We hypothesize that breathing disorder related arousal index (B‐ArI) can differentiate sleep breathing disorder from simple snorer when apnea hypopnea index (AHI) is low. We studied 54 patients using polysomnography. Breathing disorder related arousal (B‐Ar) was defined as arousal accompanied by apnea, hypopnea, desaturation or snort. Mean AHI was 44.2 ± 34.0/h, and B‐ArI correlated significantly with AHI, desaturation index, percentage total sleep time with SpO 2 below 90%. Breathing disorder related arousal index was greater than AHI when AHI was below 20. In 11/54 patients, AHI was below 10, and B‐ArI more than 10. Nasal continuous positive airway pressure was applied to six patients and showed reduced B‐ArI. Breathing disorder related arousal index may be one of the useful indices for the diagnosis of sleep breathing disorder when AHI is less than 10.
