Common Questions About CPAP Therapy

How does a CPAP machine work?

A CPAP machine generates a continuous stream of pressurized air that provides enough pressure so that your upper airway will not collapse and interrupt your breathing at night. The air generated from the machine travels through an air filter and a flexible tube and eventually into your mask. By keeping the airway open, the machine helps prevent the pauses in breathing that can wake you repeatedly during the night.

What should I expect when using a CPAP machine?

Using a CPAP machine is an ongoing process. In the first few days and even weeks, you might not feel comfortable using a CPAP machine and may even have a hard time falling asleep because the machine continuously delivers higher air pressure into your airway than you are used to. Over time, the goal is to get used to the therapy so that your sleep quality can improve. If you are struggling to get comfortable with your machine or mask, talk with your sleep provider about adjustments.

What does a CPAP machine cost?

The price of a CPAP machine varies by type, and machines with more advanced features usually cost more. The Sleep Foundation compares prices among different types of CPAP machines. Coverage varies by insurance plan, so check with your provider and insurer.

What is the life expectancy of a CPAP machine?

Depending on the type of machine, life expectancy can be different. A CPAP machine normally lasts for 3 to 5 years. However, there may be signs for you to replace your CPAP machine or its components. For example, if you’re experiencing loud noises or air leaks from your machine, you might need to talk to the manufacturer and replace certain parts or even the entire machine.

How often am I required to use my CPAP machine?

One study suggests that CPAP therapy needs to be used every night for the treatment to remain effective. If you stop using CPAP, your sleep apnea symptoms are likely to come back. In other words, CPAP treatment only works when you use it, so it’s important to make a long-term commitment to the treatment.

How long will I have to use CPAP therapy?

Some people feel better after the first few nights using a CPAP machine. Many people find that it takes a few weeks to get used to the therapy. Because symptoms are likely to return when CPAP is stopped, it is usually a long-term therapy. Your sleep provider can tell you what to expect and how to track your progress over time.

Do I need my CPAP while traveling?

Yes, because CPAP only works when you use it, so bring it with you on trips. The TSA allows CPAP machines on flights, and because a CPAP machine is a medical item, it generally does not count toward carry-on limits. Check with your airline before you travel. You can also choose a portable CPAP machine, which is smaller and more convenient to pack.

What are the benefits of using a CPAP machine?

Using a CPAP machine can help treat your sleep apnea and improve your sleep quality, and better sleep may also benefit your mood and your relationships. Read more about CPAP users and dating with confidence, and about the link between sleep and mental health.
