Prisma 25 ST

Bi Level-ST therapy with innovative setting concept (SCOPES)

Prisma 25ST. the BI Level-ST therapy device in the prisma lINE


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)
