In deep sedation, which statement best describes airway protection?

• A. Cannot be easily aroused, but respond purposefully after repeated verbal/painful stimulus.
• B. Ventilatory function may be impaired.
• C. CV maintained.
• D. May lose protective airway reflexes.

Answer: (D)

In deep sedation, the level of consciousness and protective reflexes are reduced because the central nervous system is more suppressed. Airway protection relies on reflexes like coughing, gagging, and the ability to maintain a patent airway even with secretions or small amounts of material in the back of the throat. When these protective reflexes diminish, the patient may no longer adequately guard the airway, increasing the risk of airway obstruction and aspiration.

While ventilatory function can be impaired and cardiovascular status can vary with sedation depth, the statement that directly describes airway protection is that protective airway reflexes may be lost. This highlights the key safety concern in deep sedation: diminished reflexes that protect the airway require readiness to manage the airway.
