How does a CPAP machine work?

A CPAP machine is a device that  generates a continuous stream of pressurized air that travels through an air filter into a flexible tube. This tube delivers purified air into a mask that’s sealed around your nose or mouth.

As you sleep, the airstream from the CPAP machine pushes against any blockages, opening your airways so your lungs receive plenty of oxygen.

Without anything obstructing this flow of oxygen, your breathing doesn’t pause. As a result, you don’t repeatedly wake up in order to resume breathing.

Pros of using a CPAP machine.

  • CPAP is the gold standard in treatment of moderate to severe sleep apnoea
  • improves your ability to sleep without waking up
  • lowers your risk of having a heart attack, stroke, or other cardiovascular event
  • helps lower your blood pressure
  • reduces daytime sleepiness
  • may reduce blood glucose and cholesterol level


Although a CPAP machine can help prevent breathing interruptions when you sleep, there are also drawbacks with this device. Some people stop using CPAP machines due to the side effects.

Cons of using a CPAP machine.

  • discomfort and difficulty falling asleep, especially in the beginning
  • a feeling of claustrophobia or anxiety
  • nasal congestion
  • dry mouth
  • nosebleeds
  • skin irritation or sores where the mask touches the face
  • a feeling of being bloated with air

Because of their drawbacks, CPAP devices don’t work for every person with sleep apnea, an oral appliance is a practical alternative on the advice of your doctor.
