PR System One REMstar Pro CPAP AutoIQ Overview
AutoIQ technology takes the PR System One REMstar Pro CPAP Machine with C-Flex Plus to a smarter level. This feature offers up to 30 nights of auto adjusting capability, during which time the system works as an Auto CPAP delivering an adaptive pressure on a breath by breath basis. An Auto-Trial phase must be a minimum of 3 nights in length. After an initial Auto-Trial period as set the system switches to Auto-Check Phase and functions as a CPAP delivering the pressure that the patient was at or below 90% of the time. The Auto-Check Phase continuously verifies pressure requirements and makes adjustments after every 30 hours of use providing the user with more effective pressure levels over time.
Please note: This is not an Auto CPAP Machine. It functions as an Auto CPAP during Auto-Trial Phases and switches to CPAP mode during Auto-Check Phase.
NOTE: the Heated Humidifier is included in the price of this machine.
AutoIQ has two phases: Auto-Trial Phase and Auto-Check Phase.
Auto-Trial Phase monitors and adjusts pressure on a breath by breath basis for up to 30 nights. The goal of the Auto-Trial Phase is to use breathing pattern data to identify the ideal pressure needed. At the end of a trial period, the machine is automatically set to a pressure that the patient was at or below 90% of the time.
All 30 nights do not need to be used at one time. A minimum of 3 nights can be used to complete an Auto-Trial Phase. The remaining nights can be used at any time in the future.
Every time the Auto-Trial Phase is used, the machine will use the most recent Auto-Trial Phase data to set the ideal pressure.
Once an Auto-Trial Phase is complete, the AutoIQ mode transitions to Auto-Check Phase. Every 30 hours the machine checks if a pressure adjustment is needed based on breathing events.
If a pressure adjustment is needed, the machine will automatically adjust by 1 cm/H2O up or down. Every 30 hours the machine will continue to track and adapt pressure as needed in 1 cm/H20 increments, staying within an upper and lower limit of 3 cm/H2O of the original set pressure. If a pressure change is not needed, the machine will stay at the current pressure.
Here is an example of how the Auto-Check Phase works:
If the ideal pressure after the Auto-Trial Phase was 10 cm/H2O and after 30 hours of use Auto-Check Phase data indicated the pressure needed to be raised, the machine would automatically change the pressure to 11 cm/H2O. If the pressure needed to be lowered, the machine would automatically change to 9 cm/H2O. If no pressure adjustment was needed, the pressure would stay at 10 cm/H2O. The Auto-Check Phase would continue every 30 hours to monitor and adjust the pressure as needed. However, the pressure would not be raised or lowered more than 3 cm/H2O of the original pressure. Using the original pressure of 10cm/H2O, the machine would not be lowered past 7 cm/H2O and would not be raised past 13 cm/H2O.
If the machine is placed back into Auto-Trial Phase mode to determine a new ideal pressure, the Auto-Check Phase would monitor and change pressure as needed every 30 hours, staying within 3 cm/H2O of the new ideal pressure.
The machine does not need to be set on Auto-Check Phase. It can be placed on straight CPAP mode, where no pressure checks or adjustments are made.
What is the Respiratory Distress Index? The RDI is used to determine the severity of sleep apnea. The index value is determined based on the number of apneas, hypopneas, and respiratory event-related arousal (RERAs) that occur per hour of sleep.
Encore Data Management and Reporting
The PR System One monitors and tracks therapy progress. It uses a SD card to capture advanced data such as leak rate and AHI (Apnea/Hypopnea Index). This data can be accessed through the "Info" menu on the machine's display. The PR System One records and displays both 7 and 30 day data averages.
To view more detailed data and to monitor trends over time, the optional EncoreViewer Software can be used.
C-Flex Plus Technology
Flex Technology provides pressure relief for every breath to make breathing with a CPAP more natural. C-Flex Plus technology reduces the pressure during exhalation based on expiratory flow. It also softens the transition between inhalation and exhalation.
System One Resistance Control
To reach optimal pressure, Phillips Respironics developed System One Resistance Control. It is a numbering system that allows the CPAP device to recognize a mask that is used with treatment. It achieves accuracy and reliability by instructing the device to compensate for the specific mask type.
System One Humidity Control with Dry Box Technology (optional)
System One Humidity Control closely monitors humidity levels for potential rainout. Using internal and external sensors, the optimal relative humidity level is determined. If there is a large difference between the room temperature and the hose temperature, there is a greater chance for more moisture to form. System One Humidity Control analyzes ambient air temperature to determine whether moisture will form. Based on the air data, the machine adjusts humidity levels to reduce moisture in the CPAP tube.
Dry Box Technology has also been added to prevent water damage. The Dry Box acts as a reservoir, preventing humidifier water from entering the CPAP machine.

A CPAP machine provides air at a constant prescribed pressure. The air is delivered to the person through a tube and a CPAP mask. CPAP therapy provides a constant airflow which keeps the airway open so uninterrupted breathing is maintained during sleep. The air stream eliminates Sleep Apnea events and allows the person to get a restful sleep.
The level of air pressure required to maintain your airway is determined during your sleep study. Your doctor will write a prescription for a CPAP machine set at that pressure.
CPAP therapy is delivered through a nasal mask that seals around the nose, nasal pillows which seal at the nasal opening, or nasal prong masks that seal inside the nares. Full face masks are available for a person who breathes through both the nose and mouth. Many innovative and comfortable options are available and advances in the delivery of CPAP therapy are continually occurring.
For instance: Some machines offer a comfort feature such as FLEX or EPR technology. It provides exhalation relief, a slight drop in pressure at the time of exhalation to help make therapy more natural. APAP, BiPAP and BiLevel machines offer various levels of pressure throughout the night.

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.

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.

All machines can connect to DC power. Some machines are configured to operate on DC Power and have a DC power outlet. Other machines require AC power and will need an Inverter that turns DC power to AC power.
Having the proper equipment is the biggest key to successfully operating the machine from a battery. For example, if your machine does have a DC outlet and you want to run your machine from a marine battery, be sure to get the correct DC cable for the machine, as well as an adapter cable with alligator clips that fits over the cigarette lighter plug.
CPAP.com sells complete battery kits with everything you need for many machines including the correct cables for those machines and batteries. If you have questions about the specific power needs of your machine, review the 'Power' tab found on the machine's product page, or give us a call at 1-800-356-5221.
Compliance software provides data such as patient hours, total machine operating hours, pressure setting, and pressure relief information. Advance software includes compliance data, as well as more detailed data such as AHI (Apnea/Hypopnea Index), leakage, average pressure, and a graphical representation of data.
Compliance software is available with some standard CPAP machines. Advanced software is available with most top of the line CPAP machines, APAP machines, and BiLevel machines.
First time using C Flex, but adjusted to it quickly. Good having the disc to send to my doctor to read. Ordering and shipping went smoothly. Have been a cpap user since 2005. more...

I have been using the REMstar Pro CPAP machine but not the IQ version, as a rental machine and liked it. I gave back the rental and purchased this one out of my pocket. I especially like the Auto IQ feature when I can titrate myself and reestablish the proper pressure what this machine does automatically. Well worth the price. An the service from CPAP.com is nothing short of Excellent as always. more...
