What AHI value would indicate a moderate disease?

What AHI value would indicate a moderate disease?

• A. >30
• B. 16-30
• C. 5-15
• D. 1-5

Answer: (B)

An apnea-hypopnea index (AHI) is the number of apnea and hypopnea events per hour of sleep, used to grade the severity of sleep-disordered breathing. Moderate disease corresponds to 16 to 30 events per hour. This range reflects a substantial level of breathing interruptions during sleep, more significant than mild (typically 5–15 events/hour) but not as extreme as severe (greater than 30 events/hour). Understanding these thresholds helps explain why this range is labeled moderate and guides considerations for treatment and management.
