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.
1 Overview
1 Overview
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
1 Overview
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.
