Product Features


  • CPAP
  • APAP (autoCPAP)
  • 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 colour 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
  • Patient can connect to Prisma APP for checking therapy, generating reports and setting goals (when modem is connected)
  • Remote monitoring and setting of therapy parameters via Prisma CLOUD (when modem is connected)
  • 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, energised & fresh
