An index of 5 to 14 indicates a mild level of breathing–and sleep–disturbance. From 15 to 30 is moderate; greater than 30 is severe. The associated drops in blood oxygen levels, known as desaturations, are also measured and categorized. Normal saturation is around 95 percent.

Can I test myself for sleep apnea?
