6. Available Therapies
The device delivers the following therapies:
CPAP – Delivers Continuous Positive Airway Pressure; CPAP maintains a constant level of
pressure throughout the breathing cycle. If your health care professional has prescribed
ramp for you, you can press the Ramp Button to reduce the pressure and then
gradually increase the pressure to the therapeutic pressure setting so that you can fall asleep
more comfortably.
AutoCPAP – Delivers CPAP therapy and provides an air pressure no less than the prescribed
one based on the patient’s needs.
AutoS – A bi-level mode which responds to both your inhalation and exhalation. The
differential pressure of IPAP and EPAP are presetted by home care provider. While working in
auto feature, the device will automatically adjust the IPAP and EPAP if it detects a sleep
apnea.
S – A bi-level mode which responds to both your inhalation and exhalation by increasing
pressure when you start to inhale and decreasing pressure when you start to exhale. There is
no automatic delivery of a breath you do not inhale. IPAP (Inspiratory Positive Airway
Pressure) and EPAP (Expiratory Positive Airway Pressure) are preset by home care provider.
S/T – A bi-level mode which responds to both your inhalation and exhalation by increasing
pressure when you start to inhale and decreasing pressure when you start to exhale. If you
do not start inhaling within a set time, the device automatically starts inhalation. When the
device starts inhalation, it controls the time of inhalation and automatically decreases the
pressure for exhalation within a set time.
T – A bi-level mode which the device automatically starts inhalation and exhalation,
automatically controls the time of inhalation and that of exhalation according to the preset
parameter.

11.3 Connecting to Power
(1) Insert the plug of the power adapter into the DC Inlet on the back of the device;
(2) Connect the power cord to the power adapter;
(3) Plug the other end of the power cord into the power outlet.
Fig. 11-3
Note: The length of the power cord and power adapter is 1.5 m and 1.8 m respectively
without the function of preventing electromagnetic interference.
WARNINGS!
• The device is powered on for use when the power cord and power adapter is connected.
The Knob turns the blower On / Off.
• Use of the device at an AC voltage beyond the stated range (see Section 5 “AC Power
Consumption”) may damage the device or cause device failure.
• Connect to appropriate power for proper operation of the device.
CAUTION!
• Inspect the power cord often for any signs of damage. Replace a damaged cord immediately.

IMPORTANT TIPS!
• After interruption and restoration of the power supply, the device will restore its
pre-interruption working status automatically.
• To remove AC power, disconnect the power cord from the power outlet.
11.4 Connecting to Power Cord Locker
(1) Assemble the power cord locker to the device directed by the positioning groove.
Fig. 11-4
(2) Open the power cord locker, plug the power cord to the power supply, and press the
locker downward to fix the power cord into the power port.
Fig. 11-5
The function of the locker is to prevent the power cord falling off from the power port.
11.5 Assembling the Tube and Mask
(1) Connect one end of the tube to the air outlet of the main device, as shown in Fig. 11-6.

Fig. 11-6
(2) Connect the other end of the tube to the mask according to the user manual for the mask.
Wear the mask.
WARNINGS!
• If multiple persons are going to use the device (e.g., rental devices), a low-resistance, main
flow bacteria filter should be installed in-line between the device and tube. Pressures must
be verified by your home care provider when alternate or optional accessories are in place.
• If you are using a mask with a built-in exhalation port, connect the mask’s connector to the
tube.
• If you are using a mask with a separate exhalation port, connect the tube to the exhalation
port. Position the exhalation port so that the vented air is blowing away from your face.
Connect the mask’s connector to the exhalation port.
• If you are using a full-face mask (a mask covering both your mouth and nose), the mask
must be equipped with a safety (entrainment) valve.
• In order to minimize the risk of CO2rebreathing, the patient should observe the following
instructions:
- It is recommended to use the accompanying tube and mask provided by BMC.
- Do not wear the mask for more than a few minutes while the device is not operating.
- Use only masks with vent holes. Do not block or try to seal the vent holes in the exhalation
port.
CAUTION!
• When using the tube with a diameter of 15mm, set the tube of the Patient Menu to 15 mm
(see Section 14.2 “Options of the Patient Menu and Corresponding Descriptions”).
11.6 Using Oxygen with the Device
Oxygen may be added at the mask connection. Please observe the instructions listed below
when using oxygen with the device.
WARNINGS!
• Connect the oxygen tube to the oxygen inlet of the mask.
• The oxygen supply must comply with the local regulations for medical oxygen.
• Turn on the device before turning on the oxygen. Turn off the oxygen before turning off the

device. Explanation of Warning: When the device is turned off, but the oxygen flow still exists,
oxygen may accumulate within the device's enclosure and pose a fire hazard. Turning off the
oxygen before turning off the device will prevent oxygen accumulation in the device and
reduce the risk of fire. This warning applies to most devices.
• Oxygen supports combustion. Keep the device and the oxygen container away from heat,
open flames, any oily substances, or other sources of ignition. DO NOT smoke in the area
near BPAP System or the oxygen container.
• Sources of oxygen should be located more than 1 m from the device.
• When using oxygen with this system, a Pressure Valve must be placed in-line with the
patient circuit between the device and the oxygen source. The pressure valve helps prevent
the backflow of oxygen from the patient circuit into the device when the unit is off. Failure to
use the pressure valve could result in a fire hazard.
• Do not connect the device to an unregulated or high pressure oxygen source. The pressure
of oxygen source does not exceed the work pressure of the device.
