1. What Do CPAPs Do?
A CPAP device is a machine that helps treat sleep apnea. CPAP stands for “continuous positive airway pressure.” It raises the air pressure in your throat, so when you sleep at night, your airway stays open. This helps you breathe normally, sleep more soundly, and snore less — which could help your partner sleep better too.
2. CPAP Parts
CPAP systems have a small tank of water that raises the water content (humidity) of the air you breathe while you sleep. It connects to a filter, tube, and mask worn over your nose or mouth or both. Most masks have a chin strap to hold them in place while you snooze. Others have nose pillows that fit inside your nostrils.
