A continuous positive airway pressure device (CPAP) is used to treat people with sleep apnea. A CPAP is a device that uses a mask, tubes and fan to push the tongue away from the back of the throat and allows proper air flow. It will halt all occurrences of apnea and greatly reduce snoring. An individual with a CPAP device should wear it whenever they sleep, even for short naps. While a CPAP does not cure sleep apnea it will drastically improve your sleep problems.
