Most experts agree that there are simple steps you
can take in your every day life that can impact your
situation. The following suggestions, in concert with
your physician prescribed treatment may not rid you of
Apnea but can help you better cope with it:
Weight loss
Excess weight contributes to obstructive sleep apnea
in two ways: 1. Fat deposits in the neck tissue compress
the airway and make it more likely to collapse. 2.
Excess weight in the abdomen makes the breathing muscles
operate inefficiently, which contributes to breathing
difficulty when sleeping.
Weight loss by itself is very difficult (as many of
us know). Sometimes people are only able, or much better
able, to lose their excess weight after treatment for
sleep apnoea has begun, they are able to be more awake
and vigorous, and increase their energy use.
Smoking
As with the loss of excess weight, this is, of
course, just a good idea in general. However, quitting
might also help your sleep apnea in addition to its
countless other health benefits, by returning lung
capacity to normal. Try using the patch in your effort
to eliminate your smoking habit.
Alcohol
Eliminate alcohol in the evening. Alcohol depresses
your breathing reflexes and significantly worsens sleep
apnea.
Apnea sufferers should be very careful about
excessive drunkenness. It's possible that if you depress
your reflexes enough, you might not wake up at all. The
same thing goes for sleeping pills, drugs, or anything
that might affect your breathing.
Allergies and respiratory infections
These cause nasal congestion, which narrows the
airway and contributes to apnoea. Consult your physician
for medications to treat these which will not interfere
with sleep.
Medications:
Many common medications interfere with either the
breathing reflex or sleep or both. Some of the most
common are "sleeping pills", tranquilizers, and
short-acting beta blockers. Consult your sleep
specialist about seeking alternative medications. A list
of medications that affect breathing or sleep can be
found in "Snoring and Sleep Apnoea: Personal and Family
Guide to Diagnosis and Treatment," by Pascualy and Soest,
Demos Vermande Publishing: New York, 1995.
Breathing-assistance devices
Continuous Positive Airway Pressure (CPAP)
"Nasal CPAP" is the treatment of choice for most
people with obstructive and mixed apnoea. It is the most
reliable and effective treatment in most cases. Hundreds
of thousands of CPAP devices are now in use treating
obstructive sleep apnea.
It involves using a small air blower device connected
via a hose to a nose mask you wear while you sleep -
much like a regular oxygen mask, with straps to keep it
in place. Essentially, this devices blows air into your
nose to keep your airway from collapsing and creating an
obstruction by increasing the air pressure in your
airways. It isn't as unpleasant as it sounds - most
people get used to the sensation fairly quickly.
Admittedly, having to wear a face mask to bed isn't
the most attractive thing in the universe. All I can say
about that is: you have to live with it. Also, most bed
partners are usually happy to live with that rather than
snoring! And it is infintely preferable to the effects
of apnoea, both the fatigue and the other physical
effects (additional strain on the heart, &c.). The exact
results vary, but great many people report significant
changes in their lives when they start using CPAP - they
feel more awake, more alive - "like a whole different
person", in some cases.
Bi-Level Positive Airway Pressure
Bi-level positive airway pressure (BiPAP™ is one such
device) is a variation on CPAP. Instead of providing air
at a constant, steady pressure all night, the machines
"senses" how much air a person needs, based on
inspiration and expiration, and varies its level of
pressure accordingly. On inspiration, a higher pressure
is needed to prevent apneas, hypopneas, or snoring. But
on expiration the patient typically requires several
centimeters less of pressure.
What is the purpose of this? Well, some people find
that they simply cannot sleep with regular CPAP due to
the constant air pressure. Bi-level pressure helps this
problem by providing less pressure when you are
breathing out (exhaling) , and more when you are
breathing in (inspiring).
I would like to comment at this point that people
probably should not view bi-level pressure devices as a
cure-all if you're not happy with your current CPAP. I
suggest that you spend some time getting used to regular
CPAP. Don't give up on it because it feels weird for the
first few nights. One gets used to it after time. Just
because CPAP is annoying at first does not necessarily
mean you need bi-level pressure. Give it time.
Several manufacturers make bi-level airway pressure
devices. BiPAP™ is a trademark of Respironics.
Bi-level pressure devices are significantly more
expensive than regular CPAP, and I've heard that most
insurance companies will not pay for it unless your
doctor essentially demands it.
Responsive and "smart" airway pressure devices(JH)
In the belief that the reduction of total airway flow
would provide greater comfort to the patient and
encourage patients to use the airway pressure treatment
on a regular basis, several manufacturers have begun to
offer a new generation of treatment devices. These
devices incorporate flow and pressure sensors and
automatic regulation systems. There are three basic
approaches. One approach tries to keep overall pressure
requirements low by using high pressure only when there
is a specific problem, but this requires a very rapid
increase in pressure when a problem is detected. The
second approach (Horizon AutoAdjust™, Virtuoso™ )varies
the pressure delivered, providing less when problems are
absent, and raising the pressure gradually when problems
appear. The third approach (Sullivan AutoSet™) gradually
raises and lowers the pressure as conditions require,
but also changes the pressure within a specific breath
if an emerging problem is detected.
DPAP (demand positive airway pressure) uses a low
base pressure and rapidly ramps up the pressure after an
airway obstruction or flow limitation occurs. This rapid
ramp-up of pressure is used for each breath in which a
breathing problem is detected. This product is no longer
manufactured.
In the approach taken by several other manufacturers,
pressure changes are designed to be smooth and gradual,
although each device has unique characteristics. These
include: Horizon AutoAdjust™ by DeVilbiss, the Sullivan
AutoSet™ by ResMed, and the Virtuoso™ Smart CPAP system
by Respironics.
In the Horizon AutoAdjust™ by DeVilbiss, pressure
changes are designed to be gradual. Thus, in response to
airway obstructions or flow limitation, these devices
gradually increase pressure over a period of several
breaths until the problem is overcome. Then the devices
gradually reduce the pressure.
The Virtuoso™ Smart CPAP system by Respironics
monitors the airway for vibrations which typically
preceed apneas and responds by increasing pressure to
help prevent airway collapse. In the absence of such
vibrations, pressure is reduced.
The Sullivan AutoSet™ by ResMed uses flow information
to increase pressures rapidly enough to pre-empt an
emerging problem and thus prevent significant flow
limitation, while using a history of recent breaths to
gradually raise and lower overall pressures.
Devices like the Horizon AutoAdjust™, the Sullivan
AutoSet™, or the Virtuoso™ Smart CPAP system by
Respironics can be used in the laboratory or home to
titrate (determine) individual pressure requirements and
thus be used to determine the prescription for a CPAP
device. The professional doing the titration receives
extensive data on the patient, equivalent to a home
sleep study. The devices (sometimes in special
configurations for long-term home use may also be used
as an alternative to CPAP or bi-level airway pressure.)
Compared to CPAP, 'smart' devices may offer greater
patient comfort insofar as the overall pressure is
reduced, providing that the changes in pressure reduce
or eliminate apnea, snoring, or flow limitation, and
also provided that the changing pressures are tolerated
by the patient. They may be used for patients whose
pressure requirements may vary during the course of a
night, from night-to-night, and over longer periods of
time.
As professionals in the field of sleep disorders gain
experience with these devices and their appropriate
applications, they may provide an additional path to
relief for selected patients. As with any new form of
treatment, physicians and patients may need to review
studies of each device before selecting the one most
appropriate to the needs of the specific patient.
Clinical research on these devices is being presented
at professional meetings. In one study of treatment , a
comparison was made among three conditions: untreated;
treated based on professionaly determined pressure
settings applied to a manual or traditional CPAP; and
pressure determined by the 'smart' CPAP. Both the manual
and auto treatments reduced obstructions to breathing,
with the manual being more effective in reducing apneas
or hypopneas, but the auto system operated at a 35%
lower average airway pressure than manual CPAP.
Tongue-Restraining Devices (TRDs)
This is a suction cup that is gripped with the teeth
and which sucks the tongue forward, thus opening the
airway behind the tongue. People who snore only when
lying on their back, and whose tongue is the main source
of obstruction, sometimes find this device helpful.
Surgeries
Uvulopalatopharyngoplasty (UPPP) surgery
This surgery removes the uvula and tightens up the
soft tissue of the palate and upper throat (pharynx). It
can be done separately or in conjunction with other
treatments, depending on where in the airway the
obstructions occur. There are the usual surgical risks
involved with this surgery. Notable ones are general
anesthetic (depresses breathing reflex and can be risky
in people with breathing problems like sleep apnoea),
swelling of the airway, need for pre- and post-operative
medications (may depress the breathing reflex),
bleeding, and significant pain lasting up to several
weeks.
Is it effective? Will it free me from having to wear
a CPAP machine for life?
This surgery seems to have a history of being about
50% effective in about 50% of patients who have it. In
other words, many of the people who have UPPP will end
up having to use CPAP anyway. It is almost never a
"cure-all." In the author's personal opinion (and
remember: this is not medical advice!), the risks and
side effects of the surgery are usually not worth it.
No, I have not had it. However, I have yet to hear from
a person who was happy that they had the surgery, though
of course there probably are some. This is a decision
that each person has to make, but I advise you give it a
great deal of thought beforehand. Surgery is not
something to be undergone on a whim, and certainly not
for the sole (and somewhat vain, in my opinion) reason
of ridding yourself of the need for CPAP.
Laser-Assisted Uvulaplasty (LAUP)
LAUP is a relatively new laser surgery on the uvula
and soft palate that is reported to diminish snoring,
but no controlled studies have been done to show that it
reduces sleep apnoea. Because it is less extensive than
UPPP, it is unlikely to be any more effective than UPPP
in treating obstructive apnoea. It is usually done in
several steps, and is an outpatient procedure. For that
reason it is less risky than UPPP.
LAUP is a relatively new procedure, and there is
little data as yet concerning its effectiveness. Since
this procedure has been developed, it has been somewhat
heavily advertised as a "cure for snoring" in magazines
and newspapers. This is, in the author's personal
opinion, somewhat misleading and potentially dangerous.
While the procedure may sometimes be effective in
helping people who snore but do not have apnoea, the
main danger from LAUP is that people may eliminate their
snoring and assume that their problems are solved, when
in fact they may still have untreated sleep apnoea which
may continue to get worse but be ignored because its
primary alarm signal (snoring) has been silenced.
Potential patients should be careful that they don't see
an ad in the paper, call the doctor, and rush into a
LAUP procedure without research and consideration.
The American Sleep Disorders Association has
published standards of practice for LAUP. Their
recommendations are as follows:
"Because adequate peer-review objective data do not
exist regarding the effectiveness of LAUP for the
treatment of sleep-related breathing disorders,
including OSA [sleep apnoea], LAUP is not recommended
for the treatment of these disorders. [emphasis added]
Surgical condidates for LAUP as a treatment for
snoring should undergo preoperative clinical evaluations
that include an objective measure of respiration during
sleep. Asignificant number of patients who present with
a symptom of snoring will have underlying, undetected,
sleep-related breathing disorders.
Patients should be informed that the risks, benefits
and complications of LAUP have not been established.
Patients who elect to undergo LAUP for the treatment
of snoring may be at risk of incurring a delay in the
diagnosis of OSA, may be obviated by this surgical
procedure. Patients must be specifically informed of
this risk and should be evaluated on a biennial or
preferably, annual basis.
The perioperative use of narcotics may pose risks for
patients who have undergone LAUP operations; therefore,
careful clinical judgment should be used when
prescribing pain medications. Patients should avoid the
use of sedative medications, sleeping pills, and alcohol
during the perioperative period."

Nasal Surgery
May be done to open nasal passages, to correct a
deviated septum, or to improve the ability to use CPAP.
Jaw Surgeries
Several procedures have been used to enlarge the
lower and sometimes also the upper jaw, thereby
attempting to make more room for the airway. Which
patients will be helped by this type of surgery is not
yet predictable except in severe cases of facial
malformation, and only a few surgical teams have
extensive experience and have reported their results in
the medical literature. This probably should be
considered semi-experimental surgery.
