CPAP
A continuous positive airway pressure or CPAP machine is the most commonly prescribed device to treat sleep apnea problems. While you sleep, a CPAP machine continuously force compressed air into your mouth and nose. This helps you breathe correctly by keeping your airways open.
A CPAP machine's compressor (motor) produces a steady stream of pressured air that flows through an air filter and into a flexible tube. Purified air is delivered through this tube into a mask that is fitted over your mouth or nose.
The CPAP machine's airstream forces any blockages open as you sleep, allowing your lungs to get plenty of oxygen.
Your breathing doesn't slow down because there is nothing blocking this oxygen flow. You don't have to wake up constantly to start breathing again as a result.
