Severity of Sleep Apnea

severity of sleep apneaThere are three levels of severity of sleep apnea – mild, moderate and severe.

The difference between these levels is determined by the number of times a person stops breathing while sleeping.

There is a scale called the AHI scale (AHI stands for Apnea Hypopnea Index).  It is simply the number of times a person stops breathing for 10 seconds or more, during an hour of sleep.

MILD

If a person stops breathing between five and 15 times in an hour, they have a case of mild sleep apnea.

MODERATE

If they stop breathing between 15 and 30 times, their case is moderate.

SEVERE

When a person stops breathing more than 30 times in an hour of sleep, they have a severe case.
