What is a CPAP machine How does the device work
                     What is a CPAP machine? How 
does the device work?
A continuous positive airway pressure machine CPAP is the equipment for treating 
obstructive sleep apnea. For those who aren’t aware, OSA refers to a sleep problem 
where the patient experiences difficulty breathing because of blockage. A CPAP device 
helps get rid of this blockage so you can sleep peacefully at night. Here is how this works!
How does a CPAP device work?
A CPAP machine consists of a tube and mask and helps people breathe. The device 
features a compressor that generates a continuous stream of pressurized air. This oxygen 
travels through the filter and reaches the flexible tube. Then, it delivers the purified air 
into the mask seal around your nose and mouth. During the process, the airstream pushes 
against the blockages and opens airways so oxygen can reach your lungs. Because of this, 
the breathing doesn’t pause at night, and the patient sleeps peacefully.
Are there many types of CPAP machines?
The CPAP machines feature the same basic components. They all have a motor, headgear frame, 
cushioned mask, elbow pieces acting as joints, tube connecting the mask and motor, and 
adjustable straps for fitting the device. 
However, here it needs to be noted that the types of masks vary to suit the needs of different 
patients. Which mask will fit an individual depends on his breathing habits, comfort, and the kind 
of sleep apnea he has. A few types of CPAP masks that sleep apnea patients must know about 
include,
Nasal pillow mask: 
This type of mask features a cushion that caps over the area of the nose and prongs that fit into 
the nostrils. It helps you wear glasses without interference. The mask is also suitable for people 
who have lots of facial hair as it prevents the mask from fitting snugly.
Nasal mask:
The mask is designed to cover the whole nose area and is a good option for 
people with a habit of moving around when sleeping. The mask delivers a 
high-pressure stream of air.
Full mask:
The CPAP mask is shaped like a triangle and covers the whole of your nose 
and mouth. Sleep experts prescribe this mask to patients who breathe 
through their mouths while sleeping. Also, it is a good fit for people with 
blockage in the nose.
What is the difference between CPAP and Bi-PAP machines?
People looking to buy CPAP device or Bi-PAP machines should be aware of 
the difference between the two:
A CPAP machine delivers a stream of air at a steady pressure level. To change 
the pressure, you will have to reset the device’s settings.
A BiPAP device features two pressure settings. One setting is for when you are 
inhaling air, while the other pressure setting is meant for exhaling. The 
machine is recommended for patients who cannot tolerate CPAP machines or 
have elevated levels of carbon dioxide in their blood. 
So, this is how the CPAP machine works.
