Prisma 25 ST
Bi Level-ST therapy with innovative setting concept (SCOPES)
Prisma 25ST. the BI Level-ST therapy device in the prisma lINE
Therapy
Many possibilities: Broad pressure range (4 — 25 hPa) and several adjustable parameters for greater flexibility in therapy settings
High level of safety: With the new automatic backup frequency PRIO S+ and high fixed setting of backup frequency
Proven: Optional TRILevel pressure curve and auto EEPAP regulation
Fast: SCOPES (indication-specific pre-settings) with the option of making adjustments at any time
Precise: Identification of periodic breathing, RERA, snoring, hypopnea, apnea and flow limitations
Reliable: Apnea differentiation with FOT (Forced Oscillation Technique)
For natural breathing: Optional autoTrigger (Trigger IN)
