6. Leaky mask, skin irritation or pressure sores

A leaky mask or a mask that doesn't fit right means your CPAP machine can't deliver the correct air pressure. An air leak or a mask that doesn't fit well could irritate your skin. The mask also can direct air into your eyes, causing them to become dry or teary.

Try adjusting the mask's pads and straps to get a better fit. If the mask fits over your nose, make sure it doesn't sit too high on the bridge of your nose, which can cause air to blow into your eyes.

You may need to ask your CPAP supplier to help you find a different size or type of mask, particularly if your weight has changed a lot. Have your care team check your mask fit every year. Checking your mask for cracks, breaks or stiffness also can help you find possible leaks.

Tell your care team if you have skin irritation or sores. Petroleum-free skin moisturizers, mask wipes and CPAP mask liners can all help. Washing your mask and face daily can prevent infections and skin irritations. Ask your care team to show you the best way to clean your CPAP mask and machine.
