How Is AHI Measured?

The apnea-hypopnea index (AHI) represents the average number of apneas and hypopneas you experience each hour during sleep. To measure it, doctors divide the total number of apneic and hypopneic events 5 by the total number of hours you were asleep. To register as an event, an apnea or hypopnea must last at least 10 seconds or longer.

What does AHI stand for in sleep study?

What is AHI in sleep?

The apnea-hypopnea index (AHI) is a diagnostic tool for determining the presence and severity of obstructive sleep apnea (OSA).

Why is it important to note the shortcomings of the AHI?

It is important to note these shortcomings of the AHI, because they can affect treatment . If doctors rely solely on AHI when recommending treatment, it may lead them to overlook other aspects of the person’s health history and their related symptoms. For example, for people with a high AHI but no daytime sleepiness, common OSA treatments may be less effective at reducing the risk of hypertension 8 or related cardiovascular conditions. Scientists are still debating how best to incorporate other diagnostic criteria, such as daytime sleepiness, blood oxygen levels, and blood pressure, for a fuller picture of OSA.

Is an AHI of one or more sufficient to diagnose obstructive sleep apnea?

While five is the cutoff for adults, an AHI of one or above is sufficient to diagnose obstructive sleep apnea in children. Children breathe faster than adults in order to support their faster metabolism and smaller lung capacity. This is why even one apneic event can have more of an impact for a child.

Is AHI accurate?

Moreover, since the AHI is calculated during one night in a sleep lab, it might not be accurate for someone whose AHI changes from night to night.

Does AHI take into account OSA?

While the AHI can help doctors diagnose OSA, it does not take into account all factors which may point to the severity, or existence, of OSA.
