Sleep apnea is the second most common sleep disorder in the world, and health experts are becoming more concerned about its effects as our population ages. To better understand and illustrate the impact of this growing epidemic, we’ve compiled the collection of sleep apnea statistics you’ll find below.
We’ll look at its prevalence, who it affects most, and how it impacts us both in the short and long term. We’ll also provide you with several CPAP statistics, including how many people use CPAP and its success rate. Lastly, we’ll examine the numbers behind alternative methods for treating sleep apnea.

Sleep Apnea Treatment
Although Continuous Positive Airway Pressure is the go-to treatment, there are actually many ways to manage sleep apnea. Some solutions, such as Positional Therapy, can be done on your own and may be enough to improve mild cases. Some approaches may work better for a specific type of sleep apnea. If you have severe sleep apnea, your doctor may ask that you undergo multiple types of treatment.
Continuous Positive Airway Pressure (CPAP) Statistics
- While the exact amount is not known due to the number of people who quit CPAP therapy early, manufacturers have estimated that at least 8 million people sleep with a CPAP machine each night.
- It is estimated that between one-third and one-half of all people who start CPAP will quit within the first year.
- A 2014 scientific review found that CPAP-compliant people have an 80% success rate with their treatment.
- Ideally, healthcare providers want you to use your CPAP machine for at least 7 hours per night, but most insurance companies ask you to use it for a minimum of 4 hours a night, 21 nights a month.
- People who regularly sleep with their machine may have their risk of premature death decreased by as much as 61%. This 2022 study also projected that CPAP therapy decreases a person’s risk for heart failure by 77%.
- CPAP therapy could reduce your risk of getting into a car accident by 70% if you use your CPAP device for more than four hours each night.
- CPAP can significantly improve your quality of life due to better sleep. In one study, more than 90% of participants saw an improvement in at least one area of their lives.
- There are at least four other types of Positive Airway Pressure therapy– EPAP, APAP, BiPAP, and ASV.

- One study found that Mandibular Advancement Devices, a form of OAT, reduced the number of breathing events in 86% of participants.
- During the above study, 33% saw their AHI score cut in half.
- In the early 2000s, only 0.2% of people with OSA underwent surgery, but this has likely increased in recent years due to new advancements.

Frequently Asked Questions
How Many People Use CPAP?
How Many People Have Sleep Apnea?
Experts state that there are more than 936 million cases worldwide, many of which are undiagnosed. In the USA, health officials estimate that more than 30 million Americans are affected, over 9% of the population.
What Are the Different Types of Sleep Apnea?
There are three types of sleep apnea– Obstructive (OSA), Central (CSA), and Complex (CoSA). Obstructive is caused by airway blockages during sleep. CSA occurs due to an issue with the brain or respiratory muscles. CoSA arises when a person undergoing CPAP treatment for OSA also develops CSA.
Is Snoring Common in Sleep Apnea?
Snoring is common in some cases but not so much in others. For example, 94% of people with Obstructive Sleep Apnea snore, but it’s much less common for people with Central Sleep Apnea.
What Is the CPAP Success Rate?
If you use your CPAP machine regularly, CPAP therapy is successful in at least 80% of cases. However, many people struggle to remain CPAP-compliant, with at least a third of all CPAP owners quitting within months.
What Percentage of People Have Sleep Apnea?
The estimated percentage of adults with sleep apnea is between 10 and 15% worldwide. The percentage of childhood cases is far lower, with 1- 6% of children having OSA and 1-5% having CSA.
What Are the Treatment Options for Obstructive Sleep Apnea?
Treatment for OSA usually starts with CPAP therapy and lifestyle changes. However, there are alternative treatments as well, including Oral Appliance Therapy, Positional Therapy, surgery, and nerve implants.
How Is Severe Sleep Apnea Treated?
Doctors often prescribe CPAP therapy and lifestyle changes for anyone impacted by sleep apnea. However, more severe cases usually require high-pressure CPAP, which may also be paired with other treatment methods, such as surgery or Oral Appliance Therapy.
After reading through these sleep apnea statistics, you may wonder if you could be one of the millions of people with an undiagnosed case. If you or your partner suspect you have sleep-disordered breathing, we encourage you to speak with your doctor about completing an at-home sleep study.
