The Role of the Device Operating Under the Continuous Positive Airway Pressure in the Recovery Process of Cochlea

The principle of operation is to prevent the closure and the narrowing of the structures of the upper respiratory tract by applying positive pressure. The device consists of a mask that protects the nose and/or mouth, a tube that connects the mask to the monitor and a monitor that blows air into the tube. A pressure in the range of 4 to 20 cm water is applied, depending on the individual needs of the patient to keep the airway open. The use is considered to be effective when the patient uses it continuously for at least 4 hours at bedtime. Today's modern devices have memory cards for storing data on the regularity and time of use of the device during the night and the efficiency of the device itself. For therapy to be considered effective, the number of apneas and hypopneas must be less than 5 per hour of sleep.
