What AHI value would indicate severe disease?

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

Answer: (B)

AHI measures how many apnea and hypopnea events occur per hour of sleep. It’s used to grade how severe a person’s sleep-disordered breathing is. In adults, the typical categories are: mild around 5–15 events per hour, moderate around 15–30, and severe when the count exceeds 30. So a value greater than 30 indicates severe disease. The other ranges correspond to milder forms: 16–30 is moderate, 5–15 is mild, and 1–5 is usually considered normal to minimal. Clinically, an AHI over 30 signals substantial disruption and higher health risk, often prompting stronger treatment approaches.
