Feel and see the C-Flex difference.
It’s not hard to discover that C-Flex is a more comfortable
treatment for sleep apnea — you can feel the difference
with a quick demonstration. The difference is the C-Flex
waveform: a better way to deliver sleep therapy that
takes the work out of exhalation. You may also see a
difference in your patients who use C-Flex. Patients
simply feel better, and with good reason.
A study published in the June 2005 issue of Chest *
showed that patients using a REMstar Pro with C-Flex
used their therapy an average of 1.7 hours longer per
night than patients on CPAP after three months, and the
difference in adherence widened over time.
And to help you bring that promise of better results and
more comfortable therapy to more of your patients, we’ve
developed a family of REMstar devices with C-Flex so
you can match each of your patients to a device that fits
their needs.
The REMstar family gives you a choice of therapy modes,
reporting modes and humidification options to deliver a truly
tailored therapy solution to your patients. And now you have
even more choices to offer with the new REMstar Auto with
C-Flex and the REMstar Pro 2 with C-Flex.

How C-Flex works.
The difference that patients feel when using C-Flex comes, in large part, from Digital Auto-Trak ® . This patented algorithm precisely
identifies the transition between inhalation and exhalation – even in the presence of mask leak and other variables. Digital Auto-Trak
helps therapy feel more natural by matching therapy to the patient’s natural breathing pattern. And by matching the patient’s breathing
pattern, C-Flex can reduce pressure at the moment of expiration.
With three C-Flex levels, patients have the ability to select the level of pressure relief that’s right for them. The amount of pressure
relief will vary on a breath-by-breath basis depending on the patient’s expiratory flow and the C-Flex setting. The device returns to the
prescribed pressure at the end of exhalation to ensure proper therapy.

C-Flex setting = 1
C-Flex setting = 2
C-Flex setting = 3
The new REMstar Pro 2 with C-Flex, like all REMstar devices with C-Flex,
reduces therapy pressure right at the point that a patient begins to exhale.
The level of pressure relief will vary with every breath and can be increased
or decreased with one of three C-Flex settings to make therapy more
comfortable. And that can make long-term compliance easier to achieve.
REMstar ® Pro 2 with C-Flex
and REMstar Auto with C-Flex:
Two new ways for patients to
feel the difference.
To complete the family of REMstar devices with C-Flex,
we’ve added powerful new reporting features to the
REMstar Pro. Also, we’ve combined auto-titration with
C-Flex to introduce the REMstar Auto with C-Flex – the
most comfortable smart CPAP we’ve ever produced.
REMstar Pro 2 with C-Flex advances the ability of our
top-of-line sleep therapy system by adding the ability to
record apnea/hypopnea index, leak levels and snoring.
This gives you even more insight into a patient’s therapy
regimen – and makes it easier to identify any need to
modify therapy.
The REMstar Auto with C-Flex features a “multi-level”
algorithm that measures instances of flow limitation to
make systematic, subtle changes in pressure and assesses
the impact of these changes on the patient’s breathing
patterns. It can also determine how much of a response is
necessary to eliminate events and position the patients with
a more appropriate pressure – as well as compensate for
elevated leak levels and variable breathing.
Combining C-Flex and auto-titration makes the REMstar
Auto with C-Flex a particularly attractive device in a
sleep lab setting – especially when used in conjunction
with our Analog Output Module and Clinical Remote.

Breathing pattern recognition ensures the right therapy.
As impressive as the Proactive Algorithm therapy is, it would be useless without the Breathing Pattern Recognition ability of the
REMstar Auto with C-Flex. Breathing Pattern Recognition analyzes the shape curve of a patient’s airflow signal based on four
parameters (roundness, flatness, peak and shape). It can then seek out instances of flow limitation and respond accordingly –
either by cycling through the Pcrit, Popt and Ptherapy modes or by triggering the REMstar Auto’s secondary analysis.

The secondary analysis determines the occurrence
of breathing problems like apnea, hypopnea, snoring,
variable breathing and elevated leak levels based on
their effects on the patient’s airflow signal. Once it
detects one of these events, the secondary analysis
immediately begins to ramp up the pressure level to
a point that eliminates or compensates for the event.
REMstar Auto with C-Flex and the new REMstar Pro 2 with C-Flex come complete with Respironics’
Encore Pro SmartCard technology built in. This powerful tool allows you to handle patient files, develop
patient reports and track overall treatment progress of patient populations. Encore Pro’s true database
architecture unleashes its ability to manipulate and manage patient data. You can even compare the
wellness trends of different patients to explore ways to improve overall care based on different criteria
such as insurance provider or sleep lab.
The SmartCard records the date, time, ramp usage and duration of each session. Additionally, both
machines allow the SmartCard to record leak, apnea/hypopnea index and snoring – data previously
only available from the REMstar Auto with C-Flex. It can even be programmed to update the patient’s
prescription – when the programmed SmartCard is inserted, the prescription settings are automatically
transferred into the device – so, no in-home visit is required.

The Systems
The REMstar family of devices with C-Flex is your choice for designing
customized outcomes-based treatment plans for sleep apnea patients,
while helping you to meet your clinical and business goals. All systems
feature a sleek, updated design that includes backlit controls for the unit
and humidification system.
REMstar Plus with C-Flex
REMstar Plus with C-Flex offers optional integrated humidification,
lighted controls, an easy-to-read display and the revolutionary comfort
of C-Flex – all in a sleek design. This is the device that will redefine
the entry-level CPAP market.
REMstar Pro 2 with C-Flex
REMstar Pro 2 with C-Flex combines the amazing comfort of C-Flex and
optional integrated humidification with the power of Encore ®
Pro Data
Management Software. And now with the ability to record apnea/hypopnea
index, elevated leak levels and snoring, it’s the most versatile CPAP
we’ve ever offered.
REMstar Auto with C-Flex
The REMstar Auto with C-Flex is an ideal flow-based Smart CPAP for
use in the lab or home. Its Proactive Algorithm looks for and adjusts
to a patient’s needs based on optimal and critical pressure levels. And
the new Encore Pro software allows you to track events like snoring,
elevated leak levels and apnea/hypopnea. Add that to a host of other
great patient features, and it’s easy to see why REMstar Auto with
C-Flex is the smartest Smart CPAP we’ve ever made.
REMstar Heated Humidifier
Designed as an integrated addition to our REMstar family, this unique,
tubeless platform brings heated humidification to a new level. Its clear,
two-piece water chamber is easy to fill and is dishwasher safe. The
humidifier controls are on the CPAP unit, and the heated humidifier
plugs directly into the REMstar unit – so there is only one plug going
into the wall.
REMstar Integrated Pass-over Humidifier
This integrated pass-over humidifier’s revised design allows you to
choose unheated humidification without sacrificing the convenience
of the REMstar heated humidifier’s sleek, integrated design.
