Continuous positive airway pressure (CPAP) is nearly always the first medical treatment for sleep apnea. CPAP is a machine that prevents your airways from closing during sleep.
CPAP can:
- Decrease daytime sleepiness. If you still feel sleepy during the day while using CPAP at night, tell your doctor.
- Lower daytime and nighttime blood pressure.
It may take time for you to be comfortable using CPAP. You may find that you want to take off the mask, or you may find it hard to sleep. If you can't get used to CPAP, talk to your doctor. You might be able to try another type of mask or make other adjustments.
Some CPAP devices automatically adjust air pressure or use different air pressures when you breathe in or out. They are easier and more comfortable for some people to use.
Sometimes medicine that helps you stay awake during the day may be used along with CPAP.
If you use CPAP, or another machine to help you breathe, you need to use it every night and while you nap. If you don't use it, your symptoms will return right away.
