Löwenstein Prisma SMART Auto - Complete Guide 2025
The Löwenstein Prisma SMART Auto is a premium Auto CPAP from the German manufacturer Löwenstein Medical. Less in the spotlight than ResMed or Philips, it is nonetheless highly regarded by users requiring higher pressures and by healthcare professionals looking for robust, precise technology. This guide presents its exclusive technologies, indications and the differences with the Prisma Smart Max.
Löwenstein Medical: German excellence in ventilation
Löwenstein Medical is a German group founded in 1945, specialising in medical ventilation devices. Widely present in hospitals and intensive care units, it developed the Prisma range for sleep apnoea patients. The brand is recognised for the precision of its algorithms and the robustness of its devices.
Exclusive Technologies of the Prisma SMART Auto
SoftPAP
SoftPAP technology reduces delivered pressure during exhalation. Unlike EPR mode (ResMed) or Flex (Philips), SoftPAP adapts the pressure reduction to the patient's actual breathing effort, resulting in greater comfort - especially at higher therapeutic pressures (above 12 cmH₂O).
SensAwake
The SensAwake function detects nocturnal micro-arousals and automatically reduces pressure during transitions between sleep and wakefulness. This avoids the discomfort of excessive pressure when turning over or briefly waking, facilitating a quick return to sleep.
Who is the Prisma SMART Auto for?
- Patients requiring higher therapeutic pressures (above 12-14 cmH₂O), where expiratory comfort becomes critical
- People sensitive to nocturnal pressure variations
- Users who have tried other devices without success and want to explore a different technology
- Clinicians seeking a finely configurable device with advanced detection algorithms

Frequently asked questions about Loewenstein Prisma SMART Auto
Yes. Loewenstein Medical is a German manufacturer founded in 1945, present in hospitals and intensive care units across Europe. The brand is recognised for the precision of its algorithms and the mechanical robustness of its devices. The Prisma range equips many European sleep centres. Less known to the general public than ResMed or Philips, it offers an excellent alternative for demanding patients, especially those needing high pressures.
SoftPAP is Loewenstein's exclusive exhalation comfort technology. It reduces delivered pressure during exhalation to ease breathing out. Unlike ResMed's EPR or Philips' Flex modes that apply a fixed reduction, SoftPAP dynamically adapts the pressure drop to the patient's actual breathing effort. The benefit is especially marked at high therapeutic pressures above 12 cmH2O, where expiratory comfort becomes critical for compliance.
Yes, it is one of its strengths. The Prisma Smart Max covers the 4 to 25 cmH2O range, versus 4 to 20 for the standard Prisma SMART Auto and most competitors (AirSense 11 goes up to 20). This extended range is useful for very severe apnea or patients whose titration reveals needs above 20 cmH2O. The Smart Max also offers advanced therapy modes (ST, T, PC) for complex cases including central or mixed components.
The Prisma Smart uses a standard 22 mm connector compatible with virtually all CPAP masks on the market. You can pair it with ResMed masks (AirFit N20, F20, P10, F30), Fisher & Paykel (Evora, Vitera), Philips (DreamWear) and all generic masks. Loewenstein also offers its own mask range optimised for Prisma algorithms, but it is not mandatory. Broad compatibility remains one of the advantages of this brand.
Both devices are very quiet at standard pressure, around 26 to 28 dBA measured at 1 metre. The audible difference is minimal in most cases. The Prisma Smart stands out mainly through smaller noise variation during nighttime pressure adjustments, thanks to a finely regulated inertial turbine motor. For noise-sensitive patients or those with a light-sleeping partner, it is a notable asset.
The model can be prescribed under convention if the accredited sleep centre works with Loewenstein among its suppliers. But the INAMI convention is not a purchase reimbursement: the device remains the property of the centre, which chooses the assigned model based on its contracts. You cannot request a specific model. To own your Prisma Smart, out-of-convention direct purchase at VivaRespire remains the only option. See our page CPAP reimbursement in Belgium.
Yes, OSCAR (Open Source CPAP Analysis Reporter) supports the Prisma Smart in several versions. You extract the SD card from the device, insert it in your computer and OSCAR automatically reads the files. You can then see detailed residual AHI, leaks, pressure curves and respiratory events. Loewenstein also offers its official prismaTS software for professionals and prismaSTART for patients via Bluetooth.
