For patients with more complicated sleep disordered breathing (SDB), Philips Respironics offers the PR System One REMstar BiPAP Auto SV Advanced with Humidifier. The device features superb auto EPAP algorithm that monitors, automatically adjusts, and provides customized response to the unique inhalation and exhalation needs of each patient. The device also features the proprietary bi-flex technology that ensures patient comfort that leads to better compliance.

Optional System One Humidity Control

The unique PR System One Humidifier and Water Chamber present a superior design that prevents water damage using a one way valve, and an effective solution to rainout. The DryBox design reduces water seepage into the main device and ensures that vital electronics are always protected. The ergonomic design also puts the air outlet port on the top to prevent seepage and make access easier. The proprietary System One Humidity Control technology continuously assesses ambient temperature, humidity, and airflow, and automatically adjusts to provide the ideal humidity setting for the patient.

Optimal Pressures with System One Resistance Control

With the PR System One Resistance Control, you can use any mask and still be assured of excellent compatibility with the rest of the device. Philips Respironics System One Resistance Control employs variable resistance attributes, with an innovative numbering system on its masks. The assigned number then synchronizes with a program so that the device works in synchronicity with each mask type. This feature then ajusts to varying pressures in each mask to provide consistent and comfortable pressure.

Auto EPAP for Enhanced Therapy

The Auto EPAP feature tracks obstructed and clear airways by using an auto titrating algorithm. This allows the device to function similar to Auto CPAP or Auto BiPAP devices, and allows the system to recognize and adapt to changes in condition such as a change in medication or weight loss.

Advanced Back-up Rate to Encourage Spontaneous Breathing

Occasionally CPAP therapy may produce a side effect such as complex sleep apnea. The PR System One REMstar BiPAP Auto SV Advanced has an advanced back up rate that utilizes technology to ensure that the back up rate approzimates the natural breathing rate of the patient to stimulates normal spontaneous breathing.

Servo ventilation (SV) Algorithm for Smoother Breathing Patterns

With the SV algorithm, a smoother breathing pattern is obtained, utilizing pressure changes breath by breath and encouraging the correct breathing cycle. The device provides a target peak flow, to assist in regulating breathing patterns.

Bi-Flex technology

The Bi-Flex technology allows constant pressure relief, by monitoring breathing during three critical points in the breathing cycle. The device then reduces pressure in increments of half a centimeter while transitioning from exhalation and inhalation, and vice versa, as well as during exhalation. This enhances comfort and encourages a more natural breathing experience for the patient, which improves compliance to therapy. It can also be set up to 1.5 cm of water pressure for optimal comfort.
