C-Flex vs. Traditional CPAP: Brown University Study

Respironics has added their easy breathing CFLEX technology to the REMstar Auto. Now you can have both the comfort of auto-titrating pressure with the comfort of easy exhalation, all in one CPAP.

The Respironics REMstar Auto CPAP includes the following features:
  • Automatically adjusts pressure based on air-flow limitations from snoring, hypopnea or apnea events.
  • C-Flex technology offers a more comfortable way to deliver sleep therapy by giving pressure relief at exhalation. The amount the pressure is lowered is determined by one of three settings that you can adjust to your comfort.
  • Encore Pro SmartCard compatibility records compliance and session data.
  • Operates in Auto or CPAP mode.
  • Automatic start and stop operation.
  • Mask leak alert.
  • Automatic altitude compensation adjustment.
  • International power supply to operate on any AC current from 110 to 240 without adjustment to the machine. (An adapter may be needed to plug the CPAP into a wall outlet outside the US.)
  • Direct DC operation without the need for a DC/AC inverter, just a cable and adapter which are sold separately.
  • Two washable, reusable pollen filters are included, as well as one optional ultra-fine filter.
  • Two year manufacturer warranty against defects.

This system operates automatically between 110v and 240v AC. When traveling either inside or outside the USA, there are no switches to switch or fuses to change. The machine will automatically sense what voltage is needed and set itself to run on that power.

The user will need to adapt the plug that goes into the wall to fit the style of outlet socket that is being used. This is simply done with a Power Adapter Plug kit. This is the same type of plug adapter that would be used with a hair dryer or an electric shaver. World Traveler Power Adapter Plugs.

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.

Are prescriptions required for mask, machine, humidifier, and EPAP purchases?

Yes. Federal law requires we have a valid prescription on file before we ship your mask, machine, humidifier, or EPAP therapy, including Provent and Bongo RX. You will also need a prescription to purchase the Nightbalance POSA device.


We provide many easy ways to get your prescription:

  • We can request your prescription for you! When you checkout, just let us know you would like us to request your prescription, or you can log into your account to have us request your prescription.
  • Fax your prescription to our toll-free fax number: 866.353.2727, or our international fax number: 713.541.7377
  • Email your prescription to cpap@cpap.com
  • Upload your prescription in your account, under the Prescriptions Section
  • Ask your doctor to fill out our prescription form. We have both a standard prescription form and an EPAP prescription form.


For more information on prescriptions, please see our Prescription Section of the Learning Center.


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 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 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.
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
