What To Expect Before Using CPAP
Before your sleep specialist prescribes CPAP, you'll
likely have a
sleep
study called a
polysomnogram,
or PSG.
A PSG usually is done while you stay overnight at a
sleep center. This study records brain activity, eye movements, heart rate,
blood pressure, and other important data while you sleep.
What To Expect During a Polysomnogram
Your sleep specialist may suggest a split-night
sleep study. During the first half of the night, your sleep will be checked
without a CPAP machine. This will show whether you have
sleep
apnea and how severe it is.
If the PSG shows that you have sleep apnea, you may
use a CPAP machine during the second half of the split-night study. A
technician will help you select a CPAP mask that fits and is comfortable.
While you sleep, the technician checks the amount of
oxygen in your blood and whether your airways stay open. He or she adjusts the
flow of air through the mask to find the setting that's right for you. This
process is called CPAP titration.
In some cases, this isn't done all in the same
night. Some people need to go back to the sleep center for the CPAP titration
study. Your sleep specialist will decide which type of study is best for you
and leave instructions with the technician.
What To Expect After a Polysomnogram
Your sleep specialist will review the results from
your sleep study. If CPAP will benefit you, he or she will prescribe the type
of CPAP machine and the correct settings for you.
Most health insurance companies now cover CPAP
treatment. You may want to contact your health insurance provider to learn more
about this coverage.
Your sleep specialist may be able to refer you to a
local home equipment provider. The home equipment provider will use your
prescription to set up your CPAP machine. Ask your sleep specialist to
recommend a home equipment provider that has a lot of experience with CPAP.
It's important to continue to work with your sleep
specialist as you adjust to CPAP treatment. Talk to him or her about how to
handle followup questions. Your sleep specialist can answer some questions, but
your home equipment provider may need to address others.
Selecting a CPAP Machine and Mask
CPAP units come with many features designed to
improve fit and comfort. Your home equipment provider will help you select a
machine based on your prescription and the features that meet your needs.
You may be able to use the CPAP unit for a trial
period to make sure you're happy with your choice.
There are many types of CPAP masks. The fit of your
mask is important, not only for comfort, but also to keep air from leaking out.
A mask that fits will help maintain proper air pressure and keep your airways
open.
CPAP masks come in different shapes, sizes, and
materials. Some fit over your nose and mouth; others only cover your nose. Some
masks can be worn with eyeglasses. If you need oxygen, masks are available that
have room for an oxygen tube.
Nasal pillows may be used instead of a mask. Nasal
pillows are small, flexible, mushroom-shaped cones that fit into each
nostril.
Let your home equipment provider know whether your
sleep on your back, side, or stomach. Different types of plastic tubing connect
the mask to the CPAP machine. Some types may make it easier for you to sleep on
your side or stomach. |
