Noise: In the old days, CPAP machines were clunky and loud. Instead of a whoosh, it was more of a WHOOSH. Some made metallic, clicking sounds.
But that was then. Machines today are smaller, quieter, and much less noticeable. Many brands are near-silent. That’s a bonus not only to CPAP users, but to their bed partners too.
Pressure: Machines have different air pressure settings. Some of them vary it depending on whether you’re inhaling or exhaling. Your doctor will help you figure out the level that’s comfortable for you and helps you the most.
Dryness: Some CPAP users say all that forced air dries out the nose and mouth. Many machines have humidifiers to fix that. Some even heat the moist air.
Trouble breathing through your nose: If you feel stuffed up from allergies, sinus problems, or a physical issue with your nose, you may have trouble using a CPAP machine. But the problem usually goes away when you treat your congestion, whether with medicine, allergy treatments, or sometimes surgery.
“A lot of people have nasal obstruction or congestion and they don’t even know it.” Parthasarathy says. Treatment for those problems makes CPAP work much better for them.
