Sleep apnea is a prevalent sleep disorder marked by repeated interruptions in breathing during sleep, which can lead to fragmented rest and a range of serious health issues. Traditionally, diagnosing this condition involved spending a night in a sleep clinic for a detailed polysomnography test.
This process, while thorough, can be inconvenient and uncomfortable for many. Fortunately, advancements in medical technology have led to the development of home sleep apnea tests (HSATs), providing a more accessible and less intrusive alternative.
These tests allow individuals to monitor their sleep patterns from the comfort of their own home, potentially simplifying the diagnostic process.
This guide will explore everything you need to know about home sleep apnea tests, including their functionality, benefits, limitations, and key considerations for those contemplating their use.
Understanding Sleep Apnea
What is Sleep Apnea?
Sleep apnea is a pervasive and potentially serious sleep disorder characterized by repeated interruptions in breathing during sleep. These pauses in breathing can last from a few seconds to minutes and can occur multiple times throughout the night, disrupting normal sleep patterns and leading to a host of health issues.
The most prevalent form of sleep apnea is obstructive sleep apnea (OSA), which occurs when the throat muscles relax excessively, causing a temporary blockage of the airway.
Another form is central sleep apnea, where the brain fails to send the appropriate signals to the muscles responsible for breathing.
There is also complex sleep apnea syndrome, a condition where both obstructive and central sleep apneas are present. Understanding the different types of sleep apnea is crucial for recognizing symptoms and seeking appropriate treatment to improve overall health and quality of life.
Symptoms of Sleep Apnea
Sleep apnea can manifest through a variety of symptoms, some more noticeable than others. Recognizing these symptoms is crucial for seeking appropriate diagnosis and treatment. Here are the key symptoms often associated with sleep apnea:
Loud Snoring
One of the most common and noticeable symptoms of sleep apnea, particularly obstructive sleep apnea (OSA), is loud snoring. This snoring is typically loud enough to disturb the sleep of others and is characterized by pauses and choking or gasping sounds as breathing resumes.
While not everyone who snores has sleep apnea, snoring accompanied by other symptoms warrants further investigation.
Excessive Daytime Sleepiness
Individuals with sleep apnea often experience excessive daytime sleepiness, regardless of how much time they spend in bed. This symptom is due to the fragmented sleep caused by repeated interruptions in breathing.
This persistent tiredness can significantly impact daily activities, reduce productivity, and increase the risk of accidents, especially while driving or operating machinery.
Waking Up with a Dry Mouth or Sore Throat
Many people with sleep apnea wake up with a dry mouth or sore throat.
This is because breathing through the mouth, rather than the nose, often occurs when the airway is blocked. The mouth becomes dry overnight, leading to discomfort upon waking.
Difficulty Concentrating
Cognitive impairment is another common symptom. People with sleep apnea may struggle with concentration, memory, and decision-making.
These cognitive issues arise due to the lack of restorative sleep, which is essential for brain function. Over time, chronic sleep deprivation can exacerbate these problems.
Irritability or Mood Swings
Sleep apnea can significantly affect mood. The chronic fatigue and disrupted sleep patterns associated with this condition can lead to irritability, mood swings, and even depression.
Addressing sleep apnea can often result in noticeable improvements in mood and emotional stability.
Morning Headaches
Frequent morning headaches are a less recognized but common symptom of sleep apnea.
These headaches are usually tension-type and are thought to be caused by fluctuating oxygen and carbon dioxide levels in the blood due to interrupted breathing during sleep.
Difficulty Staying Asleep
Also known as insomnia, difficulty staying asleep can be a result of the frequent awakenings caused by breathing interruptions. Individuals may wake up multiple times during the night, often without realizing the cause, leading to non-refreshing sleep.
Recognizing these symptoms is a crucial step toward diagnosing and treating sleep apnea. If you or a loved one are experiencing several of these symptoms, it is important to consult a healthcare provider or sleep specialist.
Early diagnosis and treatment can improve sleep quality and overall health, reducing the risk of associated complications such as cardiovascular disease, diabetes, and daytime fatigue.
Risks and Complications
Untreated sleep apnea can lead to a multitude of serious health complications, significantly impacting both short-term and long-term well-being. The continuous interruptions in breathing disrupt the sleep cycle, preventing restorative sleep and leading to various physiological stresses.
High Blood Pressure
One of the most common complications associated with untreated sleep apnea is high blood pressure (hypertension). The frequent drops in blood oxygen levels that occur with sleep apnea episodes trigger the release of stress hormones, which in turn raise blood pressure.
This increased pressure can persist during the day and night, leading to chronic hypertension. Over time, high blood pressure damages the walls of the blood vessels, increasing the risk of cardiovascular diseases.
Heart Disease
Sleep apnea is closely linked to an increased risk of heart disease. The repeated interruptions in breathing and the resultant low oxygen levels put a strain on the heart.
This can lead to a range of heart-related problems, including arrhythmias (irregular heartbeats), heart attacks, and heart failure. The stress placed on the cardiovascular system by sleep apnea exacerbates the progression of these conditions.
Stroke
Individuals with sleep apnea are at a heightened risk of stroke. The mechanisms that link sleep apnea to stroke are multifaceted, involving the cumulative effects of high blood pressure, heart disease, and the direct impacts of repeated oxygen deprivation on the brain.
Stroke risk is particularly elevated in people who experience severe sleep apnea.
Type 2 Diabetes
There is a significant association between sleep apnea and type 2 diabetes. The intermittent hypoxia (low oxygen levels) and sleep fragmentation caused by sleep apnea affect the body’s glucose metabolism.
Insulin resistance, a precursor to diabetes, is commonly observed in individuals with sleep apnea. Effective management of sleep apnea can help improve blood sugar control and reduce the risk of developing diabetes.
Weight Gain
Sleep apnea and weight gain have a bidirectional relationship. Obesity is a significant risk factor for sleep apnea, and sleep apnea can contribute to weight gain. Poor sleep quality affects hormones that regulate hunger and appetite, often leading to increased caloric intake and reduced energy expenditure.
This cycle can exacerbate both conditions, making management more challenging.
Liver Problems
Untreated sleep apnea can lead to liver problems, including nonalcoholic fatty liver disease (NAFLD).
The chronic intermittent hypoxia associated with sleep apnea can promote liver inflammation and fibrosis, contributing to the progression of liver disease.
Increased Risk of Accidents
The excessive daytime sleepiness resulting from sleep apnea increases the risk of accidents, particularly motor vehicle accidents. Individuals with untreated sleep apnea are more likely to experience lapses in attention, slower reaction times, and a higher propensity for falling asleep while driving.
This heightened accident risk extends to workplace accidents and other situations requiring alertness and concentration.
In conclusion, the health complications associated with untreated sleep apnea are extensive and serious. Proper diagnosis and management of sleep apnea are crucial in mitigating these risks and improving overall health outcomes.
Traditional Sleep Studies vs. Home Sleep Apnea Tests
Diagnosing sleep apnea has traditionally required an overnight stay in a sleep clinic for a polysomnography test, where a range of physiological parameters are monitored to provide a comprehensive assessment of sleep patterns and disruptions.
However, advancements in medical technology have introduced home sleep apnea tests (HSATs) as a convenient alternative. These tests allow individuals to monitor their sleep in the comfort of their own home, offering a more accessible and often cost-effective option.
This section will explore the differences between traditional sleep studies and home sleep apnea tests, highlighting their respective benefits and limitations.
Polysomnography
Polysomnography (PSG) is a comprehensive and detailed sleep study conducted in a specialized sleep clinic. This diagnostic tool is considered the gold standard for diagnosing sleep disorders, including sleep apnea, narcolepsy, restless leg syndrome, and other conditions that affect sleep quality.
During a polysomnography test, a variety of physiological parameters are monitored throughout the night to provide an in-depth analysis of a patient’s sleep patterns and disturbances.
Key Parameters Monitored in Polysomnography
Brain Activity (EEG)
Electroencephalography (EEG) records electrical activity in the brain, which is crucial for identifying different stages of sleep, including rapid eye movement (REM) and non-REM sleep. EEG data helps in understanding the sleep architecture and diagnosing disorders that disrupt normal sleep cycles.
Eye Movements (EOG)
Electrooculography (EOG) measures eye movements, particularly useful in detecting REM sleep, where rapid eye movements are a defining characteristic. Tracking eye movements helps in determining transitions between sleep stages and identifying any abnormalities in sleep patterns.
Muscle Activity (EMG)
Electromyography (EMG) records muscle activity, particularly in the chin and legs. This data is essential for diagnosing conditions like REM sleep behavior disorder (RBD), where individuals may act out dreams, and periodic limb movement disorder (PLMD), characterized by involuntary limb movements during sleep.
Heart Rate (ECG)
Electrocardiography (ECG) monitors heart rate and rhythm. Sleep disorders, especially sleep apnea, can cause significant changes in heart rate and may lead to arrhythmias. Continuous monitoring of the heart helps in identifying cardiovascular complications associated with sleep disturbances.
Oxygen Levels (Pulse Oximetry)
Pulse oximetry measures blood oxygen saturation levels. Frequent drops in oxygen levels during sleep are indicative of sleep apnea, where breathing interruptions reduce oxygen intake. Monitoring oxygen saturation is crucial for diagnosing and assessing the severity of sleep apnea.
Respiratory Effort
Sensors placed around the chest and abdomen measure the effort required to breathe. In cases of obstructive sleep apnea, these sensors detect the increased effort needed to overcome the airway obstruction. This data helps differentiate between obstructive and central sleep apnea.
Airflow
Airflow sensors placed near the nose and mouth measure the volume and rate of air entering and exiting the lungs. Disruptions in airflow patterns are a primary indicator of sleep apnea and other respiratory disorders affecting sleep.
Comprehensive Analysis
Polysomnography provides a detailed picture of an individual’s sleep architecture, which includes the distribution and duration of sleep stages throughout the night. By analyzing the collected data, sleep specialists can identify specific sleep disorders and their underlying causes.
The comprehensive nature of PSG makes it an invaluable tool for developing effective treatment plans tailored to the patient’s needs.
In summary, polysomnography is an essential and comprehensive diagnostic procedure that captures a wide array of physiological data during sleep.
It remains the benchmark for diagnosing complex sleep disorders, providing critical insights into the mechanisms disrupting sleep and guiding targeted therapeutic interventions.
Home Sleep Apnea Tests
Home sleep apnea tests (HSATs) offer a convenient and increasingly popular alternative to traditional sleep studies conducted in clinical settings. These tests are designed to be used in the comfort of your own home, providing a more accessible option for diagnosing sleep apnea.
While HSATs are less comprehensive than polysomnography (PSG), they focus on key physiological parameters relevant to identifying sleep apnea.
Key Parameters Monitored in Home Sleep Apnea Tests
Airflow
HSATs typically include sensors placed near the nose and mouth to measure airflow. These sensors detect the volume and rate of air entering and exiting the lungs. By monitoring airflow, HSATs can identify interruptions in breathing that are characteristic of sleep apnea. This parameter helps in detecting both the frequency and severity of apneic events during the night.
Respiratory Effort
Respiratory effort belts are often placed around the chest and abdomen to measure the effort involved in breathing. These belts detect changes in thoracic and abdominal movement, providing data on how hard the body is working to breathe. This measurement is crucial for distinguishing between obstructive sleep apnea (OSA), where there is increased effort due to airway obstruction, and central sleep apnea (CSA), where there is a lack of effort due to a failure in the brain’s signaling.
Blood Oxygen Levels
Pulse oximetry is used to measure blood oxygen saturation levels. This sensor is usually attached to a finger or earlobe. Drops in blood oxygen levels are a significant indicator of sleep apnea, as apneic events cause temporary reductions in oxygen intake. Monitoring blood oxygen levels helps assess the severity of sleep apnea and its potential impact on overall health.
Heart Rate
Some HSATs include a sensor to monitor heart rate, often integrated with the pulse oximeter. Changes in heart rate can be associated with apneic events and other disturbances in sleep. Monitoring heart rate provides additional data that can help in evaluating the cardiovascular effects of sleep apnea.
Advantages and Limitations

They are particularly useful for patients needing a thorough evaluation of their sleep-related issues while maintaining the comfort and familiarity of their home environment.
Type III HSAT
Type III home sleep apnea tests (HSATs) are often referred to as “simplified” devices due to their basic design and limited measurement capabilities.
Unlike Type I and Type II HSATs, which offer a more comprehensive assessment by monitoring multiple physiological parameters, Type III devices typically focus on just a few key metrics.
The most common parameters measured by Type III HSATs include airflow and blood oxygen levels.
Airflow sensors are placed near the nose or mouth to detect disruptions in breathing, while pulse oximeters measure oxygen saturation in the blood. These parameters are crucial for identifying the presence of sleep apnea and evaluating its severity.
However, the limited scope of Type III HSATs can affect their diagnostic accuracy.
By concentrating primarily on airflow and oxygen levels, these devices may miss other important indicators of sleep apnea, such as respiratory effort and heart rate variability.
This simplified approach may lead to a less detailed understanding of the sleep disturbances and can potentially result in false negatives or incomplete diagnoses, especially in complex cases or when other sleep disorders are present.
Despite these limitations, Type III HSATs can still be useful for initial screenings or for patients with a clear clinical presentation of sleep apnea.
They offer a more affordable and convenient option compared to more comprehensive tests, making them a viable choice for many individuals seeking to understand their sleep health.
Type IV HSAT
Type IV Home Sleep Apnea Tests (HSATs) are the most basic and often the most affordable option available for sleep apnea diagnosis. These devices are designed to monitor a minimal number of physiological parameters, typically focusing on just one or two critical metrics.
The most common parameters measured by Type IV HSATs include blood oxygen saturation and airflow.
Blood oxygen saturation is usually monitored through a pulse oximeter attached to a finger or earlobe.
This sensor detects drops in oxygen levels that occur during apneic events. Airflow is often measured through a nasal cannula or a simple airflow sensor placed near the nose and mouth. These two parameters provide basic but essential information about breathing disruptions.
While Type IV HSATs offer a cost-effective solution for sleep apnea testing, their limited scope means they may not capture all the nuances of the disorder.
For instance, these tests generally do not monitor respiratory effort, which is crucial for distinguishing between obstructive and central sleep apnea. As a result, Type IV HSATs are less comprehensive and may not provide a complete picture of the severity or type of sleep apnea.
Due to their limited accuracy, Type IV HSATs are usually recommended for patients with straightforward symptoms or as a preliminary screening tool. For a more detailed evaluation, especially in complex or severe cases, more advanced HSAT types or in-lab polysomnography may be necessary.

Recognizing these limitations will help you and your healthcare provider determine the best approach for evaluating and managing your sleep health.
Limited Data
One of the primary limitations of home sleep apnea tests (HSATs) is the relatively limited scope of data they provide compared to traditional polysomnography. While HSATs focus on key parameters such as airflow, respiratory effort, oxygen levels, and sometimes heart rate, they generally do not monitor the full range of physiological factors captured by polysomnography.
Polysomnography (PSG) provides a comprehensive assessment by measuring multiple parameters, including brain activity (EEG), eye movements (EOG), muscle activity (EMG), and more.
This extensive monitoring allows for a detailed analysis of sleep architecture and the identification of various sleep disorders beyond sleep apnea, such as restless leg syndrome or narcolepsy.
In contrast, HSATs often concentrate on only the most essential indicators of sleep apnea, which may not be sufficient for diagnosing complex or atypical cases.
For instance, HSATs typically do not measure brain waves or detailed muscle activity, which can be critical for distinguishing between different types of sleep apnea or for identifying other sleep-related conditions.
This limitation can be particularly significant for patients with mixed or complex forms of sleep apnea, where a more nuanced understanding of the sleep disturbances is required.
Therefore, while HSATs are effective for diagnosing straightforward cases of sleep apnea, they may fall short in providing a complete diagnostic picture, especially for individuals with more complicated sleep disorders.
In such cases, a follow-up polysomnography or further diagnostic testing may be necessary to obtain a comprehensive evaluation.
Accuracy Concerns
The accuracy of home sleep apnea tests (HSATs) is a significant consideration, as it can impact the reliability of the diagnosis and the effectiveness of subsequent treatment. Several factors influence the accuracy of HSATs, primarily the type of device used and the quality of its setup.
One major concern is that HSATs typically monitor a limited number of physiological parameters compared to comprehensive polysomnography. While they often track airflow, respiratory effort, oxygen levels, and heart rate, they may not capture all relevant data needed to detect every instance of sleep apnea.
This limitation can result in false negatives, where sleep apnea episodes are missed despite their presence.
The accuracy of HSATs also heavily depends on proper setup and usage. Incorrect placement of sensors, such as the nasal cannula or pulse oximeter, can lead to inaccurate readings. For example, if the airflow sensor is not positioned correctly, it may not detect all interruptions in breathing.
Similarly, if the pulse oximeter is not securely attached, it might fail to measure accurate oxygen levels, leading to incomplete data.
Additionally, some HSATs are designed for basic screening and may not be sensitive enough to detect more subtle or complex forms of sleep apnea. This limitation can be particularly problematic for patients with atypical symptoms or those who require a detailed analysis of their sleep patterns.
Overall, while HSATs provide valuable insights and a convenient diagnostic option, their accuracy concerns highlight the importance of carefully considering their limitations and, when necessary, complementing them with more comprehensive diagnostic methods.
Inability to Diagnose Other Sleep Disorders
Home sleep apnea tests (HSATs) are specifically designed to identify and evaluate sleep apnea by monitoring key parameters such as airflow, respiratory effort, and oxygen levels. However, their focused scope means they are not equipped to diagnose other sleep disorders or underlying conditions.
HSATs typically measure basic indicators related to sleep apnea, such as interruptions in breathing and drops in blood oxygen levels. They do not provide a comprehensive analysis of sleep architecture, which is crucial for diagnosing a range of other sleep disorders.
For example, conditions like restless leg syndrome, narcolepsy, and REM sleep behavior disorder require a detailed assessment of sleep stages and muscle activity that HSATs cannot provide.
Restless leg syndrome, characterized by uncomfortable sensations and an irresistible urge to move the legs during periods of rest, often necessitates an evaluation of limb movements that HSATs do not monitor.
Narcolepsy, marked by excessive daytime sleepiness and sudden sleep attacks, requires a thorough assessment of sleep patterns and brain activity that goes beyond the capabilities of HSATs.
Additionally, some individuals with sleep apnea may have coexisting conditions or complex cases that need more detailed examination. In such situations, polysomnography (PSG) or other specialized tests may be required to accurately diagnose and differentiate between multiple sleep disorders.
In summary, while HSATs are effective for diagnosing sleep apnea, their limitations in detecting other sleep disorders mean that additional testing might be necessary if you experience symptoms beyond those related to sleep apnea.

Continuous Positive Airway Pressure (CPAP)
Continuous Positive Airway Pressure (CPAP) therapy is widely recognized as the most effective and commonly used treatment for obstructive sleep apnea (OSA).
This therapy involves the use of a CPAP machine, which delivers a continuous stream of air through a mask worn over the nose or mouth during sleep. The purpose of the air pressure is to keep the airway open, preventing the collapse or blockage that characterizes obstructive sleep apnea.
How CPAP Therapy Works
- Machine Components:
The CPAP system consists of a machine, a hose, and a mask. The machine generates a continuous flow of air, which travels through the hose to the mask. The mask, which can be a nasal mask, full-face mask, or nasal pillows, ensures that the air pressure is directed into the airway. - Airway Management:
By maintaining a steady airflow, the CPAP machine helps to keep the upper airway open throughout the night. This prevents the frequent pauses in breathing and reduced oxygen levels associated with sleep apnea. The continuous air pressure acts as a pneumatic splint, effectively reducing or eliminating apneic events. - Adjustable Settings:
CPAP machines can be adjusted to deliver the optimal pressure required for each individual. During the initial setup, a sleep study or titration test is usually conducted to determine the appropriate pressure settings. The machine may also have features to adjust pressure based on changes in your breathing patterns throughout the night.
Benefits of CPAP Therapy
- Improved Sleep Quality: CPAP therapy significantly reduces interruptions in sleep, leading to more restful and uninterrupted sleep.
- Enhanced Daytime Functioning: By improving sleep quality, CPAP helps reduce daytime sleepiness and enhances overall cognitive and physical performance.
- Long-Term Health Benefits: Effective management of sleep apnea through CPAP therapy can reduce the risk of associated health issues, such as high blood pressure, heart disease, and stroke.
Challenges and Considerations
While CPAP therapy is highly effective, some users may experience challenges such as discomfort with the mask, difficulty adjusting to the airflow, or feeling claustrophobic. Regular follow-up with a healthcare provider can help address these issues and optimize the therapy for the best results.
Overall, CPAP therapy remains a cornerstone in the management of obstructive sleep apnea, providing significant relief and improving quality of life for many individuals.
Lifestyle Changes
Implementing lifestyle changes can significantly improve sleep apnea symptoms and overall health. These adjustments are often recommended as initial or complementary strategies alongside other treatments. Here are some key lifestyle changes that can help manage sleep apnea:
Weight Loss
Excess weight, particularly around the neck and abdomen, can contribute to airway obstruction and worsen sleep apnea. Losing weight through a balanced diet and regular exercise can reduce the severity of the condition or, in some cases, even resolve it. Even modest weight loss can lead to substantial improvements in sleep quality and breathing patterns.
Avoiding Alcohol
Alcohol relaxes the muscles of the throat, which can increase the likelihood of airway collapse during sleep. Avoiding alcohol, especially in the hours leading up to bedtime, can help prevent these muscle relaxations and reduce the frequency and severity of apneic events.
Quitting Smoking
Smoking irritates the airways and contributes to inflammation and swelling in the respiratory tract, which can exacerbate sleep apnea. Quitting smoking not only improves overall respiratory health but also helps reduce airway inflammation, making it easier to breathe during sleep.
Positional Therapy
For some individuals, sleep apnea is more pronounced when sleeping on the back. Sleeping on your side can alleviate this problem by preventing the tongue and soft tissues from obstructing the airway. Special pillows or devices are available to help maintain a side-sleeping position.
Improving Sleep Hygiene
Establishing a regular sleep schedule and creating a comfortable sleep environment can enhance sleep quality. Avoiding large meals, caffeine, and electronic screens before bedtime can also improve sleep patterns and support overall health.
Incorporating these lifestyle changes can be an effective strategy in managing sleep apnea. However, it’s important to consult with a healthcare provider to ensure these changes are appropriately tailored to your condition and to determine if additional treatments are necessary.
Oral Appliances
Oral appliances, also known as dental devices or mandibular advancement devices, are a treatment option designed to manage sleep apnea by mechanically adjusting the position of the jaw and tongue. These devices are typically used for individuals with mild to moderate obstructive sleep apnea (OSA) and offer a non-invasive alternative to continuous positive airway pressure (CPAP) therapy.
Functionality
Oral appliances work by repositioning the lower jaw (mandible) and, in some cases, the tongue forward. This repositioning helps to keep the airway open during sleep by preventing the collapse of the soft tissues in the throat. By maintaining an open airway, these devices can reduce or eliminate the apneas (pauses in breathing) and hypopneas (shallow breathing) associated with sleep apnea.
Types
There are several types of oral appliances, including:
- Mandibular Advancement Devices (MADs): These are the most common type and work by moving the lower jaw forward. This forward positioning helps to prevent the airway from collapsing during sleep.
- Tongue Retaining Devices (TRDs): These devices hold the tongue in a forward position to prevent it from blocking the airway. They are less commonly used but can be effective for some individuals.
Benefits
- Comfort and Convenience: Oral appliances are generally more comfortable and easier to use than CPAP machines. They are smaller, portable, and do not require a power source.
- Improved Compliance: Many patients find them easier to tolerate and more likely to use consistently compared to CPAP.
Limitations
- Effectiveness: Oral appliances are usually effective for mild to moderate OSA but may not be suitable for severe cases.
- Adjustment Period: It may take some time for users to get used to wearing the device, and adjustments may be needed to achieve optimal comfort and effectiveness.

Uvulopalatopharyngoplasty (UPPP)
One of the most common surgical procedures for sleep apnea is uvulopalatopharyngoplasty (UPPP). This surgery involves removing excess tissue from the throat, including the uvula (the small, dangling tissue at the back of the throat), the soft palate, and sometimes the tonsils and adenoids. The goal is to widen the airway and reduce the likelihood of it becoming obstructed during sleep.
Genioglossus Advancement (GA)
Genioglossus advancement is a procedure that repositions the tongue muscle attachment to prevent it from collapsing backward and obstructing the airway. This surgery involves moving the attachment of the genioglossus muscle, which helps keep the airway open, forward to enlarge the airway space.
Maxillomandibular Advancement (MMA)
Maxillomandibular advancement involves repositioning the upper (maxilla) and lower (mandible) jaw to enlarge the airway. This surgery is particularly useful for individuals with severe obstructive sleep apnea caused by anatomical issues with the jaw structure. It can significantly improve airway patency and reduce apneic events.
Hypoglossal Nerve Stimulation
This newer surgical approach involves implanting a device that stimulates the hypoglossal nerve, which controls tongue movement. The stimulation helps prevent the tongue from collapsing into the airway during sleep. It is typically considered for patients who are unable to tolerate CPAP therapy and have moderate to severe obstructive sleep apnea.
Inspire Therapy
Inspire therapy is a specific type of hypoglossal nerve stimulation that involves a surgically implanted device that monitors breathing patterns and provides stimulation to keep the airway open during sleep.
Surgical intervention for sleep apnea is usually considered a last resort, given its invasiveness and potential risks.
