Sleep Medicine
Obstructive Sleep Apnea
Diagnose suspected obstructive sleep apnea with appropriate sleep testing, prioritize symptom relief and blood-pressure control, and match PAP, mandibular advancement, weight management, positional therapy, or selected surgery to anatomy, severity, and treatment tolerance.
Diagnosis
Confirm OSA with sleep testing before selecting therapy
Testing should establish the sleep-breathing disorder and provide a baseline for treatment response.
Order diagnostic sleep testing when the history and examination raise concern for clinically important OSA; the American Academy of Sleep Medicine diagnostic guideline addresses testing strategy for adults. AHA JournalsAHA Journals2025 AHA/ACC/AANP/AAPA/ABC/ACCP/ACPM/AGS/AMA/ ... In patients with cardiovascular disease or hypertension, identify OSA as a potential contributor to elevated blood pressure and symptom burden, but do not treat a screening result as a diagnostic endpoint. AHA Journals+1AHA Journals2025 AHA/ACC/AANP/AAPA/ABC/ACCP/ACPM/AGS/AMA/ ...jacc2026 AHA/ACC/ADA/ASN Guideline for the Prevention ...
Use the diagnostic study to distinguish obstructive events from other sleep-disordered breathing patterns before choosing PAP mode, oral appliance therapy, or an upper-airway intervention. Reassess for alternative explanations of daytime sleepiness, impaired function, or nocturnal symptoms when sleep testing does not establish clinically relevant OSA. AHA Journals+1AHA Journals2025 AHA/ACC/AANP/AAPA/ABC/ACCP/ACPM/AGS/AMA/ ...jacc2026 AHA/ACC/ADA/ASN Guideline for the Prevention ...
Document blood pressure, body weight, sleepiness-related functional risk, and cardiovascular comorbidity at diagnosis because these parameters affect treatment goals. Moderate-to-severe OSA is associated with hypertension, cardiovascular events, and mortality; severe OSA is also associated with increased all-cause mortality.

Initial Treatment
Use PAP as the principal noninvasive treatment and measure adherence
Therapy should target airway obstruction, symptoms, functional impairment, and relevant blood-pressure burden.
Offer positive airway pressure therapy as the principal noninvasive treatment for diagnosed OSA when the patient can use it. PAP effectively treats OSA, while CPAP can eliminate recurrent hypoxia and reduce nocturnal blood pressure and heart rate. AHA Journals+1AHA Journals2025 AHA/ACC/AANP/AAPA/ABC/ACCP/ACPM/AGS/AMA/ ...AHA JournalsSleep Apnea and Cardiovascular Disease | Circulation At initiation, establish a practical adherence plan that addresses mask tolerance, nasal symptoms, pressure comfort, sleep schedule, and device-download review.
At follow-up, assess patient-reported sleepiness, functional improvement, adverse effects, residual device-reported events, and actual nightly use rather than assuming efficacy from prescription alone. The association between hours of CPAP use and improved insulin sensitivity in randomized data supports prioritizing sustained nightly exposure when metabolic outcomes are relevant. jaccjaccSleep Apnea: Types, Mechanisms, and Clinical Cardiovascular Consequences
For hypertension, continue antihypertensive medication rather than substituting CPAP for standard blood-pressure treatment. Weight loss combined with CPAP can reduce BP in adults with overweight or obesity, and some studies show BP reduction with CPAP in resistant hypertension. AHA JournalsAHA Journals2025 AHA/ACC/AANP/AAPA/ABC/ACCP/ACPM/AGS/AMA/ ... Do not represent CPAP as established secondary prevention for cardiovascular events: randomized comparisons of CPAP with usual care have not shown reductions in mortality, cardiovascular events, or kidney events. jaccjacc2026 AHA/ACC/ADA/ASN Guideline for the Prevention ...
Use symptom change, device-use data, and BP trend as separate outcomes; improvement in one does not establish improvement in all three.

Escalate adherence troubleshooting before abandoning PAP when the barrier is interface discomfort, nasal intolerance, or irregular sleep timing; CPAP adherence is clinically consequential.

For patients with overweight or obesity, pair OSA therapy with a structured weight-management intervention rather than presenting PAP as a substitute for weight loss.

Cardiometabolic expectations
Explain the treatment target precisely: CPAP improves OSA control and may improve blood pressure, insulin sensitivity, symptoms, and quality of life, but evidence does not establish that CPAP prevents cardiovascular events in unselected cardiovascular populations.

Therapy Selection
Match alternatives to PAP intolerance, patient preference, anatomy, and severity
Non-PAP therapy is appropriate when it can provide an effective and durable alternative for the individual patient.
Offer a mandibular advancement device to adults with OSA who prefer oral-appliance therapy or cannot tolerate CPAP. ACP recommends mandibular advancement devices as an alternative to CPAP in diagnosed OSA, and professional guidance supports oral appliances for patients who prefer them or are CPAP-intolerant. acpjournals+1acpjournalsManagement of Obstructive Sleep Apnea in AdultsScienceDirectPrediction of oral appliance treatment outcomes in obstructive sleep apnea: A systematic review - ScienceDirect Custom devices fitted by a qualified dentist outperform off-the-shelf appliances and should be physician-prescribed. AHA JournalsAHA JournalsObstructive Sleep Apnea and Cardiovascular Disease
Mandibular advancement devices are most commonly used for mild-to-moderate OSA or when CPAP is not tolerated, although response is not uniform across severity categories. AHA Journals+1AHA JournalsObstructive Sleep Apnea and Cardiovascular DiseaseScienceDirectPrediction of oral appliance treatment outcomes in obstructive sleep apnea: A systematic review - ScienceDirect Reassess symptoms and objective treatment response after device titration; do not infer control from perceived snoring reduction alone. Oral appliances can cause myofascial discomfort and excess salivation, which should prompt dental adjustment rather than automatic discontinuation. AHA JournalsAHA JournalsObstructive Sleep Apnea and Cardiovascular Disease
Use positional therapy when testing and clinical pattern suggest positional OSA and when a positional strategy is acceptable to the patient. Positional OSA occurs even in severe disease, and lateral-position approaches may be particularly relevant when obstruction is tongue-base predominant. BMJ+1BMJConfidential: For Review OnlyBMJ1 / 94 1 May 13th, 2025 2 Dr. Di Wang 3 Clinical Editor, The ... Confirm that the intervention controls the patient’s documented sleep-disordered breathing burden rather than relying solely on subjective improvement.
Recommend weight management for adults with overweight or obesity as a disease-modifying adjunct to airway therapy. Weight loss and lifestyle interventions improve OSA severity, and weight loss combined with CPAP can reduce BP.

Choose a custom mandibular advancement device rather than an over-the-counter appliance when selecting oral-appliance therapy. AHA JournalsAHA JournalsObstructive Sleep Apnea and Cardiovascular Disease
Refer to a qualified dentist for fitting and longitudinal dental assessment of a mandibular advancement device. AHA JournalsAHA JournalsObstructive Sleep Apnea and Cardiovascular Disease
Use a patient’s preference and ability to adhere to therapy as major selection variables; oral appliances may have greater overall adherence than CPAP despite less predictable physiologic efficacy.

Address alcohol and sedative exposure when pharyngeal collapse is a concern; abstinence from alcohol and sedatives is advised because they can predispose to sleep-related pharyngeal collapse. jaccjaccSleep Apnea and Cardiovascular Disease
Escalation
Use anatomic evaluation to select surgery or hypoglossal nerve stimulation
Procedural therapy is generally considered after inadequate response to, or intolerance of, noninvasive treatment.
Refer patients with persistent clinically consequential OSA despite noninvasive therapy, or with treatment-limiting PAP intolerance, for sleep-surgery evaluation when an anatomic target is plausible. Available surgical approaches include nasal septoplasty, adenotonsillectomy, uvulopalatoplasty, and maxillomandibular advancement; multilevel surgery is used when obstruction or collapse occurs at multiple levels. AHA JournalsAHA JournalsObstructive Sleep Apnea and Cardiovascular Disease
Use drug-induced sleep endoscopy and upper-airway assessment to characterize the site and pattern of collapse when planning targeted procedural therapy. Upper-airway collapse on drug-induced sleep endoscopy is relevant to surgical and hypoglossal nerve stimulation selection, and preoperative predictors of hypoglossal nerve stimulation response have been described. BMJ+1BMJConfidential: For Review OnlyBMJ1 / 94 1 May 13th, 2025 2 Dr. Di Wang 3 Clinical Editor, The ...

Consider hypoglossal nerve stimulation as a surgical alternative for selected OSA patients who do not tolerate or respond adequately to other treatment approaches. Selection requires evaluation of upper-airway collapse pattern and individualized discussion of surgical risks, expected efficacy, device management, and alternatives.

Position nasal surgery appropriately: septoplasty may improve PAP delivery rather than serve as stand-alone curative treatment for OSA. AHA JournalsAHA JournalsObstructive Sleep Apnea and Cardiovascular Disease For any airway surgery, counsel that procedures are rarely curative and may be best incorporated into a multimodal plan with objective post-treatment reassessment.

Monitoring
Reassess efficacy after every material change in therapy or risk profile
OSA treatment is durable only when symptoms, adherence, and cardiometabolic goals are reviewed longitudinally.
After PAP, oral-appliance titration, weight loss intervention, positional treatment, or surgery, reassess symptoms, functional safety, treatment tolerance, and objective control of sleep-disordered breathing. This is particularly important when a patient reports improved snoring but retains sleepiness, hypertension, or device intolerance.

Monitor BP separately from OSA symptoms. OSA therapy may improve BP, especially with CPAP in resistant hypertension and with combined CPAP plus weight loss in overweight or obesity, but antihypertensive treatment remains necessary when indicated. AHA JournalsAHA Journals2025 AHA/ACC/AANP/AAPA/ABC/ACCP/ACPM/AGS/AMA/ ... If BP remains resistant despite apparent OSA control, evaluate adherence and continue the broader secondary-hypertension and medication assessment.
Revisit treatment choice when body weight changes, a dental appliance causes adverse effects, PAP use declines, a positional strategy fails, or postoperative symptoms persist. OSA management frequently requires combination therapy—such as weight management plus PAP, or nasal intervention to facilitate PAP—rather than a single permanent intervention.
