What Is A CPAP Machine?

A continuous positive airway pressure (CPAP) machine is a medical device that delivers air pressure into your airway passages (mouth and nose) to prevent them from collapsing while you sleep. The CPAP device delivers the air pressure through a tube and a mask that you strap over your nose and/or mouth, depending on the mask you need. CPAP equipment is used to treat severe snoring and sleep apnea, “Continuous positive airway pressure (CPAP)“, Accessed December 4, 2021

Sleep Apnea

If you are suffering from consistently poor sleep and you snore loudly, you may have a sleep disorder called sleep apnea. Sleep apnea is when your airway passages are obstructed during sleep, caused by the muscles surrounding them relaxing too much as you rest. This can make it impossible to get meaningful rest even when you are exhausted, and can cause symptoms such, “Sleep apnea“, Accessed December 4, 2021

  • Inability to breathe while asleep
  • Gasping for air while asleep
  • Dry mouth
  • Headaches
  • Insomnia
  • Excessive daytime sleepiness
  • Concentration issues
  • Irritable moods

Being unable to sleep properly, even if you get a full night’s rest, is a terrible condition to deal with. It makes everything in your daily life more difficult and puts you at risk for other medical conditions when your body cannot restore itself. Fortunately, if your sleep problems are caused by sleep apnea, Medicare will pay their share for a CPAP machine for your treatment.

Talk to your doctor about your sleep quality. If someone notices you snore rather loudly or if you frequently wake up while trying to sleep, your doctor may suggest you take an active approach to treat your condition with a CPAP machine.
