What This Tool Does

The CPAP Troubleshooter is a fixed set of hand-written rules, not an AI chatbot. You pick up to 3 of the 22 problems below, and it returns the fixes most likely to help, in order, with a link to the guide behind each one. Fixes that help with more than one of your picks come first.

Some problems are not yours to fix alone. Morning headaches, nosebleeds, ear pressure, skin that breaks down, feeling tired despite using CPAP, and a high AHI or central apneas all send you to your provider first, above any other suggestion.

Where your own data can show whether a fix is working, such as your leak trend for mouth breathing or the nights your mask came off, the results point you to it. Your files are read in your browser and never uploaded. The tool does not replace medical advice; it gives you a starting point and a checklist for the conversation with your provider.

The 22 Problems It Covers

Mask and seal

  • Leak at top of mask. Air blows into your eyes or over the top of the mask.
  • Leak at side of mask. Whistling or air escape at the cheek or jaw seal.
  • Mouth breathing. Mouth falls open and air escapes overnight.
  • Waking with the mask off. You find the mask off in the morning or in the night.
  • Sore spot on nose. Pressure mark or soreness on the bridge of the nose.
  • Red marks, rash or skin sores. Marks that last for hours, a rash, or broken skin where the mask sits. Goes to your provider first.
  • Machine or mask noise. Loud enough to disturb you or a partner.

Air, water and dryness

  • Dry mouth. Wake up with a dry mouth.
  • Sore or dry throat. A scratchy or sore throat in the morning.
  • Nose stuffiness. Congestion or runny nose after starting CPAP.
  • Nosebleeds. Bleeding or a raw, crusty nose. Goes to your provider first.
  • Dry or irritated eyes. Eyes feel dry, red or gritty when you wake.
  • Water in tube or mask. Gurgling, drips or water on your face (rainout).
  • Bloated stomach. Bloating, burping, or gas from swallowing air during therapy.

Falling and staying asleep

  • Claustrophobic feeling. The mask feels suffocating or triggers anxiety.
  • Can't fall asleep. Lying awake with the mask on for more than about 30 minutes.
  • Pressure too strong. Air delivery feels overwhelming or uncomfortable.
  • Hard to exhale. Breathing out feels like pushing against a wall.

How you feel and what your data shows

  • Still tired on CPAP. Tired during the day even though you use it. Goes to your provider first.
  • Morning headaches. Waking with a headache on CPAP. Goes to your provider first.
  • Ear pressure or popping. Fullness, popping or pain in your ears. Goes to your provider first.
  • AHI high or central apneas showing. Your machine or app shows a high AHI or central events. Goes to your provider first.

You can pick up to 3. Once you have 3, the others wait until you remove one, so a pick is never dropped without you seeing it.

How the Ranking Works

Each fix is tagged with the problems it addresses. The tool counts how many of your picks each fix covers, and fixes that cover more of them rank higher. Ties keep a fixed editorial order. Each fix carries one of three labels, Most likely to help, Worth trying or If others fail. The labels reflect how well a fix matches your picks, not a measured success rate.

The same picks always give the same results. There is no machine learning and no personalization. We count anonymous tool use (for example, which problems were picked and which fix came out on top) and nothing that identifies you. Comfort settings such as exhale relief, ramp and humidity are named so you can ask about them, never adjusted for you here.

When to Contact Your Provider

Many CPAP problems ease with a better fit, fresh supplies, or time. Some need professional attention.

  • Morning headaches while using CPAP
  • Feeling tired during the day even though you use CPAP every night
  • A residual AHI that stays high, or central apneas that keep showing up
  • Nosebleeds that keep happening or do not ease with humidification and saline spray
  • Ear pain, ear pressure that keeps coming back, or changes in your hearing
  • Broken skin that is not healing, open sores, or a rash where the mask sits
  • Bloating that is severe or keeps you from using CPAP
  • Any problem that is still there after two or more weeks of trying the fixes
  • Error codes, or grinding, clicking, or rattling noises from the machine

If you have chest pain or trouble breathing, call 911 or get emergency care.

Your sleep physician decides your therapeutic pressure settings, can order a different device type, and can look at whether your symptoms point to a shift in your underlying condition. Your equipment supplier can help with mask fitting, replacements, and showing you your machine's comfort settings.

Frequently Asked Questions

When should I call my provider instead of self-troubleshooting?

Self-troubleshooting suits comfort problems like dry mouth, minor mask leaks, and rainout. Contact your sleep physician or equipment supplier if a problem is still there after two weeks of trying fixes, if new symptoms appear, if your machine shows error codes or makes unusual noises, or if your AHI stays high or central apneas keep showing up. Morning headaches, nosebleeds that keep happening, ear pain or hearing changes, and broken skin that is not healing are also for your provider. If you have chest pain or trouble breathing, call 911 or get emergency care.

How often should I replace my CPAP supplies?

There are two schedules, and they answer different questions. Medicare's is a coverage limit, not a rule you have to follow, and comes from the CMS Local Coverage Determination L33718 (PAP devices). It allows nasal pillows up to 2 a month, nasal mask cushions up to 2 a month, full-face cushions up to 1 a month, tubing up to 1 every 3 months, disposable filters up to 2 a month, headgear and chin straps up to 1 every 6 months, and the water chamber up to 1 every 6 months. The makers' own guidance differs by part. ResMed suggests a silicone cushion every 6 months and a memory-foam one every 1 month (ResMed Australia patient guidance, 2021), and its machine guides list tubing and the air filter every 6 months (ResMed AirSense 10 and 11 user guides). Private plans set their own limits. Replace any part sooner once it is worn; worn supplies are a common cause of leaks and skin irritation.

Can adjusting machine settings fix my side effects?

Some side effects respond to comfort settings. The exhale-relief setting (EPR on ResMed, Flex on Philips) lowers the pressure as you breathe out, which many people find makes exhaling easier. Ramp starts therapy at a gentle starting pressure and builds up to your prescribed level, which can make it easier to fall asleep. Heated humidification and heated tubing can help with dry mouth, nasal congestion, and rainout. Some comfort settings can be changed on the machine itself, but if your provider set it, change it only with them. Your prescribed pressure is always your provider's decision.

Is aerophagia dangerous?

Aerophagia (swallowing air during CPAP use) is uncomfortable rather than dangerous. Symptoms include bloating, gas, and belching. For some people it eases over the first weeks of therapy. Sleeping on your left side, raising the head of the bed slightly, and avoiding large meals and fizzy drinks close to bedtime help some people. Your pressure and comfort settings may also play a part, and those are your provider's call. If it is severe or keeps you from using CPAP, contact your provider rather than stopping therapy. They may review your settings or consider a bilevel (BiPAP) machine.

Why does my mask leak only on some nights?

Intermittent mask leaks usually have a positional cause. Sleeping on your side can shift the mask, especially full-face masks. Mouth opening during sleep causes large leaks on nasal masks and nasal pillows. Other variables include pillow type (soft pillows can push the mask frame), facial hair growth, skin oiliness, and whether you adjusted the headgear differently that night. If leaks correlate with sleeping position, consider a mask designed for side sleepers or a CPAP-specific pillow with cutouts. If mouth opening is the cause, a chin strap or switching to a full-face mask may resolve it.
