FAQ's
What is sleep apnea?
The word "Apnea" in Greek means "without
breath." Shuteye.com defines sleep apnea as "a
condition characterized by temporary breathing interruptions."
There are two types of sleep apnea: obstructive and central.
Familydoctor.org defines obstructive sleep apnea as a
stoppage of breathing caused by something (tongue, tonsils
or uvula) blocking the air passageway. Obstructive sleep
apnea is the most common type of sleep apnea. The website
defines central sleep apnea as a stoppage in breathing
caused by signals in the brain being interrupted or before
they can reach the muscle or the signal isn't being transmitted
at all. Central sleep apnea is rare and probably present
with other neurological problems. Shuteye.com continues
to explain that the number of interruptions vary from
a dozen to hundreds of times per night. Typically these
periods of stopped breathing last longer than ten seconds.
The Mayo Clinic describes the following symptoms of sleep
apnea:
· Excessive daytime sleepiness
· Loud snoring (more common with obstructive sleep
apnea)
· observed incidents of breathing stopping during
sleep
· Awakening with a dry mouth or sore throat
· Difficulty staying asleep
· Shortness of breath (central sleep apnea)
The National Heart, Lung and Blood Institute give the
following causes or risk factors for sleep apnea:
· Throat muscles and tongue relax excessively
· Tonsils and adenoids are larger than normal
· Excessive weight. The additional tissue in the
throat makes it harder to keep the throat open.
· The bones in the head and neck are disproportionate
to the size of the mouth and throat.
Helpguide.org states there are a few different types of
treatment for sleep apnea. The most common, CPAP, is discussed
below in this FAQ and is safe and easy to use. Dental
appliances are also used to treat sleep apnea, but are
not as effective as CPAP and as uncomfortable side effects
such as soreness in the teeth or jaws. The dental appliances
can be divided into two categories oral appliances, which
are similar to mouth guards that athlete’s use,
and head devices that fit over the head and chin to reposition
the jaw. Surgery can be used in situations where it is
appropriate to increase the airway size, remove throat
tissue or reshape the jaw.
What is CPAP?
Sleepcompliance.com defines CPAP(continuous positive airway
pressure) as 'a type of therapy used to effectively treat
obstructive sleep apnea in which an air compressor forces
air through the nose and airway..." CPAP treatment
consists of three parts: the CPAP compressor, tubing
and a special CPAP mask or cannula (comparisons between
the different types of CPAP machines, CPAP masks and
tubing are located below in this FAQ). The CPAP machine
is essentially a quiet air compressor that continually
forces air thorough the tubing to the mask or cannula
(cannulas are small tubes that fit within the nose).
The continuous air pressure forces the airway to remain
open, which allows for normal breathing for the entire
night.
Difference between Bi-level and Auto CPAP machines:
Bi-level CPAP machines have two different settings,
one for inhalation and one for exhalation. Auto CPAP
machines automatically adjust to the resistance a patient's
breath gives and provides the appropriate amount of
pressure. While Bi-level CPAP machines will work without
problems, Auto CPAP machines provide maximum comfort.
What type of mask should I use?
There are three types of CPAP headgear: full-face masks,
nasal masks and nasal pillows. Full-face masks cover
both the nose and face. For patients who breathe through
their mouths or have sensitive nasal passages, a full-face
is the best solution. The disadvantages of full-face
masks are that they are bulky and it can be difficult
to find a good fit that doesn't leak air. Nasal masks
are similar to full-face masks, but only cover the nose.
Because nasal masks only cover the nose, they are less
bulky than full-face masks. The disadvantages of nasal
masks are that they don't cover the mouth and that some
people feel uncomfortable having their nose covered.
For patients who feel claustrophobic with masks, nasal
pillows are ideal. Nasal pillows are small tubes that
fit within the nose and have connectors on the ends,
so they fit securely within the nose. Of the three mask
options, nasal pillows have the least amount of bulk
and work well with heated humidifiers. Nasal pillows
are not recommended for people with sensitive nasal
passages because the pillows can be irritating. This
problem, for some, can be solved with a moisturizer
or lubricant, like KY Jelly.
Which type of mask you use depends on your individual
needs. If you breathe through your mouth, you will most
likely want a full-face mask. If the bulkiness of the
mask is uncomfortable for you, nasal pillows might be
appropriate. Note: It is important you talk with your
doctor about CPAP mask options before starting treatment.
Can you give me some tips about using my CPAP
machine?
Adjusting to the CPAP machine in the first month can
be difficult. Proper use of the CPAP machine can go
a long way to eliminating uncomfortable side effect.
The Sleep Foundation reports that most problems with
CPAP are mask related. Often CPAP masks are too tight
or loose. If the CPAP mask is too tight, you will feel
uncomfortable. If the mask is too loose, continuous
pressure isn't being applied and the treatment is not
working. For the proper fitting of the mask, adjust
the headstrap and pads until they fit snugly, but not
uncomfortably. You may also have to buy a smaller or
larger CPAP mask if the adjustments aren't enough. Another
mask-related problem is that you might feeling claustrophobic
wearing the CPAP mask. Both Metrohealth and the Sleep
Foundation recommends that the wearing the CPAP mask
while doing a task that requires attention, such as
reading or watching TV, for short periods of time. By
wearing the CPAP mask for short periods of time, patients
get accustomed to wearing the mask.
Probably the second-most common side effect of CPAP
treatment is the dry or congested nasal passages. There
are several solutions to this problem. One solution
is to use a CPAP machine that has a heated humidifier.
The heated humidifier, with the help of the CPAP machine,
blows wet, warm air through the nasal passages, which
helps keep them moist and comfortable. Another solution
offered by Metrohealth is to purchase a saline nasal
solution, which is essentially a mixture of salt and
water. Saline nasal solution can be purchased for a
low price at a local drug store. A final option would
be to use a nasal decongestant, although you will want
to consult with a physician before taking a decongestant
for an extended period of time.
The third most common problem with CPAP machines is
adjusting to the continuous pressure. The Hopedale Medical
Complex recommends using the CPAP's machine "ramp"
setting. The "ramp" setting allows users start
out with very little pressure with the machine gradually
increasing it until the optimal pressure level is achieved.
Consult with your physician about what ramp setting
is right for you. The method of adjusting the ramp setting
varies between CPAP machines; consult the owner's manual
or manufacturer for more information.
There are a few other things you can do to avoid CPAP
problems. The most important thing is to clean the tubing,
headgear and mask regularly. Bacteria grow in the tubing
over time, especially when used with a heated humidifier,
which can cause respiratory problems. Unclean headgear
and masks can also accumulate bacteria and cause infections.
Another important tip is to stay consistent and committed
to the CPAP treatment. If you don't stay consistent
with treatment, it will be more difficult to continue
because you have not gotten accustomed to mask and continuous
pressure. Finally, if you still have trouble, consult
your physician and get help from CPAP support forums,
such as Apneasupport.org or CPAP Talk.
What is a polysomnogram?
A polysomnogram is a sleep test usually conducted at
a sleep center or hospital. According to Central DuPage
hospital a polysomnogram measures: brain waves, eye
movement, chin muscle tone, heart rate, leg movements,
breath, breathing effort, oxygen level as well as audio
and video of the room. During the test sensors are placed
on parts of the body gather measurements. Polysomnograms
are used to help diagnose several disorders such as
hypersomnia, insomnia, narcolepsy and obstructive sleep
apnea. Your doctor will be able to tell you whether
a polysomnogram is appropriate for you.
If you do get a polysomnogram, do not take any sleeping
pills, alcohol or caffeinated beverages before the test
because they will throw off the accuracy of the polysomnogram.
When you start the polysomnogram sensors will be placed
over parts of the body to gather the necessary measurements.
Most people are able to sleep with the sensors on because
they're small and unobtrusive. The testing area is typically
set up as like a bedroom, so patients can feel comfortable.
Is my CPAP machine covered by my insurance company
or Medicare/Medicaid
CPAP machine coverage varies by plan, but many insurance
companies do cover the cost of the machine and necessary
parts such as CPAP masks and tubing. Usually the insurance
companies will require some proof of need, so it may
be necessary to take a polysomnogram or some other sleep
test to determine whether you have a sleep disorder.
Resmed, a CPAP machine manufacturer, states that Medicare
requires an AHI(see next question) of 15 or more per
hour. A patient may also qualify with an AHI of 5 if
there are documented symptoms of excessive daytime sleepiness,
impaired cognition, mood disorders, insomnia, hypertension,
ischemic heart disease or history of stroke. For more
information, consult your insurance/Medicare/Medicaid
representative. Vitality Medical does not bill insurance
companies, Medicaid or Medicare.
What is AHI?
Pulmonary Reviews reports that AHI stands for Apnea-Hypopnea
Index and it measures how many times breathing is disrupted.
Pulmonary Reviews notes that AHI can sometimes be misleading
because disruptive sleep may appear in the form of increased
blood pressure, rather than stopped breathing. Although
it is not a definitive measurement, it can be a good
indication that treatment is needed. An AHI measurement
of less than 10 can be considered normal. Measurements
between 10-20are in a "gray area" in which
it might indicate a sleep disorder. AHI measurements
of over 20 usually indicate some type of sleep disorder.
