BiLevel-ST therapy with adjustable target volume.

The prisma30ST is the device of choice for patients suffering from respiratory insufficiency, such as position-dependent hypoventilation and/or COPD, and simultaneously exhibiting sleep-related breathing disorders. A wide pressure range, various automatic functions as well as process and comfort-supporting features enable a safe, effective, and whisper-quiet BiLevel ST therapy made in Germany.

The advantages of prisma30ST.

Thanks to the unique autoS/T mode with adjustable target volume as well as autoEPAP and back-up rate, the prisma30ST offers comfortable ventilation, enabling rapid and sustainable successful therapeutic success. With a variety of ventilation modes and a wide pressure range of 4-30 hPa, individual therapy settings can be made, generating either natural or synchronous breathing as needed.

A target volume can be set between 300 ml and 2,000 ml on the prisma30ST. It is also possible to define SCOPES for indication-specific pre-settings and a quick therapy start, which makes the adjustment easier for the user.

In addition to the adjustable target volume, the prisma30ST also offers maximum BiLevel flexibility. The additional pressure relief (Bi soft 1/2), the automatically regulated pressure difference (autoPDIFF) and the autoTriLevel for additional and safe breathing comfort make this high level of flexibility possible.

The deep sleep and respiratory stability indicator prisma RECOVER continuously evaluates the breathing pattern during therapy and identifies phases of stable respiration. indicative of deep sleep, a particularly restorative phase of sleep. Even in BiLevel modes, phases of particularly stable respiration are also recognized and displayed. 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.

Product features

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.

Effortless and consistent application

The combination of a large screen (touch, LED) and intelligent menu navigation makes operation intuitive and fast. It's the ideal support for your various work processes.

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.
