There are a variety of devices and masks to choose from. A Continuous Positive Airway Pressure (CPAP) device blows air to the back of your throat at a constant pressure throughout the night. The pressure that you require to prevent apnoeas from occurring while you sleep will be identified by your physician or specialist through testing.
However, your doctor or LISA® specialist may recommend a different type of device. An Automatic Positive Airway Pressure (APAP) device adjusts pressure during the night and may vary the pressure from one night to the next. It actively responds to the continuous changes in your upper airway.
Bi-level devices are also available. These operate at two different pressure levels for easier exhalation. The higher level is applied during expiration and the lower level during inspiration. This device is generally used to treat obstructive, complex and central sleep apnoea.
Irrespective of the type, most devices have built-in humidifiers. If not, you can purchase these separately. Humidifiers add moisture and warm the air before you breathe it in – making your CPAP therapy even more comfortable.
You can rely on your LISA® specialist to guide you through the various options and help you find the device ideally suited to your needs.
