What Is the Difference Between CPAP and BiPAP?

Continuous positive airway pressure (CPAP) and bilevel positive airway pressure (BiPAP or VPAP) are both types of non-invasive mechanical ventilation devices used to treat obstructive sleep apnea (OSA) and other respiratory disorders. While both systems share the goal of improving airflow during sleep and preventing interruptions in breathing, they function differently, and their applications are tailored to specific types of conditions or severity levels. Understanding the differences between CPAP and BiPAP is essential for both healthcare providers and patients to ensure that the most suitable treatment is chosen for a given respiratory issue.

Understanding CPAP (Continuous Positive Airway Pressure)

CPAP therapy is the most widely prescribed treatment for obstructive sleep apnea, a condition where the airway becomes blocked or collapses during sleep, causing breathing to repeatedly stop and start. The CPAP device works by delivering a constant stream of air through a mask that covers the nose or nose and mouth. This constant airflow acts as a "splint" for the airway, preventing it from collapsing and ensuring that the individual maintains normal breathing throughout the night. The pressure level remains constant during both inhalation and exhalation.

The CPAP machine consists of a motor that generates airflow through a hose connected to a mask, which is typically worn over the nose, although full-face masks that cover both nose and mouth are also an option for patients who may not breathe well through their nose. This steady flow of air keeps the upper airway open and prevents the episodes of apnea (complete airway blockage) or hypopnea (partial airway blockages) that lead to the symptoms of obstructive sleep apnea, such as daytime sleepiness and fatigue, loud snoring, peeing at night, bruxism (clenching or grinding of teeth), and frequent waking during the night. CPAP is effective in treating mild, moderate, and severe obstructive sleep apnea.

Understanding BiPAP (Bilevel Positive Airway Pressure)

On the other hand, BiPAP, or bilevel positive airway pressure, provides two distinct levels of pressure: a higher pressure during inhalation (known as IPAP, or inspiratory positive airway pressure) and a lower pressure during exhalation (EPAP, or expiratory positive airway pressure). This dual pressure system allows BiPAP to offer more flexibility compared to CPAP. While CPAP maintains a consistent airflow throughout the night, BiPAP automatically adjusts its pressure based on whether the patient is inhaling or exhaling. The higher pressure during inhalation helps ensure that the airway remains open, while the lower pressure during exhalation makes it easier for the patient to breathe out. This can be particularly helpful for individuals who find it difficult to exhale against the constant pressure of a CPAP device, especially at higher settings.

BiPAP machines are commonly prescribed for patients with more complex or severe respiratory conditions. In addition to being used for obstructive sleep apnea, BiPAP is frequently employed in treating central sleep apnea, a condition where the brain fails to send proper signals to the muscles that control breathing. It is also beneficial for patients with chronic respiratory diseases, such as chronic obstructive pulmonary disease (COPD), where the ability to breathe out easily is crucial for effective treatment. The ability to lower the pressure during exhalation is particularly valuable for these patients, as it reduces the work of breathing, making it less effortful to expel air from the lungs.

Key Differences Between CPAP and BiPAP

One of the key differences between CPAP and BiPAP is the level of comfort they provide to the user. CPAP machines, due to their continuous airflow, may be uncomfortable for some patients, especially when they exhale. The constant pressure may make exhalation feel as though the patient is pushing against a continuous force, which can be tiring or stressful. Over time, this discomfort may lead to non-compliance with therapy, as patients may find it challenging to adjust to the sensation of forced exhalation. Although newer CPAP models have introduced features like pressure relief during exhalation (called expiratory pressure relief or EPR), these devices still operate with a single pressure setting that remains constant throughout the night.

BiPAP machines, in contrast, tend to be more comfortable for many patients because the pressure during exhalation is lower than the pressure during inhalation. This allows the patient to breathe out with less resistance, making the process feel more natural. For patients who find it difficult to tolerate the continuous pressure of a CPAP machine, BiPAP can provide a more tolerable and personalized experience. This dual pressure system also allows BiPAP machines to be adjusted in a way that is more specific to the patient’s needs, such as the severity of their sleep apnea or other respiratory conditions. Additionally, some BiPAP devices offer backup respiratory rates, which ensure that the machine provides support if the patient’s breathing becomes too irregular or slow, further enhancing comfort and support.

Indications and Use Cases

Another area where CPAP and BiPAP differ is in their indications for use. CPAP is most commonly prescribed for obstructive sleep apnea, which is characterized by physical blockages in the airway, such as the collapse of throat muscles or the tongue falling backward during sleep. CPAP is highly effective for obstructive sleep apnea, where the primary concern is keeping the airway open with a constant flow of air. However, for those requiring higher pressures, or for patients who experience difficulty exhaling against the pressure, BiPAP is often the better choice. BiPAP can also be used for patients with central sleep apnea, where the issue is not the physical obstruction of the airway but the failure of the brain to send appropriate signals to the respiratory muscles.

BiPAP is also frequently used for individuals with chronic respiratory conditions, such as COPD or neuromuscular diseases, which may affect the lungs’ ability to properly exchange air. These patients may have difficulty exhaling against the continuous pressure of CPAP, and BiPAP’s ability to lower pressure during exhalation helps them breathe more comfortably and effectively. In these situations, the versatility of the BiPAP device, with its two distinct pressures for inhalation and exhalation, may make it a preferred option over CPAP, as it provides greater comfort and reduces the effort required to breathe for some people.

Comfort and Breathing Effort

Despite the advantages of BiPAP, there are some considerations related to the cost and accessibility of both devices. CPAP machines are generally less expensive than BiPAP machines because they are simpler in design and function. CPAP is often the first line of treatment for patients with obstructive sleep apnea, and many insurance plans cover the costs of CPAP therapy. BiPAP devices, on the other hand, are more specialized and are typically prescribed for patients with more complex needs. This can make BiPAP therapy more expensive, and insurance coverage may be more restrictive. Additionally, BiPAP devices tend to be more adjustable and may have additional features, such as a backup respiratory rate, which adds to their cost.

Ultimately, the choice between CPAP and BiPAP depends on the specific needs of the patient. CPAP remains the gold standard for treating obstructive sleep apnea, offering an effective, relatively simple, and affordable solution for those who can tolerate the continuous pressure. For patients with more severe or complex respiratory conditions, particularly those who experience difficulty exhaling against constant pressure, BiPAP provides a more customizable approach with two levels of pressure and greater comfort. The ability to adjust the pressures for inhalation and exhalation, as well as the potential for additional features such as backup respiratory rates, makes BiPAP an ideal choice for individuals with conditions such as central sleep apnea, COPD, or neuromuscular diseases.

Conclusion

In conclusion, while CPAP and BiPAP share the goal of improving airflow and preventing breathing interruptions during sleep, they differ significantly in their mechanisms of action, comfort, and indications for use. CPAP is effective for most cases of obstructive sleep apnea and offers a continuous flow of air at a single pressure, while BiPAP provides two distinct pressures—a higher one for inhalation and a lower one for exhalation—which is particularly beneficial for patients with more complex respiratory needs. Understanding the differences between these devices is essential for ensuring that the right treatment is chosen to support optimal respiratory health and improve the quality of life for patients with sleep apnea and other breathing disorders.

The Link Between Ehlers-Danlos Syndrome and Sleep Apnea

By Brandon Peters, M.D.

It may seem hard to believe, but could being double-jointed be an indication that you may be at risk for obstructive sleep apnea? Ehlers-Danlos syndrome (EDS) is a condition that affects cartilage throughout the body, including along the airway, and this may predispose afflicted individuals to sleep-disordered breathing, fragmented sleep, and daytime sleepiness. Learn about the symptoms, subtypes, prevalence, and link between Ehlers-Danlos and sleep apnea, and whether treatment may help.

What Is Ehlers-Danlos Syndrome (EDS)?

Ehlers-Danlos syndrome (EDS), or Ehlers-Danlos disorder, is a group of disorders that affect the connective tissues that support the skin, bones, blood vessels, and many other tissues and organs. EDS is a genetic condition that impacts the development of collagen and associated proteins that serve as the building blocks for tissues. Its symptoms have a range of potential severity, causing mildly loose joints to life-threatening complications.

Mutations in more than a dozen genes have been linked to the development of EDS. Genetic abnormalities affect the instructions for making pieces of several different types of collagen, a substance that gives structure and strength to connective tissues throughout the body. The collagen and associated proteins may not be assembled properly. These defects lead to weakness in tissues in the skin, bones, and other organs.

There are both autosomal dominant (AD) and autosomal recessive (AR) forms of inheritance, depending on the subtype of EDS. In AD inheritance, one copy of the altered gene is enough to cause the disorder. In AR inheritance, both copies of the gene must be altered for the condition to occur and parents may often carry the gene but be asymptomatic.

Combining the various forms, EDS is estimated to affect about 1 in 5,000 people.

The Symptoms of Ehlers-Danlos Syndrome

The symptoms associated with Ehlers-Danlos syndrome vary depending on the underlying cause and subtype. Some of the most common symptoms include:

Joint hypermobility

There may be an unusually large range of joint movement (sometimes referred to as being “double-jointed”).  These loose joints may be unstable and prone to dislocation (or subluxation) and cause chronic pain.

Skin changes

The skin may be soft and velvety. It is highly stretchy, elastic, and fragile. This may contribute to easy bruising and abnormal scarring.

Weak muscle tone

Infants may have weak muscles with delays in motor development (affecting sitting, standing, and walking).

Additional Symptoms

There are a number of additional symptoms associated with Ehlers-Danlos syndrome, including:

• Scoliosis at birth

• Chronic pain (often musculoskeletal and affecting joints)

• Early onset osteoarthritis

• Poor wound healing

• Mitral valve prolapse

• Gum disease

• Excessive daytime sleepiness

• Fatigue

• Impaired quality of life

It can be helpful to review the six subtypes of EDS in order to better understand the associated symptoms and potential risks.

Understanding the 6 Subtypes of Ehlers-Danlos Syndrome

In 1997, there was a revision in the classification the various subtypes of Ehlers-Danlos syndrome. As a result, six major types distinguished by signs, symptoms, underlying genetic causes, and patterns of inheritance were identified. These subtypes include:

Classical type: Characterized by wounds that split open with little bleeding, leaving scars that widen over time to create “cigarette paper” scars. This type carries a lesser risk of blood vessel tearing. It has an autosomal dominant inheritance, affecting 1 in 20,000 to 40,000 people.

Hypermobility type: The most common subtype of EDS, it manifests with predominately joint symptoms. It is autosomal dominant and may affect 1 in 10,000 to 15,000 people.

Vascular type: One of the most serious forms, it may cause life-threatening, unpredictable tearing (or rupture) of blood vessels. This may cause internal bleeding, stroke, and shock. There is also an increased risk of organ rupture (affecting the intestine and the uterus during pregnancy). It is autosomal dominant, but only affects 1 in 250,000 people.

Kyphoscoliosis type: Often characterized by severe, progressive curvature of the spine that can interfere with breathing. It carries a reduced risk of blood vessel tearing. It is autosomal recessive and rare, with only 60 cases reported worldwide.

Arthrochalasia type: This EDS subtype may be discovered at birth, with hypermobility of the hips causing dislocations of both sides with delivery. It is autosomal dominant with about 30 cases reported worldwide.

Dermatosparaxis type: An extremely rare form, it manifests with skin that sags and wrinkles, causing extra redundant folds that may become more prominent as children get older. It is autosomal recessive with only a dozen cases noted worldwide.

Sleep Complaints in EDS and the Link to OSA

What is the link between Ehlers-Danlos syndrome and obstructive sleep apnea? As noted, the abnormal development of cartilage affects tissues throughout the body, including those that line the airway. These problems may impact the growth and development of the nose and maxilla (upper jaw) as well as upper airway stability. With abnormal growth, the airway may be narrowed, weakened, and prone to collapse.

Recurrent partial or complete collapse of the upper airway during sleep causes sleep apnea. This may lead to drops in blood oxygen levels, fragmentation of sleep, frequent awakenings, and reduced sleep quality. As a result, excessive daytime sleepiness and fatigue may occur. There may be increased cognitive, mood, and pain complaints. The other symptoms of sleep apnea, such as snoring, gasping or choking, witnessed apnea, waking to urinate (nocturia), and teeth grinding (bruxism) may also be present.

A prior small survey of EDS patients from 2001 supports increased difficulties with sleep. It was estimated that of those with EDS, 56% had difficulty maintaining sleep. In addition, 67% complained of periodic limb movements of sleep. Pain, especially back pain, was increasingly reported by EDS patients.

How Common Is Sleep Apnea in Ehlers-Danlos Syndrome?

Research suggests that sleep apnea is relatively common among those with EDS. A recent study of 100 adults by Gaisl and colleagues, suggests that 32% of those with Ehlers-Danlos syndrome have obstructive sleep apnea (compared to just 6% of controls). These individuals were identified as having hypermobile (46%), classical (35%), or other (19%) subtypes. They were noted to have an increased level of daytime sleepiness as measured by the Epworth sleepiness score. The degree of sleep apnea correlated with the level of daytime sleepiness as well as a lower quality of life.

Treatment of Sleep Apnea and the Response to Therapy in EDS

When sleep apnea is identified, clinical experience supports a favorable response to treatment among patients with Ehlers-Danlos syndrome. As age increases, sleep-disordered breathing may evolve from limited airflow and nasal resistance to more apparent hypopnea and apnea events that characterize sleep apnea. This abnormal breathing may go unrecognized. Daytime sleepiness, fatigue, poor sleep, and other symptoms may be overlooked.

Fortunately, the use of continuous positive airway pressure (CPAP) therapy may provide immediate relief if sleep apnea is properly diagnosed. Further research is needed to assess the clinical benefit of sleep apnea treatment in this population.

If you feel you may have symptoms consistent with Ehlers-Danlos syndrome and obstructive sleep apnea, start by speaking with your doctor about evaluation, testing, and treatment.

Do You Need Distilled Water for the CPAP Humidifier?

Continuous positive airway ressure (CPAP) therapy is a commonly prescribed treatment for people with obstructive sleep apnea (OSA). CPAP machines help keep the airway open during sleep by delivering a continuous stream of air through a mask. To improve comfort during use, many CPAP machines are equipped with a humidifier, which adds moisture to the air to prevent dryness in the nose, throat, and airways. However, when using a CPAP humidifier, one key consideration is the type of water to use: Is distilled water necessary, or can you use tap water instead?

The Role of Humidification in CPAP Therapy

A humidifier is an optional but beneficial feature for many CPAP users. Without it, the air delivered by the machine may feel dry, leading to discomfort like a dry mouth, sore throat, nasal congestion, nosebleeds, or irritation in the respiratory system. The humidifier adds moisture to the air before it reaches the patient’s airway, which can reduce these symptoms and promote better sleep.

For optimal performance, many CPAP machines come with a water chamber designed to hold water that gets vaporized and introduced into the airflow. The type of water used in this chamber can impact the performance and longevity of the machine, as well as the user’s comfort.

The Importance of Using the Right Type of Water

When it comes to CPAP humidification, using the correct type of water is critical. The two main types of water you can use in the humidifier are distilled water and tap water. Each has its own characteristics, and choosing the right one for your CPAP machine is essential for maintaining both the machine and your health.

Distilled Water: The Preferred Choice

Distilled water is essentially water that has been purified by boiling it into steam and then condensing it back into water, leaving behind minerals, contaminants, and impurities. This process ensures that the water is free of particles that might otherwise be present in regular tap water.

Why distilled water is recommended:

1. Prevents Mineral Build-Up: One of the biggest reasons to use distilled water in your CPAP humidifier is to avoid mineral deposits (called scale). Tap water, depending on your location, often contains minerals like calcium and magnesium, which are left behind as the water evaporates in the humidifier. Over time, these minerals can accumulate and form hard water deposits in the water chamber, the hoses, and the CPAP mask. These deposits can lead to clogging and reduce the efficiency of the device. They may also potentially create a breeding ground for bacteria and mold, which could compromise your respiratory health.

2. Reduces Bacterial Growth: Distilled water is free from impurities and microorganisms that may be present in regular tap water. While the high humidity in the water chamber creates a conducive environment for microbial growth, using distilled water minimizes the chances of introducing harmful bacteria or mold into the machine. If regular tap water were to be used, the added minerals and contaminants could encourage bacterial growth, which can lead to respiratory infections or other health issues.

3. Improves Longevity of Your CPAP Machine: Using distilled water can help extend the lifespan of your CPAP humidifier. Hard water deposits from tap water can damage the water chamber, obstructing airflow or causing the humidifier to malfunction. By using distilled water, you help protect the components of your CPAP machine from unnecessary wear and tear, ensuring it works more efficiently and lasts longer.

4. Avoids Unpleasant Odors: Over time, tap water’s mineral content may interact with the humidifier and the air, leading to unpleasant odors or tastes when inhaling the humidified air. This is most evident if the water completely boils off in overnight use. Distilled water prevents this by ensuring that the water remains pure and free from any impurities that could alter its smell or taste.

Tap Water: The Risky Option

While it may seem more convenient and economical to use tap water, especially in areas with soft water, there are potential risks involved. In many cases, tap water can contain dissolved minerals, chlorine, fluoride, and even microorganisms like bacteria, fungi, or protozoa, which can pose risks to health and the functionality of the CPAP machine.

Why tap water should be avoided:

1. Mineral Deposits: As mentioned earlier, the minerals in tap water, especially in hard water areas, can accumulate in the water chamber, creating scale buildup and clogs. This not only makes cleaning more difficult but can also decrease the efficiency of the humidifier.

2. Bacterial and Mold Growth: Tap water can sometimes harbor bacteria or mold spores, particularly if the water has been sitting in the humidifier for an extended period of time. This can introduce harmful microbes into the air you are breathing, increasing the risk of respiratory infections or allergies.

3. Frequent Cleaning Required: If you use tap water, you will need to clean your CPAP machine and humidifier more frequently to prevent buildup and microbial growth. Distilled water, by contrast, can help reduce the frequency of deep cleaning sessions.

What About Filtered or Bottled Water?

In areas with particularly poor tap water quality, some users may wonder if filtered or bottled water is a suitable alternative. While filtering water can remove some of the contaminants, it may not eliminate all minerals or microorganisms. Bottled water is generally safe, but it still might contain trace amounts of minerals, depending on the brand and source. For these reasons, distilled water remains the safest and most effective choice for use in CPAP humidifiers.

Conclusion

While it is technically possible to use tap water in a CPAP humidifier, it is not advisable due to the risk of mineral buildup, bacterial growth, and potential damage to your CPAP machine. Distilled water, on the other hand, is specifically recommended for its purity and ability to prevent issues related to contamination and scale buildup.

Within the United States, distilled water may readily be available at most grocery stores. Distilled water may be hard to find on international trips, as it may only be for sale in pharmacies or hardware stores.

To ensure optimal performance of your CPAP therapy and avoid unnecessary cleaning, maintenance, or health risks, distilled water is the preferred choice. While it might cost a little more than tap water, the benefits far outweigh the potential issues caused by using untreated water. By taking this simple precaution, you can improve the comfort and longevity of your CPAP system, as well as protect your respiratory health.

Sleep Apnea Advice: Should I Use CPAP With a Cold?

Continuous positive airway pressure (CPAP) therapy is the most common and effective treatment for obstructive sleep apnea (OSA). It works by delivering a steady stream of air through a mask, helping to keep the airway open during sleep. However, if you have a cold, you may wonder whether you should continue using your CPAP machine. This article will explore the considerations, challenges, and best practices for using CPAP when you have a cold, as well as the importance of maintaining effective sleep apnea management.

Understanding CPAP Therapy

CPAP therapy involves using a machine that generates a constant flow of air to prevent airway obstruction during sleep. This air pressure keeps the throat open, reducing or eliminating apneas and hypopneas, which are the primary breathing events of OSA. For many individuals, adhering to CPAP therapy is essential for effective management of sleep apnea, as it can significantly reduce daytime sleepiness, improve overall health, and lower the risk of related complications.

The Impact of a Cold on CPAP Use

When you have a cold, you may experience nasal congestion, a runny nose, sneezing, coughing, and general discomfort. These symptoms can impact your CPAP therapy in several ways:

1. Nasal Congestion: Congestion can make it difficult to breathe through your nose, which may lead to discomfort or inability to tolerate the CPAP mask. Many CPAP users rely on nasal breathing; if the nasal passages are blocked, users might need to switch to mouth breathing, which can lead to air leaks, dry mouth, and decreased effectiveness of the therapy.

2. Increased Secretions: A cold can lead to increased mucus production, which may require frequent mask cleaning and more frequent adjustments during the night. If you use a nasal mask, the added moisture from nasal secretions may also cause discomfort or affect the fit.

3. Coughing: If you have a persistent cough, using CPAP can be challenging. Coughing while wearing the mask can lead to dislodgement or discomfort, making it difficult to maintain the therapy throughout the night.

4. Overall Discomfort: Colds often come with a sense of fatigue and malaise, which can affect your ability to tolerate CPAP therapy. The discomfort associated with a cold may lead some individuals to forego their CPAP therapy altogether, which can have adverse effects on sleep apnea management.

Should You Use CPAP During a Cold?

While using CPAP during a cold can be uncomfortable, it is generally advisable to continue your therapy, especially if you have been diagnosed with moderate to severe sleep apnea. Stopping CPAP therapy can lead to an increase in apneas, resulting in disrupted sleep and daytime fatigue. Here are several considerations to keep in mind when deciding whether to use CPAP while experiencing a cold:

• Consult Your Healthcare Provider: Before making any changes to your CPAP therapy, it’s crucial to consult your healthcare provider or sleep specialist. They can provide personalized advice based on your specific situation and medical history.

• Consider Your Symptoms: Assess the severity of your cold symptoms. If your congestion is mild and manageable, you may be able to use your CPAP without significant issues. The pressure may clear the mucus and congestion. However, if you are experiencing severe nasal congestion or other debilitating symptoms, your comfort and ability to use the CPAP may be compromised.

• Try a Heated Humidifier: Many CPAP machines come with a heated humidifier feature. Using a humidifier can help alleviate nasal congestion and dryness, making it easier to breathe through your nose while using the machine. This may improve your comfort and tolerance for CPAP therapy during a cold.

• Switch to a Full-Face Mask: If nasal congestion is severe, consider switching to a full-face mask that covers both the nose and mouth. This allows for mouth breathing if necessary and can help maintain effective therapy. However, ensure that the mask fits properly to prevent air leaks.

• Nasal Saline Rinse: Before using your CPAP machine, consider using a saline nasal rinse to help clear nasal passages. This can provide temporary relief from congestion and make it easier to breathe while using CPAP.

• Maintain CPAP Hygiene: When you have a cold, it’s essential to maintain proper hygiene with your CPAP equipment. Ensure that your mask, tubing, and humidifier are clean to minimize the risk of infection. Consider using disposable mask liners or changing your mask more frequently if you have increased nasal secretions.

• Monitor Your Symptoms: If you find that using CPAP while having a cold is causing discomfort or exacerbating your symptoms, monitor your overall health. If symptoms worsen, consider reaching out to your healthcare provider for further guidance.

Potential Consequences of Skipping CPAP

For individuals with moderate to severe sleep apnea, skipping CPAP therapy—even for a single night—can have significant consequences. These may include:

1. Increased Apneas: Without CPAP, your airway may become obstructed, leading to increased apneic events. This can cause fragmented sleep and a reduction in overall sleep quality.

2. Daytime Fatigue: Missing CPAP therapy can lead to excessive daytime sleepiness, impairing your ability to function effectively throughout the day. This can affect work, relationships, and overall quality of life. Be cautious with driving!

3. Health Complications: Long-term cessation of CPAP therapy can increase the risk of cardiovascular issues, hypertension, and metabolic disorders. Maintaining consistent use of CPAP is essential for mitigating these risks.

4. Cognitive Effects: Poor sleep quality can impair cognitive function, memory, and attention, making it challenging to concentrate or make decisions.

Additional Tips for Using CPAP with a Cold

1. Stay Hydrated: Drink plenty of fluids to help thin mucus secretions, making it easier to breathe and use your CPAP machine comfortably.

2. Elevate Your Head: Consider using an extra pillow to elevate your head while sleeping. This position can help alleviate nasal congestion and improve airflow.

3. Avoid Irritants: Stay away from irritants such as smoke, strong odors, or allergens that may exacerbate your cold symptoms and make CPAP use more difficult.

4. Rest and Recovery: Ensure you’re allowing yourself time to rest and recover from your cold. Prioritize sleep hygiene, and make your sleeping environment as comfortable as possible.

5. Use Over-the-Counter Medications: Over-the-counter decongestants or antihistamines can help relieve nasal congestion and make CPAP use more tolerable. However, consult with a healthcare provider before using these medications, especially if you have underlying health conditions or are taking other medications.

Conclusion

Using CPAP therapy while experiencing a cold can present challenges, but it is generally advisable to continue treatment to manage sleep apnea effectively. Maintaining CPAP usage helps prevent the complications associated with untreated sleep apnea, including increased apneas, daytime fatigue, and health risks. By implementing strategies to enhance comfort and address cold symptoms, individuals can navigate the difficulties of CPAP use during illness.
