Continuous positive airway pressure (CPAP) therapy is a common treatment for obstructive sleep apnea. A CPAP machine uses a hose connected to a mask or nosepiece to deliver constant and steady air pressure to help you breathe while you sleep.

Common problems with CPAP include a leaky mask, trouble falling asleep, a stuffy nose and a dry mouth.

But if a CPAP mask or machine doesn't work for you, you have other options. And most CPAP masks can be adjusted to help make them more comfortable.

Here are 10 common CPAP problems and what you can do about them:

1. The wrong size or style CPAP mask

Work closely with your health care provider and the CPAP

supplier to make sure you have a CPAP mask that fits properly. People have different face shapes, so the right mask style and size for someone else may not work for you.

• Try a different mask. A range of CPAP masks is available. For example, some feature full face masks that cover your mouth and nose, with straps that stretch across your forehead and cheeks. These may make some people feel claustrophobic, but they work well if you prefer to breathe through your mouth during sleep. They also provide a stable fit if you move around a lot in your sleep.
