Learn More About Your New Machine

The PR Plus CPAP machine is an intelligent solution that provides the highest level of comfort. New System One technologies like Humidity Control with Dry Box and Resistance Control for use with any mask, all are helping users achieve effective therapy. The PR Plus comes standard with carrying case, bag, memory card, manuals and now packaged with the Respironics Performance Tubing.

System One Humidity Control

The PR CPAP humidifier and water chamber design 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. Choose from 5 levels of relative humidity.

System One is the first humidifier in the industry which accounts for room humidity. Sensors inside and outside the CPAP machine closely monitor changes in humidity and prevents condensation from forming inside the tube.

Dry Box technology is another breakthrough in reducing water damage to the CPAP. Several unique designs are incorporated into the humidifier to prevent water from exiting the chamber. To start, the air outlet port has been moved from the side of the humidifier onto the top. This centers the entire delivery; minimizing the total water displacement around the hole. The water chamber is outfitted with one-way valve, between the machine and the humidifier. Any water that manages to escape the chamber gets trapped within the Dry Box, which acts as a reservoir for any water ingress past the valve.

System One and Dry Box Technology make it possible for the PR CPAP machines to be truly spill-free. This humidifier, even with a chamber filled to the "Full" indicator line, can be tilted, shaken, and even turned upside down without water leaking back into the device.

System One Resistance Control

Respironics wanted a machine to achieve optimal pressure no matter which mask is used. Resistance Control is the solution, a numbering system on all of Respironics CPAP masks based on variable resistance characteristics. Each number instructs the device to compensate for different mask types. The result? A consistent and reliable pressure enhanced with all the benefits of Flex Technology no matter which mask is used.

Flex Family Technology

Flex Technology is designed to enhance traditional CPAP therapy; maintaining effective therapy at minimal pressures. Users new to CPAP equipment find the Flex feature provides airflow at just the right pressure relief for every breath and makes adapting to CPAP therapy easier.

C-Flex offers a comfortable way to deliver sleep therapy by giving pressure relief at exhalation. Pressure is lowered based on a breath-per-breath analysis and provides up to 3 levels of relief based on the patient's expiratory flow.

Encore Data Management and Reporting

On-board memory has been added to the CPAP as well as storing information on a generic SD Memory card and reads through any SD card reader. This machine only tracks and shows compliance data through the on machine display or through the Encore Software.

Universal Power

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.

Universal 12 Volt DC Power Cord

This machine come 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. The machine can be powered by plugging the 12volt DC Power Cord into a cigarette lighter plug. This is ideal for traveling by car, boat, or recreational vehicle that is equipped with a cigarette lighter plug.

Weighing in at only 1.16 pounds the C-100 Battery is a terrific option for travel. Plus, the C-100 comes with a DC cable and connector peg suitable for use with the PR System One REMstar Plus CPAP Machine with C-Flex so no need to purchase a separate DC cable. This lithium ion battery meets UN Manual Test and Criteria requirements for travel. The C-100 Pack includes many accessories and a handy carry case designed to allow the the cords to be attached with the battery inside the case.

Respironics Battery Kit with Universal 12 Volt DC Cable

This portable battery pack is an external lead acid battery that is the ultimate in power, portability and convenience. This battery kit comes with the Respironics battery and the 12 Volt DC Power Cord (connects CPAP to cigarette lighter socket).
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.

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 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.

  • 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

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.

Haven't slept so well in years

Verified purchase | Oct. 13, 2012 | Verified CPAP.com Customer
With my last machine (PB GoodKnight 420) I was not getting enough pressure no matter how high I raised the settings. And, it never worked well with a humidifier (always felt like I was drowning). But, with my new PR, I can sleep through the night, comfortably, and wake in the morning without my sinuses being clogged. I no longer wake in the middle of the night gasping for air!

Replacement for "M-Series"

Verified purchase | Oct. 06, 2012 | Verified CPAP.com Customer
Great. I have been using a CPAP for about 5 1/2 years. This is quieter than my earlier M-Series. I use it about 7 to 8 hours a night. So far, so good.
