I remember the sheer relief flooding over me the night my husband finally started using his CPAP machine. After years of interrupted sleep, listening to sounds ranging from a gentle purr to a full-blown freight train, the promise of silence was golden. The first few weeks were bliss! But recently, a familiar, unwelcome sound has crept back into the bedroom the snoring. It’s quieter, maybe, but it’s definitely there. It’s understandable to be frustrated and confused if your husband is still snoring with a CPAP machine. You’re not the only one experiencing this, and fortunately, there are often identifiable causes and effective solutions.
Understanding CPAP Therapy: How It Should Work
Before we dive into the “why,” let’s quickly recap what that CPAP machine is actually supposed to be doing. CPAP stands for Continuous Positive Airway Pressure. Think of it like a gentle, constant stream of air that acts like a splint to keep your husband’s airway open while he sleeps.
The Basic Science: Keeping Airways Open
Snoring, and more seriously, obstructive sleep apnea (OSA), happens when the muscles in the throat relax too much during sleep, causing the airway to narrow or completely collapse. This vibration of tissues as air struggles to get through creates the sound of snoring with CPAP. A collapse leads to an apnea event – a pause in breathing. The CPAP machine delivers pressurized air through a mask, creating enough internal pressure to prevent that airway collapse. It’s like inflating a floppy tube just enough to keep it round.
Why Your Husband Snoring Usually Stops with Effective CPAP Use
When the CPAP is working correctly right mask, right pressure, good seal – it physically prevents the airway narrowing and tissue vibration that causes snoring. The continuous pressure ensures the path for air stays clear all night long. So, if your husband snoring has returned or never fully stopped, it signals that something in this equation isn’t quite right. The therapy isn’t being delivered effectively.
Is the CPAP Mask the Culprit for Ongoing Snoring of Your Husband?
Often, the first place to look when CPAP therapy isn’t silencing the snores is the mask. It’s the crucial interface between the CPAP machine and your husband’s airway.
The Critical Issue of Mask Leaks
This is probably the most common reason for continued snoring. If the mask doesn’t seal properly against his face, pressurized air escapes out instead of going down his airway. This leak means the effective pressure holding the airway open is reduced, potentially allowing those tissues to vibrate again hence, snoring.
Identifying Tell-Tale Signs of a Leak (Air hissing, dry eyes/mouth)
How can you tell if there’s a leak? Listen for hissing sounds around the mask seal. Does he complain of dry eyes (from air blowing into them) or an unusually dry mouth/throat in the morning? Can you feel air escaping if you run your hand near the edges of the mask while it’s on? Many newer CPAP machines also track leak rates, which can be reviewed.
How Leaks Prevent Effective Pressure Delivery
Imagine trying to inflate a balloon with a hole in it. You have to blow much harder, and it might never fully inflate. Similarly, a mask leak means the prescribed pressure isn’t reaching the back of his throat where it’s needed. The machine might even try to compensate by working harder, but it often can’t overcome a significant leak.
The Wrong Mask Type or Size for His Face
Not all masks are created equal, and neither are faces! Using a mask that isn’t suited to his facial structure, beard, or sleeping style can lead to poor sealing and leaks.
Comparing Full Face, Nasal, and Nasal Pillow Masks
- Nasal Pillows: Seal directly at the nostrils. Great for minimal contact, but require breathing through the nose and can be dislodged easily.
- Nasal Masks: Cover the nose from the bridge to the upper lip. A popular choice, but problematic if he tends to breathe through his mouth.
- Full Face Masks: Cover both the nose and mouth. Ideal for mouth breathers or those with frequent nasal congestion, but have a larger surface area, increasing potential leak points.
Importance of Professional Mask Fitting
Getting the right size and best CPAP mask for snoring is crucial. A mask that’s too small can dig in and cause sores, while one that’s too large will likely leak. Ideally, he should have been fitted by a professional CPAP supplier or sleep technician who could assess his facial structure and recommend appropriate styles and sizes. If he picked one online without trying it, this could be the issue.
Wear and Tear: Is the Mask Cushion Old or Damaged?
Mask cushions (the soft part that touches the face) don’t last forever. Over time, facial oils, cleaning, and general use cause them to soften, stretch, or tear. A worn-out cushion won’t create an effective seal. Check the manufacturer’s recommendations, but cushions often need replacing every 1-3 months, and the entire mask frame/headgear annually or as needed. If his cushion is old, yellowed, or visibly damaged, it’s likely contributing to leaks and snoring.
CPAP Pressure Settings: Too High, Too Low, or Just Right?
The ‘P’ in CPAP is ‘Pressure,’ and getting this setting correct is vital. It’s a prescription tailored to counteract his specific level of airway collapse.
Insufficient Pressure: Still Allowing Airway Collapse
If the prescribed pressure setting is too low, it simply won’t be enough to consistently keep his airway open throughout the night, especially during deeper sleep stages (like REM) when muscles are most relaxed. This allows partial collapses and vibrations or snoring.
Why the Initial Setting Might Need Adjustment
The pressure determined during his initial sleep study (titration) might need tweaking over time. Factors like weight changes (up or down), changes in health, or even just the body adapting can mean the original setting is no longer optimal. Your husband continued snoring despite using CPAP may indicate that his current pressure settings need to be reviewed.
Excessive Pressure: Leading to Discomfort and Leaks?
Counterintuitively, pressure that’s too high can also sometimes contribute indirectly to snoring. While high pressure should keep the airway wide open, it can also cause discomfort, mask leaks (by literally pushing the mask away from the face), or a condition called aerophagia.
Potential for Aerophagia (Air Swallowing)
Aerophagia is where excessive air pressure forces air down the esophagus into the stomach, causing bloating, gas, and discomfort. This discomfort might lead him to unconsciously break the mask seal or adjust his position in ways that compromise therapy, potentially leading back to snoring.
Understanding Auto-CPAP (APAP) vs. Fixed Pressure
Some machines deliver a fixed pressure all night (CPAP). Others are auto-adjusting (APAP), meaning they have a pressure range and automatically increase or decrease the pressure based on detected breathing events like snoring or apneas. If he has an APAP, is the range set correctly? If he has a fixed CPAP, maybe an APAP would be more effective if his pressure needs vary throughout the night.
Warning: Never Adjust Pressure Without Doctor Consultation
This is critical: Do not try to change the CPAP pressure settings yourself based on guesswork. It’s a prescribed medical setting. Adjusting it incorrectly could make the therapy ineffective or even cause harm for your husband. Any concerns about pressure must be discussed with his sleep doctor or CPAP provider.
Why Is My ResMed CPAP Machine Not Turning On? Steps to Fix
The Mouth Breathing Problem with Nasal CPAP
If your husband uses a nasal CPAP mask or nasal pillows but naturally breathes through his mouth sometimes during sleep, you’ve found a likely culprit for the continued snoring.
Why Breathing Through the Mouth Defeats a Nasal Mask
A nasal CPAP delivers pressurized air into the nose, expecting it to flow down the back of the throat. If he opens his mouth, that pressurized air takes the path of least resistance and flows right out of his mouth. This massive “leak” dramatically reduces the pressure actually reaching his airway, making the therapy ineffective and allowing snoring to return. He might also wake up with an extremely dry mouth.
Solutions for Mouth Breathers Still Snoring with CPAP
If mouth breathing is the issue, there are two main solutions:
Trying a Chin Strap
A CPAP chin strap is a simple device worn under the chin and around the head to gently hold the mouth closed during sleep, encouraging nasal breathing. This can be very effective for some.
Switching to a Full-Face Mask
If a chin strap isn’t comfortable or effective, the next logical step is switching to a full-face mask that covers both the nose and mouth. This ensures that whether he breathes through his nose, mouth, or both, the therapeutic pressure is delivered.
Lifestyle Factors Affecting CPAP Effectiveness
Sometimes, the CPAP setup is technically fine, but external factors are undermining its success.
Has He Gained Weight Recently?
Even a modest weight gain (10% or more) can worsen sleep apnea and snoring by increasing fatty tissue around the neck and airway. The previously effective CPAP pressure might no longer be sufficient to counteract this increased resistance. Weight loss, conversely, can sometimes reduce the pressure needed.
Alcohol, Sedatives, or Muscle Relaxants Before Bed
Alcohol and certain medications (like sedatives, sleeping pills, or muscle relaxants) relax muscles throughout the body, including those in the throat. This makes the airway more prone to collapse, potentially requiring a higher CPAP pressure than usual to overcome. Avoiding these substances, especially close to bedtime, is crucial for effective CPAP therapy.
Sleeping Position: Is He Rolling onto His Back?
Sleeping flat on the back often worsens snoring and sleep apnea due to gravity pulling the tongue and soft tissues backward, further obstructing the airway. While CPAP is designed to work in any position, severe obstruction when supine might challenge the current pressure setting. Positional therapy (using pillows or devices to encourage side sleeping) might help in conjunction with CPAP.
Could Other Health Issues Be Contributing to His Snoring?
While OSA is the most common reason for CPAP use, other factors related to the nose and airway can interfere.
Nasal Congestion: Allergies, Colds, or Sinus Issues
If his nasal passages are blocked due to allergies, a cold, or chronic sinusitis, it’s difficult for the CPAP air to get through effectively, especially with a nasal mask. This can lead to mouth breathing (and associated leaks/snoring) or just general discomfort. Using a saline nasal spray, a humidifier on the CPAP, or treating underlying allergies (perhaps with guidance from an allergist or ENT) might be necessary. Find more information on managing allergies from the Asthma and Allergy Foundation of America.
Structural Problems: Deviated Septum or Nasal Polyps
Physical blockages in the nose, like a deviated septum (where the wall between nostrils is crooked) or nasal polyps (soft growths), can impede airflow and make CPAP less effective, potentially causing continued snoring sounds from the nasal area itself, even if the throat airway is open. An Ear, Nose, and Throat (ENT) specialist can diagnose and treat these issues.
Is it Obstructive Sleep Apnea (OSA) or Something Else?
While less common, it’s worth knowing that there are other forms of sleep apnea.
Brief Mention of Central or Complex Sleep Apnea
- Central Sleep Apnea (CSA) occurs when the brain doesn’t send the proper signals to the breathing muscles.
- Complex or Treatment-Emergent Sleep Apnea is when someone with OSA develops CSA after starting CPAP. Standard CPAP isn’t always the best treatment for these conditions; more advanced machines (like BiPAP or ASV) might be needed. Persistent issues despite optimized CPAP could warrant investigation into these possibilities by a sleep specialist.
CPAP Machine Maintenance and Usage Habits
The machine itself and how it’s used are fundamental.
Compliance Check: Is He Using CPAP All Night, Every Night?
“Compliance” means using the CPAP consistently. For best results, it should be worn for all sleep periods, including naps. If your husband takes it off halfway through the night because it’s uncomfortable, snoring can obviously return during the non-CPAP hours. Most machines track usage hours, which can provide valuable data. Aim for at least 4-6 hours per night, ideally the entire duration of sleep.
Dirty Filters: Restricting Airflow?
CPAP machines have filters (usually disposable and sometimes a reusable one) to clean the air drawn into the machine. If these filters are clogged with dust and debris, it restricts airflow, potentially reducing the pressure delivered to the mask. Check and replace/clean filters according to the manufacturer’s schedule (often monthly for disposable, washable as needed for reusable).
Humidifier Issues: Dryness Leading to Discomfort or Congestion
Most CPAPs have heated humidifiers to add moisture to the pressurized air, preventing dryness and irritation in the nose and throat. If the humidifier isn’t filled with distilled water, isn’t working correctly, or the setting is too low, the resulting dryness can cause nasal congestion or discomfort. Leading to mask removal or mouth breathing and yes, potentially snoring. Ensure it’s used correctly and the water chamber is clean.
Taking Action: Troubleshooting Steps and Seeking Help
Okay, that’s a lot of possibilities if your husband snoring with CPAP! So, what do you do now?
Initial Checks: Mask Fit, Straps, Leaks
Start with the basics tonight. When he puts the mask on, help him check the seal. Are the straps too tight or too loose? (Overtightening can actually cause leaks). Lie down in his usual sleeping position and listen/feel for escaping air. Adjust the mask and headgear gently for the best seal without discomfort. Check the cushion for wear.
Reviewing CPAP Machine Data (If Available)
Many modern CPAPs record data like usage hours, leak rate, and AHI (Apnea-Hypopnea Index – the number of breathing events per hour). This data can often be accessed via an app or SD card. High leak rates are a red flag. An elevated AHI despite good usage suggests the pressure might be inadequate or another issue is present.
When to Schedule a Follow-Up with the Sleep Specialist or CPAP Provider
If simple adjustments don’t resolve the snoring, or if you suspect issues with pressure, compliance, or underlying health conditions, it’s time to call the professionals. Contact his sleep doctor or the durable medical equipment (DME) provider who supplied the CPAP.
Discussing Symptoms and Potential Need for Titration Study
Be specific about the continued snoring, any discomfort he’s experiencing, and observations about leaks or mouth breathing. They may be able to make adjustments remotely, suggest different mask options, or schedule an appointment. In some cases, especially if weight or health has changed significantly, they might recommend a repeat titration study to determine the optimal pressure settings now.
Conclusion: Finding the Quiet Again When Your Husband is Still Snoring with CPAP
It can be frustrating and make you doubt the effectiveness of CPAP therapy when your husband continues to snore despite using it. But as we’ve explored, there are numerous potential reasons, ranging from simple mask adjustments to more complex pressure or health issues.
The key is not to ignore it. Work together as a team check the mask, review habits, and don’t hesitate to reach out to his sleep specialist or CPAP supplier. Effective CPAP therapy can eliminate your husband snoring and significantly improve sleep quality and health for both of you. Persistence and professional guidance are your best allies in getting back to those peaceful, quiet nights you both deserve.

Frequently Asked Questions (FAQs)
While uncommon, if the pressure is too low, it might not stop snoring effectively. If it’s causing significant leaks or discomfort leading to poor usage, snoring might seem worse during the off-periods or due to leak noise. It doesn’t inherently worsen the underlying condition, though.
Signs include continued snoring, high AHI on machine data despite good usage, excessive mask leaks (sometimes from high pressure), feeling tired despite using CPAP, or discomfort like air swallowing (aerophagia). Only a doctor can definitively say and adjust the prescription.
Absolutely. An ill-fitting mask or the wrong style (e.g., a nasal mask for a mouth breather) is a primary cause of leaks. Leaks reduce effective pressure, allowing snoring. Finding the right mask type and size for his face and breathing habits is crucial.
Yes, nasal congestion from allergies can make it hard for air to pass through the nose, potentially causing nasal vibration sounds (snoring) or forcing mouth breathing, which compromises nasal CPAP effectiveness. Managing allergies is important for successful CPAP use.
If you’ve addressed mask fit, leaks, pressure (with professional help), compliance, and lifestyle factors, consult the sleep specialist again. They may consider a repeat sleep study, investigate underlying nasal issues, or explore possibilities like complex sleep apnea requiring different therapies.
