One way to treat people who have sleep apnea is a continuous positive airway pressure (CPAP) device. A CPAP device includes a mask, tubes and a fan. It uses air pressure to push the tongue forward and open the throat thus allowing air to properly flow through. It reduces snoring and prevents apnea disturbances.You should put your CPAP device on whenever you sleep, even for naps. A CPAP device does not cure sleep apnea; but, when you use the device correctly, your sleep problems should get much better.
