Debunking CPAP Myths — 10 Common Misconceptions an RRT Hears Every Day

Continuous Positive Airway Pressure (CPAP) therapy is a common and effective treatment for sleep apnea, a condition where breathing is interrupted during sleep. However, there are many myths and misconceptions about CPAP. Here are the most common ones, debunked by a licensed respiratory therapist.

Myth 1: CPAP is uncomfortable and difficult to use.

• Debunking: While it may take time to get used to wearing a mask during sleep, modern CPAP machines and masks are designed to be comfortable. There are many mask styles and sizes to suit individual preferences, and adjusting the straps and finding the right fit can significantly improve comfort. Browse masks and tubing or read the most common CPAP problems and solutions.

Myth 2: CPAP is only for severe cases of sleep apnea.

• Debunking: CPAP is commonly prescribed for moderate to severe sleep apnea, but it can also be beneficial for mild cases. Severity is determined by the number of apneas and hypopneas per hour. See how to read your sleep apnea test results.

Myth 3: CPAP cures sleep apnea.

• Debunking: CPAP is a management tool, not a cure. It keeps the airway open while you use it. Lifestyle changes, such as weight loss, positional therapy, and avoiding certain substances, may also be recommended. Learn about options in Beyond CPAP: new sleep apnea treatments.

Myth 4: CPAP is loud and disruptive.

• Debunking: Modern CPAP machines are designed to be quiet, and many models have noise levels comparable to a quiet whisper. Regular cleaning and filter replacement help keep noise down. See why your CPAP machine may be loud and how to fix it.

Myth 5: CPAP is only for older individuals.

• Debunking: Sleep apnea can affect people of all ages, and CPAP is suitable for both younger and older adults. The decision depends on severity and individual health factors, not age.

Myth 6: Once you start using CPAP, you can stop anytime.

• Debunking: CPAP is typically a long-term treatment. Stopping without consulting a healthcare professional can bring symptoms back. You cannot taper CPAP; you can stop only if a repeat sleep study shows your apnea is gone or controlled by another treatment. Read our full guide: How to Wean Off CPAP: Can You Safely Stop Using It?

It is essential for people with sleep apnea and their partners to talk openly with their healthcare providers about concerns, to improve comfort and long-term use. Need help? Book a CPAP Setup Education session with a licensed RRT, or see our CPAP FAQ.
