Therapeutic flexibility in obstructive sleep apnea (OSA).

prisma20A - the Auto-CPAP from Löwenstein Medical's premium product line offers everything you need for successful sleep apnea therapy. Thanks to Forced Oscillation Technology (FOT), the device reliably distinguishes between obstructive and central apnea and automatically adjusts the pressure to meet the patient's needs. The prisma20A is highly adaptable, ensuring a safe, effective and whisper-quiet APAP therapy made in Germany.

The most important features at a glance.

The device reliably supports you during the night, ensuring a smooth therapy process. Among its features, the prisma20A in CPAP and APAP-mode stands out for its functional user interface with a large touch display and intelligent pressure regulation throughout the breathing cycle. The device includes a softPAP comfort feature, where the pressure is reduced at the beginning of expiration during therapy in CPAP and APAP-mode and raised again to therapy pressure at the beginning of inspiration, maximizing expiration comfort.

The smart menu navigation on the large touch screen ensures intuitive and quick use. Patients and healthcare staff alike benefit from the intuitive and user-friendly concept. Effortless and consistent across the entire prismaLINE device family.

Patients vary in sensitivity to pressure adjustments. For effective therapy and comfortable breathing, the APAP mode offers two pressure adjustment options: Standard and Dynamic. The therapy pressure automatically adjusts to the patient's needs during the night. This makes the device suitable for treating patients with obstructive sleep apnea and fluctuating pressure requirements. An additional mechanism prevents unnecessary pressure increases at closed central events.

The integrated deep sleep indicator, prisma RECOVER makes it possible to assess the quality of sleep. It continuously analyzes the respiratory pattern during therapy and detects phases of stable breathing that indicate deep sleep, a particularly restorative phase of sleep.

Product features

Modern connectivity

Compatible and future-proof. Various interfaces such as SD, PSG, LAN and external modem offer various options for data transfer. Our software solutions (e.g. prismaTS, prisma APP and prisma CLOUD) are available for simple, flexible and secure therapy support.

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.
