The special features of the prisma20C.

The prisma20C impresses with its modern and reliable design. In addition, the device features excellent blower technology for pressure regulation and remains pleasantly quiet even at high pressures.

Patient comfort is enhanced through various functions and modes. For example, softPAP pressure relief. This feature reduces pressure at the start of expiration and raises it back to the therapy pressure during the inspiration phase, facilitating expiration and prevent events. Additionally, the softSTART mode, characterized by a slow pressure increase over a preset time until therapy pressure is reached, supports falling asleep comfortably. This eases the adjustment to therapy pressure during the falling asleep phase.

Using Forced Oscillation Technique (FOT), the prisma20C can reliably distinguish between obstructive and central apneas. This allows the therapy to be tailored to the patient's needs and provides the treating physician with information for indication-appropriate therapy decisions. The algorithm not only distinguishes between apneas and hypopneas, but also displays other events such as Cheynes-Stokes breathing, flow limitations, snoring and RERA events.

The prisma20C is operated particularly quickly and intuitively thanks to the symbiosis of a large touch screen, user-friendly menu navigation and an intelligent user interface. This operating concept can be found on all prismaLINE devices, allowing for uncomplicated operation within the prismaLINE portfolio. Using the prismaTSlab software, remote adjustment is possible in the sleep laboratory, and it is also possible to set and read off the device remotely via prisma CLOUD.
