What Happens If You Stop Using CPAP? Why Consistency Matters

Starting CPAP therapy is an important step towards managing obstructive sleep apnoea (OSA), improving sleep quality and protecting your long term health. But adjusting to CPAP isn’t always easy.

An uncomfortable mask, air leaks, dryness, pressure discomfort or simply struggling to get used to sleeping with a device can leave some people wondering: What happens if I just stop using CPAP?

The important thing to understand is that CPAP manages obstructive sleep apnoea while you are using it , it does not usually cure the underlying condition. If you stop using your CPAP, your sleep apnoea may return, sometimes surprisingly quickly.

If you’re finding CPAP difficult, the answer isn’t necessarily to give up. Often, a relatively simple change to your mask, settings, humidification or routine can make therapy much more comfortable.

What Does CPAP Actually Do?

Obstructive sleep apnoea occurs when the upper airway repeatedly narrows or closes during sleep. These interruptions can reduce airflow, disturb sleep and cause drops in blood oxygen levels.

CPAP, or Continuous Positive Airway Pressure, provides a gentle flow of pressurised air through a mask while you sleep. This pressure acts like an air splint, helping to keep your airway open and allowing you to breathe more consistently throughout the night.

When your CPAP is correctly set up and working effectively, it can significantly reduce the breathing events associated with obstructive sleep apnoea.

However, that protection generally only occurs while you are actually using your therapy.

What Happens If You Stop Using CPAP?

For many people, stopping CPAP allows their obstructive sleep apnoea to return.

Research into CPAP withdrawal has shown that sleep apnoea can recur within just a few days of stopping treatment. Depending on the individual and the severity of their OSA, symptoms may also begin returning quickly.

You may notice:

  • Increased snoring
  • Waking frequently throughout the night
  • Gasping, choking or pauses in breathing during sleep
  • Morning headaches
  • Dry mouth on waking
  • Increased daytime tiredness or sleepiness
  • Poor concentration or “brain fog”
  • Irritability or changes in mood
  • Feeling unrefreshed despite spending enough time in bed

Some people notice these changes immediately. Others may not feel dramatically different at first.

That doesn’t necessarily mean their sleep apnoea has disappeared.

“But I Feel Fine Without My CPAP”

This is something we hear from time to time.

One of the tricky things about obstructive sleep apnoea is that you cannot always tell how well you are breathing while you’re asleep.

You may not remember waking when your airway becomes obstructed, and you cannot necessarily feel every drop in oxygen or disruption to your sleep.

This is why how you feel in the morning isn’t always a reliable way of determining whether your sleep apnoea is still present.

Studies examining CPAP withdrawal have found that OSA can return rapidly after treatment is stopped, including increases in apnoea hypopnoea events and oxygen desaturation.

If you believe your sleep apnoea may have improved  for example, following significant weight loss, surgery or another major health change  speak with your doctor or sleep specialist. They may recommend reassessing your sleep apnoea rather than stopping CPAP on your own.

Why Does Consistent CPAP Use Matter?

Think of CPAP a little like wearing prescription glasses.

Glasses help correct your vision while you’re wearing them, but taking them off doesn’t mean the underlying eyesight problem has been cured.

CPAP works in a similar way. While you are asleep with your CPAP running at an appropriate therapeutic pressure, it helps keep your airway open. When you stop using it, that support disappears.

Research has demonstrated that withdrawing CPAP can result in the rapid recurrence of obstructive sleep apnoea and daytime sleepiness. Studies have also observed increases in blood pressure and heart rate following short-term CPAP withdrawal.

Over the longer term, untreated obstructive sleep apnoea is associated with a range of health concerns, particularly when OSA is moderate or severe.

Consistency therefore matters. Ideally, CPAP should be used every time you sleep, including during naps and while travelling, unless your treating medical professional has advised otherwise.

What About Skipping CPAP for Just One Night?

Missing a single night doesn’t mean all of your progress has suddenly disappeared. However, your CPAP doesn’t provide ongoing airway support after you remove the mask.

Your sleep apnoea may therefore be present on nights when you don’t use your device.

This is why getting into the habit of using CPAP every night is so valuable. Rather than thinking of CPAP as something you use only when you’re particularly tired or when symptoms feel worse, try to make it part of your normal bedtime routine.

Going away for the weekend? Take your CPAP.

Sleeping somewhere other than home? Take your CPAP.

Having an afternoon nap? Use your CPAP if you’ve been advised to use therapy whenever you sleep.

Consistency is what allows CPAP to consistently do its job.

Why Do People Stop Using CPAP?

Most people don’t stop CPAP because they don’t care about their health.

They stop because something about their therapy isn’t working for them.

And that’s an important distinction.

Some of the most common CPAP difficulties include:

Mask leaks: Air escaping around the mask can be noisy, uncomfortable and reduce the effectiveness of therapy.

An uncomfortable mask: A mask may feel too tight, bulky or irritating, particularly if it isn’t the right size or style for your face.

Dry mouth or throat: Mouth breathing, mask leak or inadequate humidification may contribute to dryness.

A blocked or dry nose: Nasal congestion can make CPAP uncomfortable, particularly when using a nasal or nasal-pillow mask.

Pressure feels too high: Some people find it difficult to breathe against their prescribed pressure or experience discomfort as pressure increases during the night.

Pressure feels too low: Feeling like you’re not receiving enough air can also make falling asleep with CPAP difficult.

Removing the mask while asleep: This is particularly common when someone is still adapting to therapy.

Aerophagia or bloating: Swallowing air can result in bloating, burping or abdominal discomfort.

Claustrophobia: Some people initially find having a mask on their face overwhelming.

Skin irritation or pressure marks: These may be related to mask fit, overtightening, mask style or worn components.

The good news is that many of these problems can be addressed.

Before You Give Up on CPAP, Ask for Help

If you’re struggling with CPAP, you don’t have to simply tolerate it  and you don’t have to abandon your therapy either.

CPAP is not necessarily a one size fits all treatment.

Different people require different masks, pressures, comfort settings and humidification levels. Even small adjustments can make a significant difference.

Depending on the problem you’re experiencing, a CPAP review may involve:

  • Checking your mask fit and sizing
  • Trialling a different style of mask
  • Reviewing mask leak
  • Checking your therapy data
  • Reviewing your AHI and treatment effectiveness
  • Adjusting comfort features where appropriate
  • Reviewing humidification
  • Discussing dryness or nasal congestion
  • Checking whether your mask or equipment needs replacing
  • Helping you develop strategies to become more comfortable with therapy

Sometimes the solution is as simple as changing a cushion size. Other times, your therapy data may show that something more needs to be investigated.

Either way, asking for help is far better than quietly putting your CPAP machine in the cupboard.

“I Tried CPAP and Couldn’t Do It”

If you’ve previously stopped CPAP because you couldn’t tolerate it, it may still be worth trying again.

Your first experience doesn’t have to be your final experience.

Mask technology has continued to evolve, and there are now many different styles available, including nasal pillows, nasal masks, full face masks and minimal-contact options.

More importantly, proper support can make a huge difference.

Someone who struggled because their mask leaked all night may simply need a better fitting mask. Someone waking with an extremely dry mouth may need their humidification or mask choice reviewed. Someone who feels overwhelmed by pressure may benefit from having their therapy data and comfort settings assessed.

Instead of thinking, â€śCPAP doesn’t work for me,” it may be more useful to ask:

“What specifically isn’t working with my CPAP?”

Once the problem is identified, there may be a solution.

Don’t Wait Until You’ve Completely Given Up

If you’re starting to dread putting your mask on each night, regularly taking it off during your sleep or skipping CPAP more and more often, that’s a good time to seek support.

You don’t need to wait until your machine has been sitting unused for six months.

Early troubleshooting can help prevent a small annoyance from becoming the reason you stop therapy altogether.

CPAP therapy often involves some trial and error, particularly in the beginning. Finding the right combination of mask, fit, pressure, humidification and routine can take time.

The goal isn’t simply to own a CPAP machine.

The goal is to have therapy that is effective enough and comfortable enough that you can actually use it consistently.

Can You Ever Stop Using CPAP Permanently?

In some circumstances, a person’s treatment requirements can change.

Significant weight loss, surgery, dental treatment or other changes may affect the severity of obstructive sleep apnoea. Alternative treatments may also be appropriate for certain patients.

However, you shouldn’t assume your OSA has resolved simply because you feel better or because you’ve been using CPAP successfully for several years.

If you’re considering stopping CPAP permanently, speak with your GP, sleep physician or treating healthcare professional. A repeat sleep study or clinical reassessment may be recommended to determine whether you still require treatment.

The Bottom Line: Don’t Abandon CPAP Because You’re Struggling

If there’s one thing to take away from this article, it’s this:

Having difficulty with CPAP does not automatically mean CPAP isn’t suitable for you.

It may mean your current setup isn’t suitable for you.

Stopping CPAP can allow obstructive sleep apnoea and its associated symptoms to return, sometimes within only a few days. Consistent therapy helps maintain the airway support CPAP is designed to provide throughout your sleep.

So if your mask leaks, your mouth is dry, the pressure feels uncomfortable, you’re constantly pulling the mask off or you’re simply fed up with your machine  talk to someone before you give up.

A CPAP review can help identify what’s going wrong and what can be changed.

Sometimes a small adjustment is all it takes to turn frustrating therapy into comfortable, effective treatment.
