CPAP Therapy: Adjusting and Tracking
Last updated: August 2026
CPAP — continuous positive airway pressure — is the standard treatment for obstructive sleep apnea: a quiet blower sends pressurized air through a hose and mask, splinting your airway open so it can't collapse. No medication, no surgery, and the effect is immediate on the nights you use it.
The catch is human: highly effective therapy, easy-to-abandon equipment. Most quitters stop in the first few weeks, over problems with straightforward fixes — here they are, plus why your clinic and insurer watch your nightly hours.
What the first weeks are actually like
A minority sleep well the first night; most take two to six weeks before the mask stops feeling foreign. Three things shorten it:
- Wear it while awake. An hour on the sofa with the machine running breaks the mask-anxiety link faster than anything.
- Use it every night, all night. Half-nights leave you tired, the machine feels pointless — the road to giving up.
- Call your provider early. Fit, ramp, and humidification are all adjustable; suppliers expect to swap masks in the first month. Struggling quietly is the commonest mistake.
The payoff is often quick — sharper mornings within days. If not, tell your clinician: information, not a reason to stop.
Common problems and what fixes them
Nearly every early problem is in this table, and nearly all are fixable. Anything involving pressure settings belongs to your clinician.
| Problem | Why it happens | What usually fixes it |
|---|---|---|
| Mask leak — air hissing, blowing into your eyes, waking to a loose mask | Wrong size or style, over-tightened straps, a worn cushion, turning over | Get re-fitted — size varies across styles; fit it lying down. Tighten less: overtightening deforms the cushion. Replace cushions on schedule; a liner or a different style (nasal pillows vs nasal vs full-face) often solves it. |
| Dry mouth and dry throat | Usually mouth-breathing overnight | Turn up the heated humidifier; a heated hose stops condensation. Ask about a chin strap or full-face mask, and treat the congestion that forces mouth-breathing. |
| Aerophagia — swallowed air, bloating, belching | Air down the esophagus, often from pressure higher than you currently need | Ask about a pressure review, exhale-relief (EPR/flex) settings, or auto-adjusting mode; side-sleeping helps. Report it, don't tolerate it. |
| Claustrophobia and mask anxiety | A natural response to something strapped to your face | Daytime desensitization: straps off, straps on, machine running, worn awake. Try minimal-contact nasal pillows; use the ramp. Persistent anxiety responds to a few behavioral-therapy sessions — ask. |
| Nasal congestion, sneezing, runny nose | Airflow drying and irritating the nasal lining | Humidification, a saline rinse before bed, and a word with your doctor about allergies or a deviated septum. |
| Skin marks, sores, a red nose bridge | Straps too tight, or the mask in the same spot nightly | Loosen until the seal just holds; clean the cushion daily (facial oils break the seal). Liners or a different style redistribute pressure. |
| Noise, hose drag, a disturbed partner | Hose drag pulling the mask off-seal; vent air at a partner | A hose lift or headboard routing stops turn-over leaks; a newly noisy machine needs a filter change or has a leak. |
Two things you should not do on your own: change your prescribed pressure settings, and stop therapy because you feel better. Sleep apnea returns the night you stop.
Cleaning and replacement, briefly
Two minutes a day: wipe the mask cushion with mild soap and water — facial oils cause the classic slow leak — wash cushion, headgear and hose weekly, refill the humidifier with distilled water, check the filter monthly, replace parts on your supplier's schedule. Skip ozone and UV "cleaner" gadgets unless your provider endorses one — manufacturers recommend soap and water.
Why nightly usage gets tracked
Every modern machine records how long it ran, and the number matters three ways.
Your clinic checks usage first when therapy isn't working — are the hours there, and do skipped nights line up with a cold, travel, a bad fit? Usage plus your notes turns "it's not helping" into something fixable.
Insurers and health systems commonly tie continued coverage to documented adherence during an initial trial — often four or more hours on most nights. Rules vary; the pattern is near-universal.
For you, the value is the pairing: machine hours plus a sleep diary of how you slept and felt answer the question that matters — is it working? And CPAP treats the airway, not a 2 a.m. bedtime; the habits in our sleep hygiene guide still do their share.
Logging it: machine data, paper, or app
Your machine's app stores hours, but not the human half — how rested you felt, the night you gave up at 3 a.m. and why — and it locks the record in one vendor's ecosystem. A notebook works; consistency beats sophistication. Sleep & CPAP Feeltracker keeps both halves in one place: a manual diary — no machine connection, no breathing measurement — with CPAP usage alongside sleep and wake times, quality and notes, charts and trends, export to PDF, XLSX, CSV or JSON for clinic reviews, reminders, widgets, Apple Health sync, iCloud sync with no account, and AI insights (free, with optional premium).
Log nightly for the first month — the stretch where a fixable problem is easiest to spot, and where most people quietly stop.
Frequently asked questions
How long does it take to get used to CPAP?
Most people need two to six weeks. Wearing the mask for an hour while awake, using it every night rather than half-nights, and asking for a re-fit early all shorten that considerably. Still fighting it after a month? That's a call to your provider, not a reason to stop.
How many hours a night do I need to use it?
All night, every night, is the goal — the apnea comes back the moment the pressure stops. Insurers commonly set a documented minimum during an initial trial (often around four hours on most nights), but that's a coverage floor, not a health target. The exact rule depends on your country, insurer and provider.
Why does CPAP make me bloated and burp?
That's aerophagia — air going down the esophagus instead of the airway. It often means the pressure is higher than you currently need. Ask your clinician about a pressure review or exhale-relief settings; sleeping on your side or slightly propped up helps too. Don't adjust prescribed settings yourself.
Can I stop CPAP once I feel better?
No — feeling better is the therapy working, not the apnea resolving. Stopping brings the breathing pauses back the same night. If weight loss, surgery, or a change in circumstances has you wondering whether you still need it, that's a re-test question for your doctor, not a decision to make at home.
Is there an alternative to CPAP?
Sometimes. Custom dental (mandibular advancement) appliances work for many people with mild to moderate apnea, positional therapy helps when apnea is mostly back-sleeping, weight loss can substantially reduce severity, and surgery addresses specific anatomy. Which applies depends on your sleep study results and your clinician's assessment.
