PR System One REMstar Auto CPAP Machine with A-Flex

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.

Advanced Event Detection

The PR Auto CPAP is designed to identify symptoms beyond classic OSA parameters such AHI, flow limitation, Hypopnea, Obstructive and Central Apnea. With the PR system, detection is expand to include data on Snoring, Periodic Breathing and Respiratory Effort-Related Arousals (RERAs).

RERAs differ from a Hypopnea event in that a RERA shows increasing respiratory effort with each breath, culminating in a shift in brain wave activity and not necessarily a result of obstruction. Periodic breathing conditions such as Cheyne-Stokes respiration and central apneas are distinguishable from obstructed apnea or snoring events.

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. The PR Auto comes with both C-Flex and A-Flex modes as well as the new C-Flex Plus technology.

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+ minimizes the pressure transition and provides additional comfort when in fixed-CPAP mode. In addition, C-Flex+ softens the breathing cycle between inhalation to exhalation.

A-Flex is a comfort feature built on top of the REMstar Auto algorithm. If breathing events occur, the algorithm raises the A-Flex pressure profile to eliminate breathing events, while simultaneously making sure that pressure never rises to a level that's unnecessarily or uncomfortably high.

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.

Another PR System One Machine Option

Interested in a system that includes a heated hose? The PR System One REMStar 60 Series Auto CPAP with Heated Humidifier and Heated Tube comes with the same great features as the System One Auto featured on this page. However, the 60 Series Auto also offers an updated humidifier and adds a heated hose to the system to provide optimum humidification for comfort and effective therapy.
