Diagnosis and treatment depend on the type of sleep apnea, severity, symptoms, other medical conditions, and individual circumstances. Common approaches include positive airway pressure therapy, oral appliances, lifestyle measures, and, in selected situations, surgical or other therapies.

Context

Sleep apnea can affect sleep quality and daytime functioning. Symptoms may include loud snoring, witnessed pauses in breathing, gasping during sleep, morning headaches, and excessive daytime sleepiness.

A healthcare professional may evaluate symptoms, medical history, risk factors, and sleep patterns before recommending diagnostic testing.

Common Types of Sleep Apnea

The appropriate diagnostic and treatment approach depends on the specific type and underlying factors.

Diagnostic Testing

A sleep evaluation may include:

• Medical and sleep history

• Physical examination

• Sleep diary

• Home sleep apnea testing

• Overnight polysomnography

• Additional testing when another medical condition may contribute

For adults suspected of having obstructive sleep apnea, the American Academy of Sleep Medicine recommends polysomnography or a technically adequate home sleep apnea test in appropriate uncomplicated patients.

Polysomnography records information such as brain activity, heart rate, breathing, oxygen levels, and movements during sleep.

Sleep Testing Overview

A questionnaire or prediction tool alone should not be used to diagnose obstructive sleep apnea in adults without appropriate objective testing.

Importance

Identifying sleep apnea matters because untreated sleep-disordered breathing can affect sleep quality, concentration, daytime alertness, and overall health. NHLBI notes that untreated sleep apnea is associated with serious health problems, including increased risks involving cardiovascular health.

Sleep apnea management may help address:

• Breathing interruptions during sleep

• Daytime sleepiness

• Snoring

• Poor sleep quality

• Reduced daytime alertness

• Certain cardiovascular risks

• Sleep-related breathing complications

CPAP Therapy

Continuous positive airway pressure, commonly called CPAP, uses a machine to provide air pressure through a mask to help keep the airway open during sleep. It is one of the most common treatments for sleep apnea.

A CPAP system generally includes:

• CPAP machine

• Mask

• Tubing

• Airflow motor

• Optional humidification system

Treatment settings should be determined and adjusted according to clinical guidance rather than changed independently.

Other Positive Airway Pressure Options

Depending on the situation, clinicians may consider:

• CPAP

• APAP

• BPAP

• Other specialized positive-airway-pressure approaches

APAP automatically adjusts pressure during sleep, while BPAP provides different pressure levels during inhalation and exhalation.

Treatment Options

Sleep apnea treatment can involve several approaches.

Positive airway pressure: CPAP and related devices are commonly used to maintain airway openness during sleep.

Oral appliances: Certain oral devices reposition the jaw or tongue to help prevent airway blockage in appropriate patients.

Lifestyle measures: Depending on the individual, clinicians may discuss regular physical activity, healthy sleep habits, weight management when appropriate, limiting alcohol, avoiding smoking, and sleeping positions.

Surgical treatment: Selected patients may be evaluated for procedures addressing anatomical contributors to airway obstruction. Options can include tonsil surgery, upper-airway procedures, jaw advancement, or other interventions.

Recent Updates

During 2025 and 2026, sleep medicine guidance continued to evolve, particularly around central sleep apnea and management of patients with sleep apnea in healthcare settings.

2025 Central Sleep Apnea Guideline

On December 1, 2025, the American Academy of Sleep Medicine published a clinical practice guideline addressing treatment of central sleep apnea in adults. The guideline includes conditional recommendations for therapies such as CPAP, bilevel positive airway pressure with a backup rate, adaptive servo-ventilation, and low-flow oxygen in specific clinical circumstances.

The guideline emphasizes that central sleep apnea treatment should consider the patient's clinical characteristics, underlying conditions, and sleep-study findings rather than focusing only on eliminating breathing events.

Hospital-Based Sleep Apnea Management

A separate AASM guideline published in December 2025 addressed evaluation and management of obstructive sleep apnea among adults receiving hospital-based medical care. It includes recommendations concerning sleep-medicine consultation and planning for diagnosis and management after discharge.

Diagnostic Testing

Home sleep apnea testing remains an option for selected uncomplicated adults at increased risk for moderate-to-severe obstructive sleep apnea, while polysomnography is preferred in several situations involving significant medical or respiratory conditions.

Laws or Policies

Sleep apnea diagnosis and treatment in the United States can involve healthcare regulations, medical-device requirements, insurance policies, professional practice standards, and patient privacy rules.

Medical Device Regulation

CPAP, APAP, BPAP, and related equipment are medical devices. Their prescription, setup, maintenance, and monitoring can involve healthcare professionals, medical-device providers, and insurance requirements.

Patients should follow the instructions provided by their healthcare team and the device manufacturer.

Insurance Coverage

Coverage for sleep studies, PAP equipment, oral appliances, and related care varies according to the insurer, health plan, eligibility requirements, and medical documentation.

NHLBI notes that when CPAP is prescribed, insurance may work with a medical-device company to provide equipment and may review device-use information.

Patient Privacy

Sleep-related medical information is protected under applicable healthcare privacy requirements. Organizations handling protected health information should implement appropriate safeguards for access, storage, transmission, and documentation.

Tools and Resources

People managing suspected or diagnosed sleep apnea may use several resources to organize information and communicate with healthcare professionals.

Helpful resources include:

• Sleep diaries

• Sleep symptom records

• Home sleep testing equipment when clinically ordered

• CPAP compliance data

• PAP device manuals

• Mask-fitting resources

• Sleep-medicine clinics

• Sleep-study centers

• Medical records

• Treatment follow-up schedules

• Sleep-health educational resources

Sleep Apnea Preparation Checklist

Before a sleep evaluation, individuals may want to record:

• Typical bedtime

• Wake-up time

• Nighttime awakenings

• Snoring

• Observed breathing pauses

• Morning symptoms

• Daytime sleepiness

• Current medications

• Relevant medical conditions

• Previous sleep testing

• Current sleep-treatment equipment

Keeping accurate information can help clinicians understand sleep patterns and treatment concerns.

Treatment Management Overview

Frequently Asked Questions

What is sleep apnea?

Sleep apnea is a sleep-related breathing disorder involving repeated interruptions or reductions in breathing during sleep. Obstructive and central sleep apnea are two major forms.

How is sleep apnea diagnosed?

Diagnosis generally involves a clinical sleep evaluation followed by objective testing when appropriate. Depending on the patient, this may involve a home sleep apnea test or overnight polysomnography.

Is CPAP the only treatment for sleep apnea?

No. Treatment options can include CPAP or other PAP therapies, oral appliances, lifestyle measures, and selected surgical or other treatments. The appropriate approach depends on the type and circumstances of the sleep apnea.

What is the difference between CPAP and APAP?

CPAP provides continuous positive airway pressure, while APAP can automatically adjust pressure during sleep. A healthcare professional can determine which approach is appropriate.

Can central sleep apnea be treated with CPAP?

CPAP may be considered for certain forms of central sleep apnea. The 2025 AASM guideline provides conditional recommendations for CPAP in several CSA categories, while other therapies may be appropriate depending on the underlying cause and clinical circumstances.

Conclusion

Sleep apnea treatment begins with appropriate evaluation and diagnosis. Sleep studies, CPAP therapy, APAP, BPAP, oral appliances, lifestyle measures, and selected procedures may all have roles depending on the type of sleep apnea and individual circumstances.

Recent guidance published in 2025 has expanded recommendations for central sleep apnea and hospital-based obstructive sleep apnea management, while established diagnostic guidance continues to support objective testing rather than diagnosis based solely on symptoms or questionnaires.
