This Philips Respironics BiPAP AutoSV with Humidifier is a certified refurbished model used for the treatment of central sleep apnea and Cheyne-Stokes respiration. This is the System One 50 series model number DS950HS. All product information for this model can be found below. Extended warranty options are available on refurbished CPAP and BiPAP Machines.

New Product Information Listed Below

The BiPAP autoSV Advanced System One device is intended to augment your breathing by supplying pressurized air through a circuit. It senses your breathing effort by monitoring airflow in the circuit and adjusts its output to assist in inhalation and exhalation. This therapy is known as Bi-level ventilation. Bi-level ventilation provides a higher pressure, known as IPAP (Inspiratory Positive Airway Pressure) when you inhale, and a lower pressure, known as EPAP (Expiratory Positive Airway Pressure), when you exhale. The higher pressure makes it easier for you to inhale, and the lower pressure makes it easier for you to exhale.

When prescribed, the device can also provide features to help make your therapy more comfortable. The ramp function allows you to lower the pressure when trying to fall asleep. The air pressure will gradually increase until the prescription pressure is reached. Additionally, the Bi-Flex comfort feature provides increased pressure relief during the expiratory phase of breathing.

Important Note: Every Certified Refurbished CPAP Machine comes with a 90 day limited warranty however, you can extend your warranty out to an entire year for ONLY $99.00!


Bi-Flex Comfort Feature

If enabled, the device provides a comfort feature called Bi-Flex. The Bi-Flex attribute adjusts therapy by inserting a small amount of pressure relief during the latter stages of inspiration and during active exhalation (the beginning part of exhalation). Bi-Flex levels of 1, 2, or 3 progressively reflect increased pressure relief that will take place at the end of inspiration and at the beginning of expiration.


If enabled, the device is equipped with a linear ramp function. The Ramp feature will reduce the pressure and then gradually increase (ramp) the pressure to the prescription pressure setting so patients can fall asleep more comfortably.

Rise Time Comfort Feature

If enabled, the device provides a comfort feature called Rise Time. Rise time is the amount of time it takes the device to change from the expiratory pressure setting to the inspiratory pressure setting. Rise time levels of 0, 1, 2, or 3 progressively reflect slowed response of the pressure increase that will take place at the beginning of inspiration. A setting of 0 is the fastest rise time while a setting of 3 is the slowest. Providers should adjust the rise time to find the most comfortable setting for the patient. Rise time cannot be adjusted when Bi-Flex is enabled.
