2. Meaning
• A continuous positive airway pressure (CPAP)
machine is the most commonly prescribed
device for treating sleep apnea disorders.
3. Fact about CPAP work
• Obstructive sleep apnea
(OSA) causes interruptions or
pauses in your breathing,
often because your throat or
airways briefly collapse or
something temporarily blocks
them.
• A CPAP machine sends a
steady flow of oxygen into
your nose and mouth as you
sleep. This keeps your airways
open and helps you breathe
normally.

6. CPAP machine work?
• A CPAP machine’s compressor (motor) 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.
7. CPAP devices all have the same basic
components:
• a motor housed in a base unit
• a cushioned mask
• a tube that connects the motor to the mask
• a headgear frame
• “elbow” pieces that act as joints
• adjustable straps that allow you to customize
the fit of the device
8. Different mask types
• Mask styles can vary with different CPAP
machines. Which type you wear depends in
part on your breathing habits, how
comfortable the mask is for you to wear, and
the kind of sleep apnea disorder you have.
9. The different types of CPAP masks
include the following:
• Nasal pillow mask. This type of mask has a small cushion
that caps over your nostril area. It may also have prongs
that fit into your nostrils. This mask allows you to wear your
glasses easily. It also works well if you have lots of facial
hair that may prevent a larger mask from fitting snugly.
• Nasal mask. This type is a cushioned mask that covers your
whole nose area. It may be a better option if you tend to
move around in your sleep. It can deliver a high-pressure
airstream.
• Full mask. This type is shaped like a triangle and covers
your mouth and nose. Your doctor might prescribe this kind
of mask if you breathe through your mouth when you sleep
or if you have a blockage of some kind in your nose.
10. What’s the difference between CPAP,
APAP, and BiPAP machines?
• Other types of breathing machines include APAP and
BiPAP devices. Here’s how they differ:
• CPAP device. This device is programmed to produce
pressurized air at one steady air pressure level. To
change the air pressure, you have to reset the device’s
settings.
• APAP (automatic positive airflow pressure)
machine. This kind checks your breathing throughout
the night. It automatically adjusts the air pressure to
compensate for changes in your sleep position or
medications that may have changed your breathing.
11. • BiPAP (Bi-level positive airflow pressure). This
device has two pressure settings, one pressure
for inhaling and a lower pressure for exhaling. It’s
used for individuals who can’t tolerate CPAP
machines or have elevated carbon dioxide levels
in their blood. BiPAP devices can also come with a
backup respiratory rate for patients who
have central sleep apnea. The backup respiratory
rate ensures the person breathes, as the main
problem with central sleep apnea is initiating
breath.
12. Advantages of use CPAP
• Pros of using a CPAP machine
• 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 levels
13. Disadvantages of use CPAP
• 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
