You use CPAP at home every night while you sleep. The CPAP machine will have one of the following:
- A mask that covers your nose and mouth.
- A mask that covers your nose only-called nasal continuous positive airway pressure, or NCPAP (this type of mask is most common).
- Prongs that fit into your nose.
WHAT TO EXPECT AFTER TREATMENT
It may take time for you to become comfortable with using CPAP. If you cannot get used to it, talk to your doctor. You might be able to try another type of mask or make other adjustments.
HOW WELL IT WORKS
Studies show that in people who have moderate to severe sleep apnea, nasal continuous positive airway pressure (NCPAP) lowers blood pressure during both the day and the night. CPAP is better than other non-surgical methods for treating obstructive sleep apnea. People with coronary artery disease who use CPAP for sleep apnea are less likely to have heart problems such as heart failure.
WHAT TO THINK ABOUT
When you are using CPAP, you need to see your doctor or sleep specialist regularly. You may also need more sleep studies to adjust the CPAP machine and check whether the treatment is working. The most common problem with CPAP is that people do not use the machine every night, or they take off the mask during the night because it becomes uncomfortable. Even one night of not using the machine can make you sleepy the next day.
