What are the Different Types of CPAP Machines?

CPAP machines are the most basic air pressure machine used to treat your sleep apnea.  Like all other machines this post will cover, this therapy works by delivering pressurized air through your airway in order to keep it open while you sleep.  This helps to eliminate the instances of apneas, where your airway closes and you actually stop breathing.  CPAP machines have one pressure setting, prescribed by your doctor, that the machine will run on throughout the night.

BiPAP machines are considered a step up from traditional CPAP machines.  They are able to toggle between two separate pressure settings in order to provide more comfort for the user.  Typically, these pressure settings are set to an inhalation pressure and an exhalation pressure, offering a higher and lower setting respectively.  Many users report that they are more comfortable with this type of machine because it offers an easier time exhaling, making them more comfortable.

Auto-adjusting CPAP (APAP)

dreamstationAPAP machines are the most sophisticated form of CPAP treatment and are often reserved for patients with severe sleep apnea.  Unlike CPAP and BiPAP machines, these machines are able to automatically register the amount of pressure needed to keep your airway open, even adjusting breath by breath if necessary.  Because of this ability, these machines are even capable of adjusting your pressure based on your sleeping position, any weight gain or loss, or things like alcohol consumption that could effect how you are breathing.  

Final Thoughts
