==Mechanism==
When breathing is paused, carbon dioxide builds up in the bloodstream. [[Chemoreceptor]]s in the bloodstream note the high carbon dioxide levels. The brain is signaled to awaken the person, which clears the airway and allows breathing to resume. Breathing normally will restore oxygen levels and the person will fall asleep again.<ref>{{cite book|last=Green|first=Simon|title=Biological Rhythms, Sleep and Hyponosis|date=8 February 2011|publisher=Palgrave Macmillan|location=England|isbn=978-0-230-25265-3|page=85}}</ref> This carbon dioxide build-up may be due to the decrease of output of the brainstem regulating the chest wall or pharyngeal muscles, which causes the pharynx to collapse.<ref name=Pur2018/> People with sleep apnea experience reduced or no [[slow-wave sleep]] and spend less time in [[REM sleep]].<ref name=Pur2018>{{cite book|title=Neuroscience|last=Purves|first=Dale|isbn=978-1-60535-380-7 |publisher=Oxford University Press |edition=Sixth|location=New York|oclc=990257568|date = 4 July 2018}}{{page needed|date=March 2021}}</ref>

Despite this{{Which|date=February 2021}} medical consensus, the variety of apneic events (e.g., hypopnea vs apnea, central vs obstructive), the variability of patients' physiologies, and the inherent shortcomings and variability of equipment and methods, this field is subject to debate.<ref>{{cite journal | vauthors = Redline S, Budhiraja R, Kapur V, Marcus CL, Mateika JH, Mehra R, Parthasarthy S, Somers VK, Strohl KP, Sulit LG, Gozal D, Wise MS, Quan SF | title = The scoring of respiratory events in sleep: reliability and validity | journal = Journal of Clinical Sleep Medicine | volume = 3 | issue = 2 | pages = 169–200 | date = March 2007 | pmid = 17557426 | doi = 10.5664/jcsm.26818 | doi-access = free }}</ref>

====Obstructive sleep apnea====
{{Main|Obstructive sleep apnea}}
[[File:ObstructiveApnea.png|thumb|upright=1.3|Screenshot of a PSG system showing an obstructive apnea]]
[[File:New no obstruction.png|thumb|No airway obstruction during sleep]]
[[File:Airway obstruction.png|thumb|Airway obstruction during sleep]]
Obstructive sleep apnea (OSA) is the most common category of sleep-disordered breathing. The muscle tone of the body ordinarily relaxes during sleep, and at the level of the throat, the human airway is composed of collapsible walls of soft tissue that can obstruct breathing. Mild occasional sleep apnea, such as many people experience during an [[upper respiratory infection]], may not be significant, but chronic severe obstructive sleep apnea requires treatment to prevent low blood oxygen ([[hypoxemia]]), [[sleep deprivation]], and other complications.{{medical citation needed|data=February 2024|date=February 2024}}

Individuals with low muscle-tone and soft tissue around the airway (e.g., because of obesity) and structural features that give rise to a narrowed airway are at high risk for obstructive sleep apnea. The elderly are more likely to have OSA than young people. Men are more likely to develop sleep apnea than women and children are, though it is not uncommon in the last two population groups.<ref>{{cite web | url = http://www.nhlbi.nih.gov/health/dci/Diseases/SleepApnea/SleepApnea_WhoIsAtRisk.html | title = Sleep Apnea: Who Is At Risk for Sleep Apnea? | work = NHLBI: Health Information for the Public | publisher = U.S. Department of Health and Human Services | url-status = live | archive-url = https://web.archive.org/web/20100721082753/http://www.nhlbi.nih.gov/health/dci/Diseases/SleepApnea/SleepApnea_WhoIsAtRisk.html | archive-date = 21 July 2010 }}</ref>

The risk of OSA rises with increasing body weight, active smoking and age. In addition, patients with diabetes or "borderline" diabetes have up to three times the risk of having OSA.{{medical citation needed|data=February 2024|date=February 2024}}

Common symptoms include loud [[snoring]], restless sleep, and sleepiness during the daytime. Diagnostic tests include home [[oximetry]] or [[polysomnography]] in a sleep clinic.{{medical citation needed|data=February 2024|date=February 2024}}

====Central sleep apnea====
{{More citations needed|date=May 2010}}
{{Main|Central sleep apnea}}
[[File:CentralApnea.png|thumb|upright=1.3|Screenshot of a PSG system showing a central apnea]]
In pure central sleep apnea or [[Cheyne–Stokes respiration]], the brain's respiratory control centers are imbalanced during sleep.<ref>{{cite journal | vauthors = Yumino D, Bradley TD | title = Central sleep apnea and Cheyne-Stokes respiration | journal = Proceedings of the American Thoracic Society | volume = 5 | issue = 2 | pages = 226–36 | date = February 2008 | pmid = 18250216 | doi = 10.1513/pats.200708-129MG }}</ref> Blood levels of carbon dioxide, and the neurological feedback mechanism that monitors them, do not react quickly enough to maintain an even respiratory rate, with the entire system cycling between apnea and tachypnea, even during wakefulness. The sleeper stops breathing and then starts again. There is no effort made to breathe during the pause in breathing: there are no chest movements and no struggling. After the episode of apnea, breathing may be faster (tachypnea) for a period of time, a compensatory mechanism to blow off retained waste gases and absorb more oxygen.{{medical citation needed|data=February 2024|date=February 2024}}

While sleeping, a normal individual is "at rest" as far as cardiovascular workload is concerned. Breathing is regular in a healthy person during sleep, and oxygen levels and carbon dioxide levels in the bloodstream stay fairly constant. Any sudden drop in oxygen or excess of carbon dioxide (even if tiny) strongly stimulates the brain's respiratory centers to breathe.{{medical citation needed|data=February 2024|date=February 2024}}

In any person, hypoxia and hypercapnia have certain common effects on the body.<ref>{{cite journal | vauthors = Sicard KM, Duong TQ | title = Effects of hypoxia, hyperoxia, and hypercapnia on baseline and stimulus-evoked BOLD, CBF, and CMRO2 in spontaneously breathing animals | journal = [[NeuroImage]] | volume = 25 | issue = 3 | pages = 850–8 | date = April 2005 | pmid = 15808985 | pmc = 2962945 | doi = 10.1016/j.neuroimage.2004.12.010 }}</ref> The heart rate will increase, unless there are such severe co-existing problems with the heart muscle itself or the autonomic nervous system that makes this compensatory increase impossible. The more translucent areas of the body will show a bluish or dusky cast from [[cyanosis]], which is the change in hue that occurs owing to lack of oxygen in the blood ("turning blue"). Overdoses of drugs that are respiratory depressants (such as heroin, and other opiates) kill by damping the activity of the brain's respiratory control centers. In central sleep apnea, the effects of sleep ''alone'' can remove the brain's mandate for the body to breathe.
* Normal Respiratory Drive: After exhalation, the blood level of oxygen decreases and that of carbon dioxide increases. Exchange of gases with a lungful of fresh air is necessary to replenish oxygen and rid the bloodstream of built-up carbon dioxide. Oxygen and carbon dioxide receptors in the blood stream (called [[chemoreceptors]]) send nerve impulses to the brain, which then signals reflex opening of the [[larynx]] (so that the opening between the vocal cords enlarges) and movements of the rib cage muscles and [[Diaphragm (anatomy)|diaphragm]]. These muscles expand the [[Human thorax|thorax]] (chest cavity) so that a partial vacuum is made within the lungs and air rushes in to fill it.
* Physiologic effects of central apnea: During central apneas, the central respiratory drive is absent, and the brain does ''not'' respond to changing blood levels of the respiratory gases. No breath is taken despite the normal signals to inhale. The immediate effects of central sleep apnea on the body depend on how long the failure to breathe endures. At worst, central sleep apnea may cause sudden death. Short of death, drops in blood oxygen may trigger [[seizure]]s, even in the absence of [[epilepsy]]. In people ''with'' epilepsy, the hypoxia caused by apnea may trigger seizures that had previously been well controlled by medications.<ref name="Epilepsy and sleep apnea syndrome">{{cite journal | vauthors = Devinsky O, Ehrenberg B, Barthlen GM, Abramson HS, Luciano D | title = Epilepsy and sleep apnea syndrome | journal = Neurology | volume = 44 | issue = 11 | pages = 2060–4 | date = November 1994 | pmid = 7969960 | doi = 10.1212/WNL.44.11.2060 | s2cid = 2165184 }}</ref> In other words, a seizure disorder may become unstable in the presence of sleep apnea. In adults with [[coronary artery disease]], a severe drop in blood oxygen level can cause [[angina]], [[Heart arrhythmia|arrhythmia]]s, or heart attacks ([[myocardial infarction]]). Longstanding recurrent episodes of apnea, over months and years, may cause an increase in carbon dioxide levels that can change the pH of the blood enough to cause a [[respiratory acidosis]].{{medical citation needed|data=February 2024|date=February 2024}}

====Mixed apnea====
Some people with sleep apnea have a combination of both types; its prevalence ranges from 0.56% to 18%. The condition is generally detected when obstructive sleep apnea is treated with CPAP and central sleep apnea emerges. The exact mechanism of the loss of central respiratory drive during sleep in OSA is unknown but is most likely related to incorrect settings of the CPAP treatment and other medical conditions the person has.<ref name= ComplexRev2014>{{cite journal | vauthors = Khan MT, Franco RA | title = Complex sleep apnea syndrome | journal = Sleep Disorders | volume = 2014 | pages = 1–6 | year = 2014 | pmid = 24693440 | pmc = 3945285 | doi = 10.1155/2014/798487 | doi-access = free }}</ref>

==Management==
The treatment of obstructive sleep apnea is different than that of central sleep apnea. Treatment often starts with behavioral therapy and some people may be suggested to try a [[continuous positive airway pressure]] device. Many people are told to avoid alcohol, sleeping pills, and other sedatives, which can relax throat muscles, contributing to the collapse of the airway at night.<ref name=SleepApneaTreatments /> The evidence supporting one treatment option compared to another for a particular person is not clear.<ref name="pmid36278514">{{cite journal |last1=Pinto |first1=Ana Carolina Pereira Nunes |last2=Rocha |first2=Aline |last3=Drager |first3=Luciano F |last4=Lorenzi-Filho |first4=Geraldo |last5=Pachito |first5=Daniela V |date=24 October 2022 |editor-last=Cochrane Airways Group |title=Non-invasive positive pressure ventilation for central sleep apnoea in adults |url= |journal=Cochrane Database of Systematic Reviews |language=en |volume=2022 |issue=10 |pages=CD012889 |doi=10.1002/14651858.CD012889.pub2 |pmc=9590003 |pmid=36278514 }}</ref>

Since the palatal suture is fused in adults, regular RPE using tooth-borne expanders cannot be performed. Mini-implant assisted rapid palatal expansion (MARPE) has been recently developed as a non-surgical option for the transverse expansion of the maxilla in adults.

The "Pillar" device is a treatment for snoring and obstructive sleep apnea; it is thin, narrow strips of polyester. Three strips are inserted into the roof of the mouth (the [[soft palate]]) using a modified syringe and local anesthetic, in order to stiffen the soft palate. This procedure addresses one of the most common causes of snoring and sleep apnea&nbsp;— vibration or collapse of the soft palate. It was approved by the FDA for snoring in 2002 and for obstructive sleep apnea in 2004. A 2013 meta-analysis found that "the Pillar implant has a moderate effect on snoring and mild-to-moderate obstructive sleep apnea" and that more studies with high level of evidence were needed to arrive at a definite conclusion; it also found that the polyester strips work their way out of the soft palate in about 10% of the people in whom they are implanted.<ref name=pillar>{{cite journal | vauthors = Choi JH, Kim SN, Cho JH | title = Efficacy of the Pillar implant in the treatment of snoring and mild-to-moderate obstructive sleep apnea: a meta-analysis | journal = The Laryngoscope | volume = 123 | issue = 1 | pages = 269–76 | date = January 2013 | pmid = 22865236 | doi = 10.1002/lary.23470 | s2cid = 25875843 }}</ref>

Small shots or other treatments, sometimes in a series, are used for shrinkage, while the insertion of a small piece of stiff plastic is used in the case of surgery whose goal is to stiffen tissues.<ref name=SleepApneaTreatments/>

====Multi-level surgery====
[[Maxillomandibular advancement]] (MMA) is considered the most effective surgery for people with sleep apnea, because it increases the posterior airway space (PAS).<ref>{{cite journal | vauthors = Prinsell JR | title = Maxillomandibular advancement surgery for obstructive sleep apnea syndrome | journal = Journal of the American Dental Association | volume = 133 | issue = 11 | pages = 1489–97; quiz 1539–40 | date = November 2002 | pmid = 12462692 | doi = 10.14219/jada.archive.2002.0079 }}</ref> However, health professionals are often unsure as to who should be referred for surgery and when to do so: some factors in referral may include failed use of CPAP or device use; anatomy which favors rather than impedes surgery; or significant craniofacial abnormalities which hinder device use.<ref name="auspre01">{{cite journal |author=MacKay, Stuart |title=Treatments for snoring in adults |journal=Australian Prescriber |volume=34 |issue=34 |pages=77–79 |date=June 2011 |doi=10.18773/austprescr.2011.048 |doi-broken-date=31 January 2024 |doi-access= }}</ref>

====Potential complications====
Several inpatient and outpatient procedures use sedation. Many drugs and agents used during surgery to relieve pain and to depress consciousness remain in the body at low amounts for hours or even days afterwards. In an individual with either central, obstructive or mixed sleep apnea, these low doses may be enough to cause life-threatening irregularities in breathing or collapses in a patient's airways.<ref>{{cite book |first1=T.

Surgery on the mouth and throat, as well as dental surgery and procedures, can result in postoperative swelling of the lining of the mouth and other areas that affect the airway. Even when the surgical procedure is designed to improve the airway, such as tonsillectomy and adenoidectomy or tongue reduction, swelling may negate some of the effects in the immediate postoperative period. Once the swelling resolves and the palate becomes tightened by postoperative scarring, however, the full benefit of the surgery may be noticed.{{medical citation needed|data=February 2024|date=February 2024}}

A person with sleep apnea undergoing any medical treatment must make sure their doctor and [[Nurse anesthetist|anesthetist]] are informed about the sleep apnea. Alternative and emergency procedures may be necessary to maintain the airway of sleep apnea patients.<ref>{{cite web |url=http://www.nhlbi.nih.gov/health/dci/Diseases/SleepApnea/SleepApnea_LivingWith.html |title=What is Sleep Apnea? |year=2012 |website=National Heart, Lung, and Blood Institute |publisher=National Institutes of Health |access-date=15 February 2013 |url-status=live |archive-url=https://web.archive.org/web/20110828030048/http://www.nhlbi.nih.gov/health/dci/Diseases/SleepApnea/SleepApnea_LivingWith.html |archive-date=28 August 2011}}</ref>

The immediate effects of central sleep apnea on the body depend on how long the failure to breathe endures. At worst, central sleep apnea may cause sudden death. Short of death, drops in blood oxygen may trigger [[seizure]]s, even in the absence of [[epilepsy]]. In people ''with'' epilepsy, the hypoxia caused by apnea may trigger seizures that had previously been well controlled by medications.<ref name="Epilepsy and sleep apnea syndrome"/> In other words, a seizure disorder may become unstable in the presence of sleep apnea. In adults with [[coronary artery disease]], a severe drop in blood oxygen level can cause [[angina]], [[Heart arrhythmia|arrhythmia]]s, or heart attacks ([[myocardial infarction]]). Longstanding recurrent episodes of apnea, over months and years, may cause an increase in carbon dioxide levels that can change the pH of the blood enough to cause a [[respiratory acidosis]].{{medical citation needed|data=February 2024|date=February 2024}}

The costs of untreated sleep apnea reach further than just health issues. It is estimated that in the U.S., the average untreated sleep apnea patient's annual health care costs $1,336 more than an individual without sleep apnea. This may cause $3.4 billion/year in additional medical costs. Whether medical cost savings occur with treatment of sleep apnea remains to be determined.<ref>{{cite journal |last1=Kapur |first1=Vishesh |last2=Blough |first2=David K. |last3=Sandblom |first3=Robert E. |last4=Hert |first4=Richard |last5=de Maine |first5=James B. |last6=Sullivan |first6=Sean D. |last7=Psaty |first7=Bruce M. |title=The Medical Cost of Undiagnosed Sleep Apnea |journal=Sleep |date=September 1999 |volume=22 |issue=6 |pages=749–755 |doi=10.1093/sleep/22.6.749 |pmid=10505820 |doi-access=free }}</ref>

The term "[[Pickwickian syndrome]]" that is sometimes used for the syndrome was coined by the famous early 20th-century physician [[William Osler]], who must have been a reader of [[Charles Dickens]]. The description of Joe, "the fat boy" in Dickens's novel ''[[The Pickwick Papers]]'', is an accurate clinical picture of an adult with obstructive sleep apnea syndrome.<ref>{{cite journal | vauthors = Kryger MH | title = Fat, sleep, and Charles Dickens: literary and medical contributions to the understanding of sleep apnea | journal = Clinics in Chest Medicine | volume = 6 | issue = 4 | pages = 555–62 | date = December 1985 | doi = 10.1016/S0272-5231(21)00394-4 | pmid = 3910333 }}</ref>

The early reports of obstructive sleep apnea in the medical literature described individuals who were very severely affected, often presenting with severe [[hypoxemia]], [[hypercapnia]] and [[congestive heart failure]].{{medical citation needed|data=February 2024|date=February 2024}}

===Treatment===
The management of obstructive sleep apnea was improved with the introduction of [[continuous positive airway pressure]] (CPAP), first described in 1981 by Colin Sullivan and associates in [[Sydney]], Australia.<ref>{{cite journal | vauthors = Sullivan CE, Issa FG, Berthon-Jones M, Eves L | title = Reversal of obstructive sleep apnoea by continuous positive airway pressure applied through the nares | journal = Lancet | volume = 1 | issue = 8225 | pages = 862–5 | date = April 1981 | pmid = 6112294 | doi = 10.1016/S0140-6736(81)92140-1 | s2cid = 25219388 }}</ref> The first models were bulky and noisy, but the design was rapidly improved and by the late 1980s, CPAP was widely adopted. The availability of an effective treatment stimulated an aggressive search for affected individuals and led to the establishment of hundreds of specialized clinics dedicated to the diagnosis and treatment of [[sleep disorders]]. Though many types of sleep problems are recognized, the vast majority of patients attending these centers have sleep-disordered breathing. Sleep apnea awareness day is 18 April in recognition of Colin Sullivan.<ref>{{cite web|last=Sichtermann|first=Lori|title=Industry Recognizes Sleep Apnea Awareness Day 2014|date=19 April 2014|url=http://www.sleepreviewmag.com/2014/04/sleep-apnea-awareness-day-2014/|publisher=Sleep Review|access-date=30 April 2014|url-status=live|archive-url=https://web.archive.org/web/20140430083056/http://www.sleepreviewmag.com/2014/04/sleep-apnea-awareness-day-2014/|archive-date=30 April 2014}}</ref>
