accurately represent what it means for an airway to be occluded. An airway described as open and clear indicates unrestricted airflow, while a partially blocked airway still allows for some passage of air, and swelling suggests a physiological change rather than a complete blockage.
