![]() In fixed CPAP, the pressure stays constant. You might also benefit from using a humidifier along with your CPAP system.ĬPAP may be given at a continuous (fixed) pressure or varied (autotitrating) pressure (APAP). If you're having particular difficulties tolerating pressure, some machines have special adaptive pressure functions to improve comfort. Several options are available, such as nasal masks, nasal pillows or face masks. You may need to try different types to find a suitable mask. However, newer machines are smaller and less noisy than older machines and there are a variety of mask designs for individual comfort.Īlso, with some practice, most people learn to adjust the mask to obtain a comfortable and secure fit. This air pressure prevents obstructive sleep apnea and snoring.Īlthough CPAP is the most consistently successful and most commonly used method of treating obstructive sleep apnea, some people find the mask cumbersome, uncomfortable or loud. With this treatment, the pressure of the air breathed is continuous, constant and somewhat greater than that of the surrounding air, which is just enough to keep your upper airway passages open. The most common type is called continuous positive airway pressure, or CPAP (SEE-pap). Positive airway pressure reduces the number of respiratory events that occur as you sleep, reduces daytime sleepiness and improves your quality of life. In this treatment, a machine delivers air pressure through a piece that fits into your nose or is placed over your nose and mouth while you sleep. If you have obstructive sleep apnea, you may benefit from positive airway pressure. This test usually involves measurement of airflow, breathing patterns and blood oxygen levels, and possibly limb movements and snoring intensity.Īn oral device is placed on the teeth and is designed to keep your throat open by holding your tongue and lower jaw forward. Under certain circumstances, your doctor may provide you with an at-home version of polysomnography to diagnose obstructive sleep apnea. This sleep study can also help look for other sleep disorders that can cause excessive daytime sleepiness but require different treatments, such as leg movements during sleep (periodic limb movements) or sudden bouts of sleep during the day (narcolepsy). If you're diagnosed with obstructive sleep apnea, staff may wake you and give you continuous positive airway pressure for the second half of the night. ![]() In a split-night sleep study, you'll be monitored during the first half of the night. You might be monitored all night, or part of the night in a split-night sleep study. During this sleep study, you're hooked up to equipment that monitors your heart, lung and brain activity, breathing patterns, arm and leg movements, and blood oxygen levels while you sleep. Tests to detect obstructive sleep apnea include: The evaluation might involve staying at a sleep center overnight to monitor your breathing and other body functions as you sleep. A sleep specialist can conduct additional evaluations to diagnose your condition, determine the severity of your condition and plan your treatment.
