Lowenstein Prisma 25ST BiLevel (AUTO) S/T set with PrismaAQUA Humidifier & Heated Tube

The prisma25ST by Löwenstein Medical is the therapy device of choice at obstructive, mixed or complex sleep apnea with comorbidities. It offers its users maximum flexibility in BiLevel settings. Various automatic functions and comfort-enhancing features enable safe, effective and whisper-quiet BiLevel-ST therapy made in Germany.

The main features of the prisma25ST.

Whether it is maximum flexibility in settings or indication-specific pre-setting (SCOPES) - the prisma25ST by Löwenstein Medical offers you the right solution for your individual needs. The optionally adjustable automatic back-up frequency provides additional security.

BiLevel flexibility at its best.

Additional pressure relief (Bi soft 1/2), automatically regulated pressure difference (autoPDIFF) and autoTriLevel ensure maximum adaptability of the therapy to the patient's needs and provide additional, secure breathing comfort.

Features that impress.

The prisma25ST therapy device impresses with its intelligent BiLevel pressure profiles, the automatic or permanently set backup frequency and the integrated respiratory stability indicator prisma RECOVER. prisma RECOVER continuously evaluates the breathing pattern during therapy and identifies phases of very stable breathing that indicate deep sleep, a particularly restful phase of sleep. Even in BiLevel modes, phases of particularly stable respiration are recognized and identified. This means that, for the first time, successful therapy can also be evaluated in terms of sleep quality in prisma JOURNAL, prisma APP, prismaTS or in telemonitoring with prisma CLOUD.

Intelligent menu navigation.

The menu navigation of the prisma25ST sleep therapy device is identical to the other devices in the prismaLINE. This ensures quick, easy and intuitive handling and operation.

Sensorless intelligent humidification

When using the prismaAQUA humidifier, smartAQUAcontrol can optionally be switched on: to quickly warm up the applied flow at the start of therapy and to ensure humidifier performance during periods of increased leakage. prismaAQUA can optionally be operated with a heated circuit. 

Fall asleep comfortably - softSTART

The softSTART function can be activated to help you fall asleep and slowly acclimate to therapy pressure during the sleep phase. This ensures a slow increase in pressure over a set period until therapy pressure is reached. This is particularly useful for patients who find high pressure uncomfortable while awake and cannot fall asleep.

Pressure relief softPAP

For comfortable expiration during therapy, the pressure in CPAP and autoCPAP mode is reduced at the start of expiration and increased to therapy pressure in time for the start of the inhalation phase to facilitate exhalation as much as possible and effectively prevent events.

Pressure reaction fits patient’s needs

Patients react with varying sensitivity to pressure adjustments. For effective therapy and breathing comfort, two options for pressure adjustments are available in APAP mode. In addition, a pressure increases at closed central events is avoided.

Precise event recognition

With the help of “Forced Oscillation Technique” (FOT) in modes without back-up frequency or with “Forced Breath Technology” (FBT) in modes with backup frequency, reliably precise differentiation is made between central and obstructive apnea. Hypopnea too is reliably differentiated and recognized, as are other events such as Cheyne-Stokes respiration, flow limitations, snoring and RERA.

Please Note: This version does not include a celluar modem.The prisma APP is only available when the device has cellular connectivity.
