C-Flex vs. Traditional CPAP: Brown University Study

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

The REMstar Auto M Series 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 CFLEX 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.

The REMstar Auto M Series CPAP with REMstar Heated Humidifier 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. You can read more about C-Flex by clicking here:
    C-Flex Brochure
  • The component REMstar M Series Heated Humidifier integrates with the REMstar Auto M Series to become one unit with only one hose and one power cord.
  • Automatic start and stop operation.
  • Mask leak alert.

Power Options
Universal Power

The M Series Auto operates automatically between 110v – 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 the power needed.

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.

DC Power (Cigarette Lighter Adapter)

The M Series Auto comes equipped with a DC plug on the back of the unit. This allows the user to connect the CPAP to an external DC battery source.

Using a Respironics, 12volt DC Power Cord the Remstar Auto M Series can be powered by plugging into a cigarette lighter plug. This is ideal for traveling by car, boat, or recreational vehicle that is equipped with a cigarette lighter plug.

Respironics, 12volt DC Battery Adapter Cable

DC Power (Marine Deep Cycle Battery)

It is recommended that you use a 100 amp hour, 12v DC deep cycle marine battery for operating you CPAP machine when not connected to 110v AC /230v AC.

There are two cables needed to configure the M Series Auto with a Marine Deep Cycle Battery. They fit together to make a connection from the back of the M Series Remstar Auto to the battery clip terminals on the marine battery.

Here are the links to the cables needed to hook up to a marine style battery. Both cables are needed.

Respironics, 12volt DC Power Cord (to connect CPAP to cigarette lighter socket)

Respironics, 12volt DC Battery Adapter Cable (to connect to battery terminals)

Respironics Battery Pack

The Respironics Battery Pack has been a long standing favorite of our customer’s. It weighs in at 13lbs and can be carried easily with its shoulder strap.

This battery pack will give roughly 26 hours of use, depending on the cpap pressure setting. (Results may vary.)

Respironics Battery Pack

* The Respironics Battery Pack must be charged with shore power. This unit can be charged at voltages ranging from 115v – 230v.

Satisified with new machine and order   February 04, 2010

(4 out of 5) by Jane B, SD

"Just got my new M series Auto C-Pap with CFlex. Have had a Respronics machine for 9 years, decided I needed an upgrade with a better humidifier that was heated, after my recent testing, with adding more air flow. So far I'm satisfied with my new machine and it's definatly quieter than my old one."

"I have used this machine and it's prior model for several years with no problems. I purchased the smaller updated unit both because it was lighter (for traveling) and because I felt I needed a backup in case the other needed to be repaired (assuming it can be, and that Respironica will still be making the parts). I use my older unit at home and take the newer unit when traveling. I choose the Auto C-FLEX model with Humidifier because experience has taught me that I need these features to be comfortable. Auto C-FLEX (with ramping) is incredibly comfortable to use, providing effortless breathing, and changed my life from the very first night I began to use it. I had apnia so bad that I simply counld not stay awake during the day, and started to nod after only an hour behind toe wheel of a car. I snored so loudly that my wife started making me sleep in another room. Life was not good. By the way, I choose the nose gear (Puritan Bennet Breeze SleepGear with Large (Green) Nasal pillows. I have found this system the most comfortable for me, allowing almost unlimited movement at night on both sides, on my back (for the firse time in years), and on my stomach (head to the side of course). The standard hose has proven to be adaquate. The filters are great, especially the micro dust and pollen filter (clean air all the time. Breathing moist air, by the way has a surprising cooling effect on vary hot nights. I have found it valuable to carry an extension cord and one extra milti outlet plug when traveling to allow machine electrical connection to plugs far away from the bed. One final comment. I have found the DC connection capability of the machine to be invaluable when camping. I purchased the DC adaptor, and attached the machine to a Marine Battery rated at 150 amp hours. The machine consumes an average of 3 amp hours (18 amp hours consumed if you sleep a 6 hour night). I re-charge the battery with an inexpensive solar unit the size of a sun visoor and have kept the system going for 2 weeks when fishing. I carry distilled water (20 oz in a Sams Club bottle) and have not run out yet durig a trip - water evaporated slowly in the humidifier. Good product, easy breathing in and out, minimum discomfort. Thanks for the high quality engineering - that such a simple thing could make such a difference in my life at the price it is offered."
