How do you score a sleep study?
You score the number of the patient's arousals and awakenings in the study and report the arousal index (frequency per hour of sleep and the total number). The higher this index, the more tired the patient will most likely feel depending on their sleep disruption tolerance level.

What is the cutoff for sleep apnea?
Most sleep centers use a cutoff of 5-10 episodes per hour. The severity of OSA is arbitrarily defined and differs widely between centers. Recommendations for cutoff levels on AHI include 5-15 episodes per hour for mild, 15-30 episodes per hour for moderate, and more than 30 episodes per hour for severe.
What is a good CPAP score?
Normal: Fewer than 5 breathing events per hour of sleep. Mild sleep apnea: 5 to 14.9 breathing events per hour of sleep. Moderate sleep apnea: 15 to 29.9 breathing events per hour of sleep. Severe sleep apnea: 30 or more breathing events per hour of sleep.
What is a good AHI score?
An AHI less than 5 is considered normal, and some patients with severe sleep apnea may be told by their doctor that they can accept even higher numbers so long as they're feeling more rested each morning, experiencing fewer symptoms and their AHI is progressively decreasing.
Will Medicare pay for a second sleep study?

While there is no set time to repeat a sleep apnea test, many doctors recommend an updated test every 5 years. Returning sleep apnea symptoms, changes in lifestyle, or changes in CPAP therapy are good indicators that a new sleep study test is required.
How many apnea events per hour is normal?
That's because it's considered normal for everyone to have up to four apneas an hour. It's also common if your AHIs vary from night to night. For some CPAP users, even higher AHIs are acceptable, depending on the severity of your sleep apnea.
What is the highest AHI score?
The Apnoea–Hypopnea Index (AHI) is used to classify the severity of the illness: mild AHI 5 to <15; moderate 15 to <30; and severe 30 or more [5]. It is well known that patients with severe OSA have higher morbidity and mortality rates compared to those with mild or moderate levels [6,7].
How many events per hour is considered sleep apnea?
Obstructive sleep apnea is classified by severity: Severe obstructive sleep apnea means that your AHI is greater than 30 (more than 30 episodes per hour) Moderate obstructive sleep apnea means that your AHI is between 15 and 30. Mild obstructive sleep apnea means that your AHI is between 5 and 15.
