CPAP stands for continuous positive airway pressure. Nasal CPAP therapy is a non-invasive, non-surgical way to treat obstructive sleep apnea.
What to Expect
When you come into the Sleep Center for a nasal CPAP, you will be fitted with a relatively small, comfortable mask that goes over the nose only. This mask is hooked up to a CPAP unit, which delivers an air pressure through the nose into the back of the airway to splint the airway open during sleep with air. Intially, the CPAP unit uses a low air pressure that allows you to breathe easily in and out against the slight pressure. When you’re asleep, the pressure is adjusted (titrated) to keep the back of the airway open during sleep. Pressure is titrated to keep you apnea-free in all stages of sleep and in all body positions. The CPAP allows you to achieve restful and deep sleep without interruption during the night.
Why It Is Done
This study is used to set the right air pressure for CPAP therapy in patients with obstructive sleep apnea (OSA).
