generated, submitted, and approved by the requestor. Once cleared, a new cycle of 2.8 years begins and the only source
for the previous data will be the hard-copy reports.
NOTE-Only the provider has access to clear the meter.
using the SmartFlex Feature in cpAp mode
Your SleepCube has a SmartFlex pressure relief feature to help make it easier for exhale against your prescribed pressure
by lowering the pressure slightly when you exhale. The pressure returns to your prescribed pressure during inhale to
maintain your therapy.
The SmartFlex menu is available in CPAP mode and is a sub-menu that allows you to control various functions of your
SleepCube. It is accessed by pressing the down button while "SmartFlex Menu" is shown on the Display.
SmartFlex pressure relief includes three settings for exhale relief; 1, 2, and 3. (1 is the least amount of relief, 3 is the most
amount of relief). Setting SmartFlex pressure relief to OFF turns the SmartFlex feature OFF.
The pressure waveform can also be adjusted independently for inhale and exhale to smooth the transition when SmartFlex
pressure relief is active. The pressure waveform settings are SmartFlex-i (IRnd) and SmartFlex-e (ERnd) with settings from
0 to 5 in steps of 1 (0 is the least amount of smoothing, 5 is the most amount of smoothing).
SmartFlex pressure relief can be operated Full Time or during the Delay Only. The display will show "FLX" in the top row of
the default screen (between CPAP pressure and Mode) while SmartFlex pressure relief is operating.
When SmartFlex pressure relief is turned on Full Time, the pressure relief operates at all times when you are breathing on
the device. When SmartFlex pressure relief is set to Delay Only, the pressure relief operates only during the Comfort Delay
period and turns off after the delay period is finished.
The device contains a SmartFlex disengagement feature. If a patient is experiencing a respiratory event while the CPAP is
in the relief pressure mode, after a limited time the CPAP will shift to the prescription pressure and remain at this pressure
until normal breathing resumes.

using the comfort Delay Feature

Your SleepCube has a comfort delay feature to help make it easier for you to fall asleep. The airflow will start at a low
pressure and then gradually ramp-up to the prescribed setting over the last few minutes of the specified delay time.
NOTE–When the delay comfort feature is activated, a message will flash on the display periodically, indicating the amount
of time remaining in the delay.
You can adjust the amount of time spent in comfort delay by using the advanced device controls. The Delay Time can be
adjusted from 0 to 45 minutes in 5-minute increments. Refer to page EN-21 for details.
NOTE–If you are unable to change the delay time, your provider has locked this setting. Refer to the keypad menu guide
on page EN-21 for details.
Comfort Delay Feature In Standard CPAP Mode
When you use the comfort delay feature while your device is operating in CPAP mode, the airflow you receive at the
beginning of your therapy is temporarily lowered to a pressure selected by your physician when the device was setup.
Press the delay button to activate the comfort delay feature. The airflow pressure will drop to the prescribed comfort delay
pressure.
The pressure will gently rise to the pressure prescribed for your therapy. You may repeat the comfort delay by pressing the
delay button again if you have not fallen asleep during the first use.
Comfort Delay Feature in Bilevel Mode
When you use the comfort delay feature while your SleepCube is operating in Bilevel mode, the airflow you receive at the
beginning of your therapy is the delay pressure prescribed by your physician when the device was setup. The airflow
pressure will start at the delay pressure and gradually rise to the prescription setting. In Bilevel mode, the IPAP and EPAP
pressures will gradually rise until they reach the prescription settings.
Comfort Delay Feature in AutoBilevel Mode
When you use the comfort delay feature while your SleepCube is operating in AutoBilevel mode, the airflow you receive at
the beginning of your therapy is the delay pressure prescribed by your physician when the device was setup. The airflow

EPAP pressures will gradually rise together until EPAP reaches the Min EPAP prescription settings.
