prisma20A | Löwenstein
Details
Auto-CPAP Therapy with
Forced Oscillation Technology
The prisma20A is Löwenstein Medical's premium Auto-CPAP device for obstructive sleep apnea. Its unique FOT technology reliably distinguishes obstructive from central apnea events, automatically adjusting therapy pressure for each patient's individual needs — whisper-quiet, all night long.
Forced Oscillation Technology (FOT)
Reliably separates obstructive from central apnea — no unnecessary pressure increases.
CPAP & APAP Modes
Fixed or auto-adjusting pressure with Standard and Dynamic APAP options.
prisma RECOVER — Deep Sleep Indicator
Detects restorative deep sleep phases by analysing breathing patterns during therapy.
Large Colour Touch Display
Intuitive touchscreen navigation, consistent across the entire prismaLINE family.
Intelligent Pressure Regulation
Adapts therapy pressure breath by breath throughout the night.
Whisper-Quiet Operation
Near-silent therapy for undisturbed sleep — for the patient and their partner.
prisma CLOUD — Remote Management
Secure cloud-based therapy data access for clinicians and homecare providers. Monitor and adjust therapy remotely without an in-person visit.
prisma APP — Patient Companion
Patients can view their therapy data, track progress, and stay engaged with their treatment directly from their smartphone.
SD Card, LAN & External Modem
Multiple data transfer interfaces ensure flexibility for every clinical environment — from home setups to full hospital integration.
prismaTS — Therapy Software
Comprehensive desktop software for detailed therapy analysis, session review, and reporting — designed for sleep medicine professionals.
PSG Interface
Direct PSG (polysomnography) interface allows seamless integration with sleep lab diagnostic systems for titration and data exchange.
Future-Proof & Compatible
Designed for long-term use with software and interface compatibility across the entire Löwenstein prismaLINE product ecosystem.
softPAP — Expiration Relief
Pressure is reduced at the start of expiration and raised again at inspiration — maximising comfort throughout the breathing cycle.
softSTART — Gradual Ramp-Up
Slowly increases pressure during sleep onset so patients can fall asleep comfortably before reaching full therapy pressure.
smartAQUAcontrol — Intelligent Humidification
Quickly warms applied flow at therapy start and maintains humidifier performance even during periods of increased mask leakage.
Heated Circuit Option (prismaAQUA)
Compatible with the prismaAQUA heated tube for consistent warmth and humidity from device to mask — reducing rainout and condensation.
Dynamic APAP Mode
For patients sensitive to pressure changes: Dynamic mode provides smooth, gradual adjustments rather than sudden shifts for a gentler experience.
All-Night Quiet Operation
Ultra-low noise design means therapy is virtually unnoticeable — protecting sleep quality for both patients and their bed partners.
Forced Oscillation Technology (FOT)
FOT is the defining intelligence behind the prisma20A. By superimposing small pressure oscillations onto the therapy flow, it continuously analyses airway resistance — enabling the device to reliably tell the difference between obstructive and central events in real time.
Obstructive vs. Central
Accurately classifies apnea type to avoid unnecessary pressure increases at closed central events.
Continuous Analysis
Real-time breath-by-breath assessment throughout the night for precise, always-current therapy.
Proven & Certified
Clinically validated technology, manufactured in Germany with full EU MDR compliance.

02 Technical Specifications
03 Usage & Medical Information
Indications for Use
Indicated for adult patients diagnosed with obstructive sleep apnea (OSA). Suitable for both home therapy and clinical environments. Therapy parameters must be set by a qualified sleep medicine professional.
Setup & Daily Use
Connect your prescribed mask to the device tubing. Use softSTART to ease into therapy at bedtime. Use nightly for at least 4 hours. Clean the mask interface and humidifier chamber regularly as described in the device manual.
Monitoring & Follow-up
Therapy data can be reviewed via SD card, prismaTS software, or prisma CLOUD for remote clinician access. Regular follow-up appointments are recommended to review the prisma RECOVER deep sleep data and optimise therapy settings.
