CPAP will provide 1 level of air pressure stably and continuously during using.

Auto CPAP (also called APAP) can automatically increase/decrease air pressure depending on the level of apnea of the user. When the device detects an event occurring during sleep such as apnea, hypopnea, or snoring, the device will increase the air pressure to a level just enough to correct that event. When the event is over, the machine will decrease the air pressure to a low level for user comfort.

In each breath, the machine also has a feature to reduce the pressure of exhaled air, making it easier to exhale. The level of reduction is from 1 to 3 cmH2O. The machine will automatically detect and synchronize according to the user’s breathing rate.

Auto CPAP are suitable for most users, some are optimal for women, and some are compact and easy to carry.


BiPAP (also known as BiLevel ) will provide 2 levels of air pressure: a high-pressure level when inhaling and a low-pressure level when exhaling, helping to reduce the respiratory work for the user.

Auto BiPAP can automatically increase/decrease the therapeutic gas pressure depending on the degree of apnea, and support the decrease in expiratory air pressure from 1 – 10 cmH2O. The device also detects and synchronizes with the user’s breathing rate.

BiPAP are often used for people who need high levels of therapeutic air pressure or people who use CPAP that are not effective.
