Our prisma25S is the device of choice for patients with obstructive, mixed or complex sleep apnea who have high and/or fluctuating pressure needs and show poor CPAP compliance. It offers safe and effective therapy, thanks to adaptive pressure regulation across a broad pressure range, apnea differentiation by means of FOT and process-supporting features. All of that and more no louder than a soft whisper. Major features of prisma25S: Broad pressure range (4 - 25 hPa) and numerous parameters for greater flexibility with therapy settings Safe technology (FOT) distinguishes obstructive from central apnea High resolution therapy data for up to 14 days and detailed statistics for 366 days Very quiet even at high pressures Integrated tube heating prevents condensation in tube and mask
