About Sleep Studies
A sleep study involves spending at least one night at the Sleep Center.
You will enjoy a relaxing, private room in one of our bedroom laboratories.
For your comfort, these laboratories look much like your bedroom at home.
During your study, electrodes transmit and record your sleep patterns
and specific information about your physical activities, such as breathing,
brain waves, heart activity and eye and muscle movements, while you sleep.
The recording techniques are noninvasive (external) and all electrodes
are applied on the skin surface. The entire recording process is painless.
The recordings become data which is analyzed by Sleep Center physicians
and staff to determine the nature of your sleep disorder.
It is an over-night sleep study or Polysomnogram (PSG) is a special test
performed where electrodes and sensors are applied to record heart, muscle,
breathing, eye and brain function during sleep. These signals give the
doctor information about what is happening physiologically while you sleep
including the quality of your sleep, if you stop breathing periodically
during the night or move a lot. The sleep study is performed in a comfortable,
private room which looks just like a normal bedroom or hotel room. Patients
are monitored continuously by a certified sleep technologist.
Why Do I Need a Sleep Study?
A doctor may order a sleep study if they suspect a patient has a sleep
problem. Some medical conditions can interrupt your normal sleeping patterns,
without you even being aware of them. These medical conditions make it
difficult for you to reach the deep and restful state of sleep that you
need. As a result, you may never feel completely refreshed when you wake
up in the morning. Some common indications are:
- Having difficulty getting or staying asleep
- Finding yourself extremely tired during the day or cannot function normally
during the day
- You’ve ever been told you have pauses in your breathing or gasping
for breath while you sleep
- Morning headaches
- Your legs are “active” at night or leg jerks disturb your sleep
- Sleepiness and fatigue persist for more than two weeks
Types of Sleep Studies
Diagnostic – A diagnostic sleep study is done to determine if a patient has
a sleep disorder and if so, what type. During a diagnostic sleep study,
the electrodes and sensors are applied to see the whole picture of what
is happening physiologically while you sleep.
Positive Airway Pressure (PAP) Titration – A PAP titration is performed once it is determined a patient has
sleep apnea. PAP is applied using a comfortable mask and started on a
very low pressure. The pressure is increased to the point where the apneas
are resolved. There are different types of PAP and during the titration,
the technologist will determine the most effective modality and pressure.
During a PAP titration sleep study, the same electrodes and sensors that
are used in a diagnostic sleep study are applied as well as the PAP.
Split-night sleep study – A split-nigh sleep study consists of a diagnostic portion during
the first half of the night and a PAP titration during the last half.
Once it is determined that sleep apnea is present and certain criteria
are met, CPAP can be started. We try to do this whenever possible to prevent
a separate PAP titration study.
Home Sleep Test – Occasionally a sleep study can be done by wearing a device while
the patient sleeps at home. The device is picked up from the sleep center
where the patient is instructed on how to apply and use the device. The
device is returned the following day and the data is downloaded and analyzed
and a report is created. The Sleep Specialist will determine if a patient
is a candidate for this test instead of an in-lab sleep study.
Multiple Sleep Latency Test (MSLT) – An MSLT is a special sleep study performed to determine how sleepy
a patient is during the day. It consists of five naps throughout the day
to see how quickly the patient falls asleep. The MSLT is conducted after
a diagnostic sleep study.
Maintenance of Wakefulness Test (MWT) – an MWT is a daytime test used to measure how well a patient can
stay awake during the day. It is commonly performed for those patients
whose work depends on them being fully alert and awake during the day
such as pilots, bus drivers and heavy equipment operators.
Does My Insurance Pay For A Sleep Study?
Yes, most major health care insurance carriers pay for sleep studies, however,
patients should check with their insurance carrier for specific details.

Commonly Asked Questions:
Does It Hurt?
No. No part of the sleep study process is painful. The electrodes and sensors
are designed to be comfortable enough to be conducive to sleeping. Occasionally,
mild, short term skin irritation may occur where the sensors are attached
but the sensors do not normally cause any significant discomfort.
How Do I Get The Results?
Patients who have a sleep study will be scheduled for a follow up visit
with the Pulmonologist or Sleep doctor to get the results of their sleep
study usually within a week or two of their sleep study. It is important
to realize that if CPAP was started during your sleep study, which does
not necessarily mean you have sleep apnea and, if CPAP was not started
that you don’t have sleep apnea. There are many different circumstances
that occur during the sleep study but only the doctor can fully determine
if there is a sleep disorder and the appropriate treatment for it. The
sleep technologist cannot give results the morning following the sleep study.
What can I expect the night of my study?
On the night of your scheduled sleep study, you will be greeted by the
technologist. They will conduct a brief interview, provide an explanation
of the diagnostic procedure and answer any questions you may have concerning
your stay. We will then apply the sensors and give you time to acclimate
to your new surroundings. You will be in constant communication with the
technologist throughout the entire test by intercom. You can use the restroom
at any time during the night.
Please bring comfortable sleeping attire, as well as reading material,
a laptop computer, or anything else that may help you relax prior to bedtime.
You may also watch TV before the study begins if desired.
You will be released no later than 7:00 am the following morning. We can
also arrange an earlier release if needed.
What can I bring the night of the test?
Please bring comfortable sleeping attire and any other hygiene products
you may need to use prior to bedtime. If you have a favorite pillow or
blanket, feel free to bring them with you. We want you to feel as comfortable
as possible during your stay. You may also bring a snack, drink, or anything
else you routinely use at bedtime. Bring any medications you normally
take at bedtime or in the morning.
How should I prepare for the test?
Please avoid caffeine (such as coffee, tea, soda or chocolate) the entire
day of your study. Do not take a nap after 12:00 pm the day of your study.
Avoid alcohol unless otherwise directed by your physician. We also ask
that you shower and wash your hair prior to the study. It is very important
to not use lotions, oils, or hair products (such as gels or sprays) as
this may interfere with the sleep study.
Can I take my usual medications?
It is important to discuss the use of medications with your physician prior
to undergoing a sleep study. You should take all prescribed medications
unless otherwise instructed. Please note, we do not provide any medications
to aide in sleep.
