How to Document CPAP Intolerance So Your Sleep Service Will Consider an Alternative

What documenting CPAP intolerance really takes

The short answer is that a sleep service acts on a dated, specific record rather than a general complaint, so a four-week usage curve, a dated side-effect log and your original sleep study carry more weight than how you describe the problem. A switch is usually decided at a review point, which means the file you bring is what moves it.

It helps to separate two things that sound alike. Intolerance means the therapy was used, or genuinely attempted, and could not be sustained because of real side effects. That is different from the therapy simply not lowering your breathing events, and a service reads the two very differently.

The aim behind all of it is a treated, open airway. Sleep apnoea comes from the upper airway collapsing during sleep, so the question a clinician is really asking is whether any option you move to will keep that airway open and maintain enough airflow through the night.

Build the four-week record

The first four weeks decide the case, because early use predicts what follows. In a 2025 cohort published in Thorax, 98% of patients who were not adherent by month three had already fallen short in the first month, so a clear early record is persuasive (Thorax, BMJ, 2025).

Gather the evidence a service can read at a glance:

• a printed 28-day usage curve with nightly hours, residual events, leak and pressures
• a dated side-effect log with a simple severity score each night
• a record of every mask and setting you have tried
• your Epworth sleepiness score at diagnosis and today
• your original sleep study report, which fixes your AHI band

If the machine belongs to a homecare provider, ask for the data in writing and cite GDPR Article 15. As the data controller for your telemonitoring stream, the provider has to give you a copy of what it processes. It also helps to read up on common CPAP side effects and fixes and on ways to stick with therapy before the review.

Where Back2Sleep fits in the conversation

While you build that file, it is worth knowing one of the options you might raise with your clinician. Back2Sleep is a soft medical-grade silicone intranasal stent that sits inside the nasal passage and helps hold the upper airway open during sleep, so enough airflow is maintained without a machine.

It is intended for snoring and sleep apnea and needs no prescription, no electricity, no noise and no tubing. The starter kit, the SnoreKit, includes the four sizes S, M, L and XL so you can find your fit. It is a CE-marked Class I medical device, designed in France and made in Germany, and the site reports results in mild to moderate apnea.

It may suit someone with mild to moderate apnoea who has struggled with positive airway pressure, discussed with a doctor first. It is not a replacement for that therapy, and severe apnea is a medical decision that belongs with your clinician.

What your service can switch you to

Services do switch people, and the evidence supports it. In the multicentre CHOICE trial, 55% of participants chose to alternate between a mandibular advancement splint and positive airway pressure, and the splint matched the machine on nightly use (European Respiratory Journal, 2025). The usual destinations are an oral appliance, positional therapy, a nasal approach, or surgery in selected cases.

The rules depend on where you live. In France, failure or intolerance of positive airway pressure is listed as an indication for a mandibular advancement device aimed at an AHI between 15 and 30, through the prior-agreement process, and cover for the device replaces cover for the machine. In the UK, NICE guidance says a splint can be considered when the machine is not tolerated, for adults with healthy teeth and gums, though access is uneven.

Document a supervised switch rather than a quiet stop. A file that records an interim plan and a review date reads very differently from one that records abandonment, and it protects your driving position under EU Directive 2014/85/EU.
