The prisma25ST by Löwenstein Medical is an advanced BiLevel ST sleep and ventilation therapy device designed for patients who require controlled respiratory support. It is ideal for individuals with obstructive, mixed, or central sleep apnea, as well as patients with hypoventilation syndromes or neuromuscular and respiratory disorders. By combining spontaneous breathing support with a timed backup rate, prisma25ST ensures reliable ventilation even when spontaneous breathing is insufficient.
Equipped with a large, intuitive color touchscreen and user-friendly smart navigation, prisma25ST enables quick setup and effortless operation for both clinicians and patients. The device offers advanced pressure and ventilation control features such as adjustable backup rate, Ti control, softPAP pressure relief, and softSTART ramp, ensuring comfortable, synchronized, and effective therapy throughout the night.
Comprehensive monitoring and connectivity options — including SD card, LAN, and telemedicine compatibility via prisma CLOUD and prisma APP — allow seamless therapy tracking, data sharing, and remote clinical review. When combined with the prismaAQUA humidifier and optional heated breathing circuit, prisma25ST delivers warm, humidified airflow for enhanced patient comfort and long-term compliance.
