Continuous Positive Airway Pressure (CPAP)

Continuous positive airway pressure (CPAP) is a treatment for obstructive sleep apnoea (OSA). In OSA your tongue is sucked against the back of your throat blocking the flow of air to your brain. This causes you to partially wake up – usually with a loud gasp – and clear the obstruction to restart the flow of air.

How it works

CPAP is usually offered to patients with moderate to severe sleep apnoea. You wear a mask over your nose and/or mouth during sleep. The mask is attached to a machine that delivers a continuous stream of compressed air. This helps to keep your airways open.

You will need to wear the CPAP mask every night for at least six hours (or as recommended by Dr Miller).

When used properly, CPAP is a highly effective way to treat OSA. Treating OSA can:

  • reduce your risk of heart problems such as heart failure
  • decrease daytime sleepiness
  • lower your blood pressure.
