Fixed CPAP
A fixed CPAP (or constant pressure CPAP) is a machine that delivers the same air pressure all night, set by your doctor after a sleep study or titration. It is the ideal solution when your pressure needs are stable. Simpler, more affordable and just as effective as an auto CPAP for the right profile.
At VivaRespire, you'll find the three most popular fixed-pressure references: ResMed AirSense 11 Elite, Löwenstein prisma SOFT and Sefam EcoStar. Three reliable machines, direct purchase, EU delivery.

Fixed CPAP machines are devices used to treat obstructive sleep apnea that deliver a constant air pressure all night long. This pressure is determined during a sleep study or titration and remains stable throughout therapy.
Fixed CPAPs are a reliable, proven solution when pressure needs are constant, effectively keeping airways open during sleep.
What is a fixed CPAP used for?
A fixed CPAP prevents the obstruction of upper airways in people with sleep apnea. By delivering continuous, stable pressure, it prevents apneas, hypopneas and nocturnal micro-arousals.
This therapy improves sleep quality, reduces daytime drowsiness and limits cardiovascular risks linked to untreated sleep apnea.
How does a fixed CPAP work?
A fixed CPAP draws ambient air, filters it and sends it under pressure through a tube connected to a mask worn during sleep. Unlike auto CPAPs, the delivered pressure stays the same from the start to the end of the night.
The pressure is set to a precise value (in cmH₂O), defined by a healthcare professional based on the patient's respiratory needs.
The benefits of a fixed CPAP
- Stable, constant pressure, ideal when needs do not vary.
- Proven reliability for treating obstructive sleep apnea.
- Ease of use with fewer complex settings.
- Often more affordable than auto-adjusting models.
Models available at VivaRespire
- ResMed AirSense 11 Elite: fixed pressure, touchscreen, myAir app, the most used worldwide.
- Löwenstein prisma SOFT: made in Germany, among the quietest on the market (~26 dBA).
- Sefam EcoStar: made in France, robust, simple, reliable.
How to choose a fixed CPAP?
Choosing a fixed CPAP relies on several key criteria:
- the prescribed pressure following a sleep study,
- the ease of use and noise level of the device,
- compatibility with CPAP masks (nasal, full face or pillow),
- the presence of an integrated or compatible humidifier,
- comfort features such as ramp pressure or exhalation pressure relief.
A medical prescription is essential to determine the right pressure and ensure treatment effectiveness.
Frequently asked questions about fixed CPAP
A fixed CPAP delivers the same pressure all night (the prescribed one). An Auto CPAP adjusts pressure breath by breath within a defined range. Fixed is simpler, more affordable and just as effective when your pressure need is stable. Auto offers more comfort when pressure varies with position, REM stage or fatigue.
Yes, perfectly, when pressure needs are stable through the night. Fixed CPAP is the historical first reference of CPAP therapy, used for 40 years with excellent results. Clinical studies show efficacy comparable to Auto on suitable profiles.
The AirSense 11 Elite is the global reference, with touchscreen and myAir app. The prisma SOFT focuses on quiet operation (made in Germany, ~26 dBA). The EcoStar is made in France, more affordable and robust. Want the safe global choice? AirSense 11 Elite. Want quiet European made? prisma SOFT. Want affordable French quality? EcoStar.
At VivaRespire, expect €260 for the SEFAM EcoStar (French entry-level), €419 for the Löwenstein prisma SOFT (German, quiet) and €520 for the ResMed AirSense 11 Elite (global reference). A fixed CPAP is typically €40-60 cheaper than its auto-adjusting equivalent.
Yes. CPAP is a class IIa medical device. In most European countries, purchase requires a prescription from a doctor (general practitioner, pulmonologist or sleep specialist) stating the pressure to be set in cmH₂O.
Your pressure is determined by titration: either in a sleep lab (polysomnography with manual adjustment), or via an Auto CPAP over a few weeks to identify the effective pressure (typically P95 or P90 — pressure reached 95% or 90% of the time). The doctor then writes that value on your prescription.
No. A fixed CPAP lacks the hardware (additional sensors, algorithm) to switch to auto mode. If your needs change and you require auto-adjustment, you'll need to buy a separate Auto CPAP. Good news: the fixed unit can stay as a backup or travel device.
The Belgian INAMI/RIZIV system does not work via purchase reimbursement but via convention: the approved sleep center provides the device on loan (you do not own it). VivaRespire is outside the convention: you buy your fixed CPAP and own it. To understand the difference, see CPAP reimbursement in Belgium.
