Respironics introduces "System One" and C-Flex Plus through a new line of CPAP machines. The PR Pro 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 Pro comes standard with carrying case, bag, memory card, manuals and now packaged with the Respironics Performance Tubing.

System One Humidity Control (optional)

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.

C-Flex Plus is a new enhancement added to PR Pro and Auto CPAP machines. Similar to C-Flex, the technology provides pressure relief during exhalation based on expiratory flow. C-Flex Plus minimizes the pressure transition and provides additional comfort when in fixed-CPAP mode. In addition, C-Flex Plus softens the breathing cycle between inhalation to exhalation.

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. 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.

Respironics listened to the CPAP community and removed the "blue light" LED. The PR was placed in a dark room and the new power light could barely be seen. No more insomnia from excess system lights. The only common parts shared with the M series is the Power Supply. The PR system comes with a separate, external power brick and allows the overall CPAP to stay compact.

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.
