Which is used to DIAGNOSE sleep apnea?
Show answer and explanation
Correct answer: B. Apnea-hypopnea index
- A. Incorrect. Mallampati score assesses airway anatomy for difficult intubation risk — not a sleep apnea diagnostic test.
- B. Correct. The gold standard for DIAGNOSING sleep apnea is overnight polysomnography (nocturnal sleep observation), monitoring multiple physiological parameters during sleep.
- C. Incorrect. The apnea-hypopnea index (AHI) is the metric used to SCORE sleep apnea severity from the study — a severity measure, not the diagnostic tool itself.
- D. Incorrect. Respiratory disturbance index is another scoring metric derived from sleep studies, not the test itself.
