    Product Overview

    Respironics brings "System One" to the new line of REMstar BiPAP machines. The PR BiPAP with Bi-Flex is an intelligent solution that knows when, why, and how changes should occur to consistently and effectively provide optimum sleep therapy. The PR BiPAP Auto is the leading edge of detection and response for the treatment of sleep apnea. Auto-Trak Sensitivity and new System One technologies, like Humidity Control with Dry Box and Resistance Control, all are helping users achieve effective therapy.

    Manufactured by Philips Respironics.

    Product Features

    The PR BiPAP Auto comes standard with carrying case, bag, memory card, manuals and now packaged with Respironics Performance Tubing.

    System One Humidity Control (Optional)

    The PR CPAP humidifier and water chamber are breakthroughs for managing rain-out and water damage. System One Humidity Control technology analyzes ambient temperature and patient airflow to reach relative humidity at the mask. Sensors inside and outside the BiPAP machine closely monitor changes in humidity and prevents condensation from forming inside the tube.

    Dry Box technology is another advancement in reducing water damage to BiPAPs. The air outlet port has been moved from the side of the humidifier onto the top. The water chamber is also outfitted with a one-way valve, between the machine and the humidifier. System One with Dry Box makes it possible for the PR BiPAP machines to be truly spill-free.

    System One Resistance Control

    Respironics wanted a machine to achieve optimal pressure regardless of whether the mask is nasal, pillow, or full face. Resistance Control is the solution. A numbering system on all of Respironics CPAP masks helps define the variable resistance characteristics. Each number programs the BiPAP to compensate for different mask types. The result? A consistent and reliable pressure, enhanced with all the benefits of Bi-Flex Technology no matter which mask is used.

    Bi-Flex Family Technology

    Flex Technology allows the PR BiPAP Auto to track each breath and provide pressure relief during three critical points in the breathing cycle. Pressure is reduced by half centimeter increments during the transition from exhalation to inhalation, inhalation to exhalation and during exhalation.The Bi-Flex setting can be adjusted up to 1.5cm of water pressure for maximum comfort.

    Advanced Event Detection and Response

    Digital Auto-Trak Sensitivity is the brains behind Respironics' Flex Technology. A patented algorithm monitors breathing patterns and responds to abnormal pressure changes. The Auto-Trak system measures variable triggers and cycle thresholds, adjusted pressure automatically to provide effective sleep therapy.

    The PR BiPAP Auto is designed to identify and respond to symptoms beyond classic OSA parameters such as AHI and flow limitations. With the PR system, detection is expanded to include data on Snoring, Periodic Breathing and Respiratory Effort-Related Arousals (RERAs). Along with digital Auto-Trak Sensitivity and Flex Technology, the PR BiPAP Auto can detect the breathing cycle and deliver comfortable pressures proactively.

    Advanced event detection and response includes:

    • Periodic Breathing
    • Clear airway apnea
    • Obstructed airway apnea
    • Hypopnea
    • RERA
    • Flow limitation
    • Vibratory snore
    • Large leak


    The PR BiPAP Auto not only detects these events, the REMstar Auto algorithm responds by automatically adjusting pressure levels to clear the apnea. Within a few seconds of recorded flow reduction, the PR BiPAP Auto pulses a series of pressures to determine if the apnea has been cleared. PR BiPAP Auto responses include:

    • Proactive Performance manages events in the early stages of flow limitation, which leads up to an actual obstruction or apnea. The Auto algorithm uses two airflow measurements to prevent pressures from becoming too high: ('P'ressure Critical and 'P' Optimal).

    • Leak Management is a comparison of average leak rate and the expected leak from a CPAP mask. Encore records significant losses above the expected leak rate as 'Large Leak' events and the BiPAP Auto reduces therapy pressure to re-establish the mask seal, preventing false apneas.

    • Obstructive Apnea is defined as events that reduce 80% of airflow for a minimum of 10 seconds.

    • Hypopnea is defined as events that reduce 40% of airflow for a minimum of 10 seconds.

    • Flow Limitation is measured through four different baselines of the breathing waveform: Roundness, Flatness, Peak, and Shape. Most other BiPAPs only take into account Flatness and Shape.

    • Snore or snoring can sometimes imitate a hypopnea event. Advanced detection allows the PR BiPAP Auto to measure vibrations and partial airway occlusions.

    • RERAs differ from a Hypopnea or snoring event in that a RERA shows increasing respiratory effort with each breath, culminating in a shift in brain wave activity and not necessarily a result of obstruction. Periodic breathing conditions such as Cheyne-Stokes respiration and central apneas are distinguishable from obstructed apnea or snoring events.

    • SmartRamp helps manage apnea events while users attempt to fall asleep. Unlike other BiPAPs, the PR BiPAP Auto can react to an event during Ramp Time.


    Encore Data Management and Reporting

    On-board memory has been added to the BiPAP as well as storing information on a generic SD Memory card and reads through any SD card reader. Use EncoreViewer Software to monitor therapy effectiveness through a series of reports. A new Patient Flow and Event report enables users to view a weekly breakdown on per-breath basis. Patient data is used to identify particular conditions and events with specific colors.

    CPAP Video & FAQ

    Frequently Asked Questions (FAQs)

    What does CPAP therapy do?
    CPAP therapy provides a constant airflow which holds the airway open so that uninterrupted breathing is maintained during sleep. It is traditionally provided through a nasal mask that seals around the nose to maintain the pressure level.
    Which CPAP masks work on which machines?

    Any mask will work with any machine, with one important exception. The ResMed AirMini is only compatible with certain ResMed CPAP masks. Compatible masks for the AirMini are as follows:

    • ResMed AirFit™ N20 Nasal Mask
    • ResMed AirFit™ F20 Full Face
    • ResMed AirTouch™ F20 Full Face
    • ResMed AirFit™ P10 Nasal Pillow

    When considering another CPAP, APAP or BiPAP machine from ResMed or any other manufacturer, mask compatibility extends to all brands. The AirMini uses non-standard tubing to connect the machine to the mask, and is the primary reason why other masks won't work with the AirMini. Despite this issue, many of our customers consider the AirMini to be an excellent machine.

    How do I choose the machine that is right for me?
    We provide our customers with many tools to make informed decisions about their machine purchases. Options include:

    What comes with my machine?
    Machines come with a six foot hose, power cord, at least one filter, and manuals. Most manufacturers include a carrying case which is designed specifically for their equipment. CPAP, APAP, and BiPAP machines do not come with a delivery system or mask. CPAP masks must be purchased separately.

    To see the list of what specifically comes with each machine, you can Browse for a machine. Then on the product page, click the "Specs" tab to see a full list of what comes with the machine.

    Do all CPAPs use filters?
    Yes, all CPAPs use at least one filter that is usually a type of foam material and washable. Some CPAPs offer finer filtration with the addition of a disposable paper filter.

    Cleaning and changing filters is the only maintenance required for a CPAP machine.

    The filters are located at the back of the machine at the air intake.
    Are prescriptions required for mask, machine, humidifier, and Provent purchases?
    Yes. Federal law requires we have a valid prescription on file before we ship your mask, machine, humidifier, or Provent.

    What is exhalation relief?
    Exhalation relief is a comfort feature which reduces the air flow at the time of exhalation, making the breathing process more natural.

    The following are the different types of exhalation relief names by manufacturer.

    • Philips Respironics = C-Flex, C-Flex+, A-Flex and Bi-Flex
    • Resmed = EPR (Expiratory Pressure Relief)
    • 3B Medical = RESlex
    • Apex Medical = PVA (Pressure Variation Algorithm) Pressure Relief
    • Curative Medical = EUT (Expiratory Unloading Technology)
    • DeVilbiss = SmartFlex
    • Fisher & Paykel = SensAwake Technology
    • Human Design Medical = Z-Breathe
    • Somnetics = EZEX

    Here are some machines with an exhalation relief feature:

    Transcend Auto miniCPAP™ Machine with EZEX
    PR System One REMStar 60 Series Auto with Bluetooth
    AirSense™ 10 AutoSet CPAP Machine with HumidAir™ Heated Humidifier
    + See More
    What is Bi-Flex?
    Bi-Flex is a feature that makes breathing back against CPAP pressure easier to do. Bi-Flex pressure relief technology offers pressure relief at the transition from exhalation to inhalation, at the transition from inhalation to exhalation, and during exhalation to make BiPAP therapy more like natural breathing.

    Bi-Flex Easy Breathing Technology Visual Graph Bi-Flex Easy Breathing Technology Visual Graph

    Here are some machines with Bi-Flex:

    DreamStation BiPAP Auto Machine
    PR System One REMStar 60 Series BiPAP Auto with Bluetooth
    What is the difference between Bi-Flex and C-flex?
    C-Flex only works at the start of an exhale. Bi-Flex works during the transition from exhalation to inhalation, the transition from inhalation to exhalation and during exhalation.
    What maintenance is required on machines?
    The only care a CPAP, APAP or BiPAP machine requires is to clean or change the filters at the air intake. This keeps the internal parts from accumulating dust. Fine paper filters should be changed out every 30 days, or when they appear soiled. Foam washable filters should be rinsed with clear running water once a week, allowed to air dry, and reinserted.

    Here are some other suggested actions to care for your machine:
    • Keep the area around your machine clean by removing any dust from the area to improve the air quality delivered to your machine and to you.
    • Keep the air intake of the machine unblocked. Curtains, bedding, and papers can easily block the air intake of your machine, reducing the airflow.
    • If a humidifier is used with your therapy, do not pick up the machine with the humidifier attached. With most machines it is easy to spill water from the humidifier chamber into the machine causing damage. Manufacturer warranties are voided by water damage to the machine. To avoid this, remove the chamber from the humidifier and then remove the humidifier from the machine rather than transporting them together.
    • If a humidifier is used, empty the water from the chamber every morning. Accidents happen. If a family pet or family member moves the machine and humidifier with water in the chamber it is more likely that water could be spilled into your machine. Water damage to a machine voids the manufacturer warranty.
    What are the CPAP, BiPAP, Sleep Apnea, and Oxygen related HCPCS, CPT or billing codes?

    E1399 is Miscellaneous and is used for other CPAP and Oxygen items.
    What does a BiPAP Auto prescription need to say?
    A BiPAP Auto prescription must contain all of the following information:
    • One of the following words or phrases: "BiPAP", "BiLevel", "VPAP", "BiPAP Auto"
    • Your physician's contact information
    • Your physician's signature
    • The patient's full name

    Inspiration pressure (IPAP) and expiration pressure (EPAP) are not required for a BiPAP Auto prescription.

    Here are some of our top selling BiPAP Auto machines:

    What is ramp?
    The ramp button on a machine is a feature that allows for a gradual pressure build-up to your prescribed pressure. The feature is enjoyed by those with high pressures because it eases up to their pressure.
    What data capable machines are available?
    CPAP machines which record full data (such as AHI and leak info):


    AutoPAP ("Autotitrating CPAP" or "APAP") machines which record full data:


    BiLevel ("BiPAP") machines which record full data:


    CPAP Machines that only record compliance data (hours used) are:

    How do I change the pressure setting of my machine?
    When a physician orders a pressure change, or a patient moves to an area with a very different altitude and does not have an altitude compensating machine, there are a number of ways to ensure you are receiving CPAP therapy at the correct pressure.

    Sleep laboratories and sleep disorder centers may be willing to make this pressure change. Just call a local hospital or ask your physician to recommend a sleep lab. Be sure to take your prescription.

    A second way is to do it yourself. We sell manometers that are very portable, accurate, and simple to use. All the machines we sell come with instructions on how to set pressure to physician orders. Most patients have little trouble doing this themselves. If you need help we can talk you through the procedure. Contact us by phone at 1-800-356-5221.

    Gauge Manometer (for pressure measurements)

    Fisher and Paykel Water Column CPAP Manometer with HC325 Chamber

    A third option is to ship the machine to us with the new prescription. We will set it and ship it back.

    It is the law and good common sense to run all sleep disorder devices at the prescribed pressure. If you think your prescribed pressure is wrong, talk to your physician.
    How do I use a battery to operate my CPAP?
    All machines can connect to DC power. Some machines are configured to operate on DC Power and have a DC power outlet. Other machines require AC power and will need an Inverter that turns DC power to AC power.

    Having the proper equipment is the biggest key to successfully operating the machine from a battery. For example, if your machine does have a DC outlet and you want to run your machine from a marine battery, be sure to get the correct DC cable for the machine, as well as an adapter cable with alligator clips that fits over the cigarette lighter plug.

    CPAP.com sells complete battery kits with everything you need for many machines including the correct cables for those machines and batteries. You can see if there is a battery kit available for your machine Here. If you have questions about the specific power needs of your machine, review the 'Power' tab found on the machine's product page, or give us a call at 1-800-356-5221.
    Why might I prefer an APAP machine?
    Some CPAP users find it more pleasant to breathe with an APAP than with CPAP. The pressure delivered by an APAP machine automatically changes as needed to deliver the minimal pressure required to maintain the airway. The pressure delivered by a CPAP machine is set to a single pressure, the highest necessary to keep the airway open as determined during the sleep study. This is the case even when the higher pressure is needed only a fraction of the time.
    What does an APAP prescription need to say?
    An APAP prescription must contain all of the following information:
    • One of the following words or phrases: "APAP", "AutoPAP", "AutoSet", "Auto CPAP", "Auto Adjusting CPAP", "Self Adjusting CPAP", "CPAP" or "Continuous Positive Airway Pressure" or similar term.
    • Your physician's contact information
    • Your physician's signature
    • The patient's full name

    An APAP prescription may contain the following information:

    • Your pressure range (Optional, Not Required)
      • Example: 4-20 CM/H20
      • Example: 4-20
      • Example: 6-18 CM/H2O
      • Example: 6-18

    CPAP prescriptions are accepted for Auto Adjusting (APAP) machines.

    Here are some of our top selling APAP machines:

    Transcend Auto miniCPAP™ Machine with EZEX
    PR System One REMStar 60 Series Auto with Bluetooth
    AirSense™ 10 AutoSet CPAP Machine with HumidAir™ Heated Humidifier
    + See More
    How do I prepare for power outages with CPAP?
    There are a lot of back up battery choices out there that can give you peace of mind in case of a power outage. The Transcend Travel CPAP Machine has Battery Options available that can set up as a fail-over, back up battery. Review the 'Power' Tab on the machine page.

    CPAP.com sells Battery Packs to accompany your machine if an integrated battery is not available. Visit CPAPtalk for more advice specific to your needs, or view this past thread on the topic here.
