Which AHI category corresponds to mild sleep apnea?

• A. 5-14 events/hour.
• B. <5 events/hour.
• C. 15-29 events/hour.
• D. ≥30 events/hour.

Answer: (A)

Mild sleep apnea is defined by an AHI in the range of 5 to 14 events per hour. The AHI, or Apnea-Hypopnea Index, counts how many times per hour your sleep includes pauses in breathing (apneas) or shallow breathing (hypopneas). Values below 5 are considered normal, 5–14 is mild, 15–29 is moderate, and 30 or more is severe. This threshold helps clinicians categorize severity to guide treatment decisions.
