    REMstar Auto C-Flex CPAP Machine

    REMstar Auto C-Flex CPAP Machine

    The REMstar Auto with C-Flex is is an auto-adjusting CPAP machine which is set for a range of pressures, then seeks out and delivers the lowest level of pressure needed to keep the airway open. With C-Flex technology, not only with the pressure level vary as needed, but it will drop with each exhalation.

    The auto-adjusting CPAPs were designed for patients who are unable to participate in a sleep study or whose pressure needs vary during the night according to their stage of sleep or sleep position. However, any patient will receive very comfortable therapy from this type of CPAP.

    What maintenance is required on machines?
    The only care a CPAP 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.

    There 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 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.
    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. The image below shows the black foam filter at the back of the Everest 3 CPAP Machine.

    What is exhalation relief?
    Exhalation relief is a comfort which reduces the air flow at the time of exhalation, making the breathing process more natural. Philips Respironics and ResMed are the two manufacturers who offer exhalation relief features.
    • Philips Respironics = C-Flex, C-Flex+, A-Flex and Bi-Flex
    • Resmed = EPR (Expiratory Pressure Relief)
    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 they ease up to their pressure.
    What is C-Flex?
    C-Flex is a pressure relief feature that makes breathing back against CPAP pressure easier to do by reducing the pressure at the beginning of exhalation and returning to therapeutic pressure just before inhalation. Independent studies conducted by leading universities indicate that patient comfort, and therefore, patient CPAP compliance, is higher with machines that use C-Flex. C-Flex is a technology invented by Respironics, is proprietary, and is not available on other brands of CPAP machines.

    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.

    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.
    What does a CPAP prescription need to say?
    A CPAP prescription must contain all of the following information:
    • One of the following words or phrases: "CPAP" or "Continuous Positive Airway Pressure"
    • Your physician's contact information
    • Your physician's signature
    • The patient's full name
    • Your specific pressure setting:

      • Example: 9 CM/H2O
      • Example: 9
      • Example: 14 CM/H2O
      • Example: 14
    What is CPAP therapy?
    CPAP stands for Continuous Positive Airway Pressure. CPAP therapy is the most commonly recommended, and the most effective, treatment for obstructive sleep apnea.

    A CPAP machine provides air at a constant prescribed pressure. The air is delivered to the person through a tube and a CPAP mask. CPAP therapy provides a constant airflow which keeps the airway open so uninterrupted breathing is maintained during sleep. The air stream eliminates Sleep Apnea events and allows the person to get a restful sleep.

    The level of air pressure required to maintain your airway is determined during your sleep study. Your doctor will write a prescription for a CPAP machine set at that pressure.

    CPAP therapy is delivered through a nasal mask that seals around the nose or nasal pillows which seal at the nasal opening. Full face masks are available for a person who breathes through both the nose and mouth. Many innovative and comfortable options are available and advances in the delivery of CPAP therapy are continually occurring.

    For instance: Some machines offer a comfort feature such as FLEX or EPR technology. It provides exhalation relief, a slight drop in pressure at the time of exhalation to help make therapy more natural. APAP, BiPAP and BiLevel machines offer various levels of pressure throughout the night.
    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.
    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.
    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.
