What AHI range defines mild sleep apnea?

Understanding AHI is the key to interpreting sleep apnea severity. The apnea-hypopnea index counts how many breathing pauses (apneas) and shallow breaths (hypopneas) occur per hour of sleep. Mild sleep apnea corresponds to roughly 5 to 15 events per hour. That makes the option describing about five to fifteen episodes per hour the best match. The other ranges reflect normal breathing with few or no events (<5), moderate sleep apnea (about 15–30), and severe sleep apnea (30 or more).
