GIIS A20 / C20
- The G2S A20 / G2S C20 system is a CPAP (Continuous Positive Airway Pressure) device designed for the treatment of adult Obstructive Sleep Apnea (OSA) only, either in the hospital or at home.
- The device is to be used only on the instruction of a licensed health care professional. Your home care provider will make the correct pressure settings according to your health care professional’s prescription.
- Several accessories are available to make your OSA treatment with this device as convenient and comfortable as possible.
- To ensure that you receive the safe, effective therapy prescribed for you, use only BMC accessories.
- G2S C20 is a fixed pressure device with integrated humidifier and wireless connectivity.
- Manual P: The patented technology gives you the opportunity to adjust therapy pressure until you achieve your maximum comfort. Automatic leakage and altitude compensation ensure the therapy accuracy anywhere.
- Newly designed integrated humidifier has large heating plate (> 50 cm2), which ensures excellent humidifying capacity and improves comfort.
- With optimized noise reduction design, the noise level is as low as 28 dB, no matter static or dynamic noise, it is controlled to be the low-frequency noise which is imperceptible to human being, makes you feel it quieter.
- Reslex exhalation pressure release feature let you fall asleep at a lower pressure easily.
- Designed with integrated humidifier, RESmart G2S is smaller, lighter and more affable.
- 4-inch color screen with user friendly interface and 18-language.
- 3-button control panel, simple and easy to use.
- The water chamber with drawing structure and opening cover, is more convenient to fill water and clean.
- Easy data access: iCode and SD card records can be viewed and evaluate though RESmart PC software or PAP Link smart phone App.
Indicate the humidity level. There are five levels in total. The number of indicator lights that light up is directly proportional to the humidity level. If none of the indicator lights light up, it means the humidifier is turned off
Press this button to mute the alert. However, if the problem causing the alert is not solved, the alert will sound again two minutes later

The device delivers the following therapy:
- 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
- Auto – Delivers CPAP therapy and provides an air pressure no less than the prescribed one based on the patient’s needs.
- Apnea: A condition marked by the cessation of spontaneous breathing.
- Auto: Adjust CPAP pressure automatically to improve patient comfort based on monitoring of apnea and snoring events.
- Auto Off: When this feature is enabled, the device automatically discontinues therapy whenever the mask is removed.
- Auto On: With this feature, the device automatically initiates therapy when you breathe into the mask. This feature is always enabled.
- CPAP: Continuous Positive Airway Pressure.
- iCode: A feature that is intended to give access to compliance and therapy management information. The “iCode” consists of six separate codes displayed in the Patient Menu. iCode QR displays sequences of characters, and iCode QR + displays two-dimensional codes.
- LPM: Liters Per Minute.
- OSA: Obstructive Sleep Apnea.
- Patient Menu: The display mode in which you can change patient-adjustable device settings, such as the starting pressure for the Ramp feature.
- Ramp: A feature that may increase patient comfort when therapy is started. It can reduce pressure and then gradually increase the pressure to the prescription setting so the patient can fall asleep more comfortably.
- Reslex: A therapy feature that is enabled by your home care provider to provide pressure relief during exhalation.
- Standby State: The state of the device when power is applied but the airflow is turned off.
- min: Means the time unit “minute”.
- h: Means the time unit “hour”.
- yy mm dd / mm dd yy / dd mm yy: Means the date
