Details
BiLevel-S Therapy with
Maximum Flexibility
The prisma25S is the device of choice for patients with obstructive, mixed, or complex sleep apnea who require high or fluctuating pressure, or who have poor CPAP compliance. Advanced BiLevel modes, automatic functions, and comfort features ensure safe, effective, and whisper-quiet therapy.
Large Colour Touch Display
Big, vibrant touchscreen with intelligent menu navigation for fast, intuitive operation and at-a-glance therapy data.
4 Modes: CPAP, APAP, S, autoS
Full BiLevel-S flexibility with CPAP and APAP for standard therapy plus spontaneous and auto modes for complex cases.
Maximum BiLevel Flexibility
Bi soft 1/2 pressure relief, autoPDIFF automatic pressure differential, and autoTriLevel for clinically validated comfort.
Wide Pressure Range: 4–25 hPa
BiLevel pressure up to 25 hPa with apnea differentiation via Forced Oscillation Technique (FOT) for precise therapy control.
Adjustable Trigger & Ramp Speed
Settable inspiration ramp, trigger sensitivity at three levels, and pressure increase speed for personalised patient synchrony.
prisma RECOVER — Deep Sleep Indicator
Continuously analyses breathing patterns to detect deep, restorative sleep phases and report therapy quality scores.
smartAQUAcontrol Humidification
Intelligent humidification without extra sensors — quick warmth at therapy start with consistent performance even during leakage.
Modern Connectivity: SD, PSG, LAN
Multiple interfaces for data transfer plus telemedicine support via prisma CLOUD for remote monitoring and settings.
prisma APP & prisma CLOUD
Patient app for therapy motivation and adherence tracking plus cloud platform for clinicians to review and adjust settings remotely.
softSTART Sleep Onset Assist
Gradually ramps up to therapy pressure during sleep onset — ideal for patients who find high pressure uncomfortable at wakefulness.
softPAP Expiratory Pressure Relief
Reduces pressure at the start of exhalation and restores it before inhalation — making breathing feel natural and effortless.
autoSTART / autoSTOP
Device automatically starts therapy when breathing begins and stops when the mask is removed — zero manual interaction needed.
Operating Pressure — prisma25S
The prisma25S covers a broad pressure range to support standard OSA through to complex, high-pressure cases.

02 Technical Specifications
03 Usage & Medical Information
Indications for Use
For adult patients with obstructive, mixed, or complex sleep apnea — especially those with high or fluctuating pressure needs or poor CPAP compliance. Suitable for home and clinical use.
Setup & Daily Use
Attach prescribed mask to device tubing. Set mode and pressure as directed by your clinician. Use the softSTART function to ease into therapy pressure. Clean mask and prismaAQUA humidifier chamber regularly per the device manual.
Monitoring & Remote Follow-up
Connect via SD, LAN, or modem to prisma CLOUD for daily automated therapy data updates. Use prismaTS therapy software for detailed analysis and remote settings. The prisma APP supports patient adherence between clinic visits.
