CPAP Questions

What is CPAP?

CPAP stands for Continuous Positive Airway Pressure. It is a machine that you use when sleeping to stop snoring and to correct other sleep apnea symptoms.

• How does it work?

CPAP delivers a constant flow of air through your nose. This constant air pressure prevents your airway from collapsing as your muscles relax with sleep, so that you maintain a steady oxygen level throughout the night.

• Can CPAP cure sleep apnea?

No. It does not cure sleep apnea, but it prevents you from suffering the symptoms.

• Do I need a prescription for CPAP?

Yes. The FDA requires that you have a prescription to purchase a CPAP unit.

• Are there different types of CPAP machines?

Yes, there are three basic types:

• CPAP – delivers one constant level of pressure
• APAP – starts out at a low pressure, senses when you are having a sleep apnea event and raises the pressure to accommodate
• BiPAP – uses a higher pressure when you inhale and lower pressure when you exhale

• Are there alternatives to CPAP?

Yes. Some patients are relieved from sleep apnea by a lifestyle or diet change. Others benefit from oral appliances that control the position of your jaw and/or tongue. People with severe sleep apnea sometimes require surgery.

• Do I have to use CPAP every night?

Yes. You only get the benefits of CPAP when you are actually using the device, so missing even one night can mean experiencing a sleep apnea event.

• What if I have to travel?

You can take your CPAP machine with you.
If you are flying, talk to the airline ahead of time. You should be able to carry your CPAP on the plane, and it should not count as one of your limited number of carry-on items. Do not check your CPAP machine into baggage, as it may be damaged.
If you plan to travel by car or enjoy camping, consider purchasing a CPAP unit which can run on batteries or plug into your cigarette lighter.

• Will my insurance cover CPAP?

That will depend on your individual policy, but most will cover CPAP. Sleep apnea has been linked to serious problems, so it is in your insurance company’s best interest to cover this preventative therapy.
