The Prisma20A APAP (auto-CPAP) device, part of Löwenstein Medical's premium prismaLINE, meets all the requirements for effective OSA treatment. It features a functional operating panel with a large touch screen, a powerful motor with ample reserves, and intelligent pressure regulation throughout the respiratory cycle. Equipped with various comfort functions and the validated auto-CPAP algorithm incorporating Forced Oscillation Technique technology, the Prisma20A comes with a spacious 400ml click-into-place PrismaAQUA humidifier and a heated breathing tube.

With a design and functionality akin to the Prisma SMART, the Prisma20A offers the same reliable algorithm for proactive, efficient, and stable treatment. However, it boasts additional special features to enhance the user experience. These include a color touch screen, an integrated port for a heated tube, SoftPAP 3 setting with inspiration support and moderate expiration relief, seven humidification levels, Smart Aqua Control (SAC) for warm-up boost and humidification compensation during leakage, preheating capability for the humidifier, an alarm clock, language settings (different for patient and expert menus), independent autoSTART/STOP settings, and customizable alarms for leaks and disconnections.





Two algorithm settings (standard & dynamic) on APAP to best suit patient needs. Standard maximises patient acceptance through lowest possible pressures. Dynamic is more responsive to flow limitations for maximum numerical result and proactivity.


FOT to distinguish central from obstructive apnoea

Automatic needs-oriented pressure adjustment in phases of high pressure variability (APAP)

Compliance & Comfort:

Mask test ensures a comfortable and secure fit of the mask even at rising pressure levels during the night.

Qualitative leakage display during therapy

SoftPAP (Pressure Relief) with 3 levels: 1 (mild expiration relief), 2 (moderate expiration relief), 3 (moderate expiration relief and initial inspiration support)

AutoSTART & AutoSTOP as 2 independent functions depending on what suits the patient

Alarm clock function

Modern color touch screen (no blue light). This display is intuitive and easy to navigate.

400ml volume of PrismaAQUA humidifier requires less refilling. Issue-free heater rod with switch-off sensors to avoid overheating

Humidifier warm-up boost & humidification leak compensation via Smart Aqua Control (SAC)

Heated tube with an integrated port in the device to plug into – this particular tube provides pronounced warmth.

7 levels of humidification

Ability to preheat humidifier

Data Review:

Innovative Prisma RECOVER algorithm provides an estimated deep sleep indicator by analysing variability of respiratory minute volume

Patient can review usage, AHI & leakage on device (if enabled by clinician)

My Prisma Journal online platform for patient to track therapy including deep sleep

Convenient data and device management with PC-software prismaTS. Clearly presented extensive statistical data & detailed signal view available.

SD card to optimize work processes

Micro-USB cable connection to device as another option for work processes

Language can be adjusted between patient and clinician menus

Treatment Efficacy:

Advanced algorithm consistently achieves clinical efficacy (AHI<5/hr) with the following further clinical benefits (The Lowenstein Difference):

Prisma RECOVER – Innovative feature that estimates deep sleep.

High accuracy of AHI detection via FOT (Forced Oscillation Technique)

Proactive algorithm regulation

Dynamic & Standard Algorithm Options – see below

Stability of Pressure Adjustment – therapeutically effective with no unnecessary fluctuation

Efficiency of pressure – consistently low Pmax & Pmean

No compromise on clinical outcome with pressure relief SoftPAP

Less high pressures and fluctuations causing mask leakage & therefore less arousals independent of AHI, users report being able to wear mask looser

Users report increased motivation & productivity through waking up alert, energized & fresh.
