Getting treatment for sleep apnea isn't just about sleeping through the night. It's also about preventing serious health complications that can arise from never getting enough complete, restful sleep. Diabetes, anxiety and high blood pressure are among the various possible complications that can occur when people don't get treatment for sleep apnea. In some cases, apnea can even be fatal. Fortunately, there are ways for people to treat this condition. The most common form of sleep apnea treatment is with a CPAP machine, which works by creating a continuous stream of air into your airway while you sleep to keep the airway clear and unobstructed. Read on to learn about the three best models of CPAP machines for sleep apnea.
