1 Overview
1.1 Intended Use
The CPAP Ventilator is intended for the treatment of Obstructive Sleep Apnea (OSA) in patients
weighing over 30kg (66 lbs). It may be used in the home or hospital.
The CPAP Ventilator has two treatment modes: CPAP and APAP.
CPAP is suitable for the treatment of mild obstructive sleep apnea syndrome (OSAS).
APAP is suitable for the treatment of severe OSAS. In this mode, the device can automatically
adjust the pressure.
This device is a portable device for home use. It can be used only after completion of treatment
parameter settings under the instruction of a licensed physician.
The clinical manifestations of obstructive sleep apnea syndrome (OSAS) are mainly: snoring,
somnolent at day, sleep apneas, excessive urination at night, headache as well as other
complications.
1.2 Operation Theory
OSAS usually performs as airway obstruction, disturbance in respiration, which may cause
respective complications. The CPAP Ventilator uses dedicated air compressor to compress filtered
air from the surrounding environment to produce continuous positive pressure. The positive pressure
is transported to the patient through a breathing tube. The upper airway of the patient is kept open
under the positive pressure so that the patient can breathe normally. The working principle of the
CPAP Ventilator is illustrated by Figure 1-1.
Figure 1-1 Operation Theory
If the positive pressure is set to an excessively low value, the effect of treatment will be affected; if
the positive pressure is set to an excessively high value, the patient will feel uncomfortable.

1 Overview
2
Therefore, the patient must undergo pressure titration in hospital before using the CPAP Ventilator. A
licensed physician will present a report on usage pressure and perform pressure titration for the
patient.
The CPAP Ventilator is operated by using the display screen and control buttons on top of the
ventilator. The device functions are adjustable. The CPAP Ventilator is fitted with a heated humidifier,
which is used to increase the temperature and humidity of the breathed air so as to prevent mucosa
drying in nasal cavity and ensure comfort of the patient.
1.3 Warnings, Cautions and Contraindications

mask with the exhalation port.
b. Gently fit the mask onto your nose, adjust the mask, and gently tighten the four elastic
bands until you have a comfortable fit.
6. Connect to a power supply.
Connect the DC power plug of the power adapter to the DC power interface on the back of the
ventilator and connect theAC power plug to the AC power socket.
After power-on, the Home screen of the ventilator appears on the display screen (Figure 2-1).

The parameters on the user setup screen (press the button to enter the screen) can be set by
the patient. Other parameters must be set by a licensed physician or under the instruction of a
licensed physician.
3.1 Ramp Time
You can set ramp on the Home screen to increase the treatment comfort degree. (The ramp feature
is disabled by default.)
1. On the Home screen, rotate the control wheel to the RAMP menu and press the control wheel to
enter the RAMP screen (see Figure 3-1).
Figure 3-1 Setting the ramp time
2. Rotate the control wheel to select the ramp time and press the control wheel to confirm the
selection.
When the ramp feature is enabled, the ventilator outputs an initial pressure and slowly increases
the initial pressure to the therapeutic pressure during the predefined ramp time to help the
patient fall asleep. When the ramp time ends, the ventilator automatically detects the patient's
respiration conditions and adjusts pressure accordingly.
For details about the setting of the ramp time, see section 3.4.1 Detailed Treatment Settings.
3.2 Humidity Level
When the host is connected to the heated humidifier, you can set the humidity level for the warm-up
of the humidifier to ensure that the air output by the ventilator has a proper temperature when being
humidified.

The level of humidity can be set before or after cure. The value of Humidity Level ranges from 1
to 6, or it can be set to Off.
(When Humidity Level is not set to Off) Warming up or cooling down
Before starting treatment, press and held the control wheel for 3s. If the ventilator is not in
Warming Up or Cooling Down state, the temperature and humidity levels of the humidifier are
increased (see Figure 3-3). If the ventilator is in Warming Up state, the temperature and
humidity levels of the humidifier are reduced (see Figure 3-4).

Humidity Level is set to a proper value if small drops of condensed water exist inside the groove
of the tubing in the next morning. Humidity Level is set to an excessively large value if many
water droplets exist inside the tubing and mask; Humidity Level is set to an excessively low
value if you feel nose dryness; in these cases, reduce or increase the value of Humidity Level.
When you lie down, keep the ventilator slightly lower than your head so that drops of condensed
water flow back to the water tub of the humidifier to prevent respiratory impairment.
Empty water in the water tub of the humidifier when it is not used.
