The Continuous Positive Airway Pressure or CPAP is an effective treatment for obstructive sleep apnea. This is a sleep apnea machine that blows air with continuous pressure down your throat, when you sleep at night, and keeps the airways open.
A mask that fits over your nose is held in place with straps, and a motor blows the air. Apnea patients find that the CPAP machine improves sleep quality, reduces snoring and lowers blood pressure. As the quality of night time sleep improves, there is less tiredness during the day.
