Airway Obstruction describes which condition?

Airway Obstruction describes which condition?

• A. Blockage preventing speech
• B. Blockage preventing airflow
• C. Blockage preventing oxygen transport in blood
• D. Blockage preventing airway lubrication

Answer: (B)

Airway obstruction is a blockage in the conducting airways that prevents air from moving in and out of the lungs. The essential idea is that the problem is with airflow itself—air can't reach the lungs to be used for gas exchange, or be expelled if the airway is blocked. This is different from issues with oxygen transport in the blood (gas exchange at the alveoli) or with lubrication of the airway, which are about different parts of the respiratory process. A blocked airway, such as from choking or swelling, directly compromises airflow, leading to signs of distress and potential hypoxia if not resolved.
