BiLevel-ST Therapy with
Maximum Flexibility
BiLevel-ST device for complex sleep apnea with comorbidities. Backup frequency, SCOPES pre-settings, and full BiLevel flexibility — whisper-quiet, Made in Germany.
7 Modes: CPAP, APAP, S, S/T, T, autoS, autoS/T
Full BiLevel-ST coverage — from standard CPAP to fully automatic timed therapy.
Maximum BiLevel Flexibility
Bi soft 1/2, autoPDIFF, and autoTriLevel adapt therapy pressure to each patient's needs.
Backup Frequency — Auto or Fixed
0–35 bpm, auto or permanent — guaranteed breath delivery for complex cases.
FOT & FBT Event Detection
Dual detection tech reliably identifies OA, CA, hypopnea, Cheyne-Stokes, snoring, and RERA.
Large Colour Touch Display
Smart menu navigation shared across the full prismaLINE — fast, intuitive operation.
SCOPES Pre-Settings
Indication-specific pre-settings for a fast, accurate therapy start right out of the box.
smartAQUAcontrol Humidification
Sensorless intelligent humidification via prismaAQUA — rapid airflow warm-up at therapy start and stable performance during leakage periods.
Modern Connectivity: SD, PSG, LAN
Multiple interfaces for data transfer plus full telemedicine support — remote monitoring and remote settings via prisma CLOUD.
prisma RECOVER — Deep Sleep Indicator
Continuously evaluates breathing stability to identify deep, restorative sleep phases — unique therapy quality scoring in prisma JOURNAL, prismaTS, and prisma CLOUD.
softSTART & softPAP Comfort
Gradual pressure ramp at sleep onset plus expiratory pressure relief — making the transition into therapy natural and comfortable every night.
autoSTART / autoSTOP
Therapy starts automatically when breathing begins and stops when the mask is removed — completely hands-free nightly operation.
prisma APP & prisma CLOUD
Patient adherence app for daily motivation plus cloud platform enabling clinicians to review data and adjust settings remotely from anywhere.
Operating Pressure — prisma25ST
From standard CPAP therapy through to complex BiLevel-ST with backup, the prisma25ST covers the full pressure range needed for comorbid sleep apnea.
01 Key Features & Modes
- 7 Therapy Modes: CPAP, APAP, S, S/T, T, autoS, autoS/T — the most comprehensive mode set for BiLevel-ST therapy.
- BiLevel Flexibility: Bi soft 1/2 pressure relief, autoPDIFF automatic pressure differential, and autoTriLevel for additional breathing comfort.
- Backup Frequency: Auto or permanently set from 0–35 bpm — essential safety for complex sleep apnea with comorbidities.
- SCOPES: Indication-specific pre-settings for a fast, accurate therapy start aligned to the patient's clinical diagnosis.
- FOT & FBT Detection: Dual detection technologies for precise apnea differentiation in both non-backup and backup modes — identifies OA, CA, hypopnea, Cheyne-Stokes respiration, flow limitations, snoring, and RERA.
- prisma RECOVER: Deep sleep and respiratory stability indicator integrated into therapy quality scoring across prisma JOURNAL, prismaTS, and prisma CLOUD.
- softSTART: Gradual pressure ramp over a set period to ease patients into therapy at sleep onset.
- softPAP: Expiratory pressure relief reduces breathing effort and improves nightly compliance.
- autoSTART / autoSTOP: Automatic therapy management based on detected breathing — no manual controls needed.
- smartAQUAcontrol: Sensorless intelligent humidification with prismaAQUA — optional heated circuit available.
02 Technical Specifications
03 Usage & Medical Information
Indications for Use
For adult patients with obstructive, mixed, or complex sleep apnea — particularly those with comorbidities requiring BiLevel-ST therapy with a backup breathing rate. Suitable for home and clinical environments.
Setup & Daily Use
Your clinician will use SCOPES to apply indication-specific pre-settings before first use. Attach the prescribed mask to the device tubing, activate softSTART if needed, and allow the device to autoSTART when you put on your mask. Clean the mask and prismaAQUA humidifier chamber regularly per the device manual.
Monitoring & Remote Follow-up
Connect via SD, LAN, or modem module to prisma CLOUD for daily automated therapy data updates. Use prismaTS for detailed clinical analysis and remote settings adjustments. The prisma APP supports patient motivation and adherence between clinic visits.
04 Compatible Accessories
