Our staff is committed to making your visit to Torrance Memorial Sleep
Disorders Center as comfortable and convenient as possible. We welcome
the opportunity to discuss your special needs and concerns, and appreciate
your suggestions and comments.
What about payment and insurance?
Torrance Memorial Sleep Disorders Center will bill your insurance if we
receive complete and accurate insurance information. Because insurance
plans and benefits vary greatly, specific questions about your policy
and coverage -including co-pays and deductibles - should be directed to
your insurance carrier or employer.
What is a sleep study?
Your physician or our sleep specialists may recommend that you have an
overnight Sleep Study to determine if you have a sleep disorder. A Sleep
Study, also called a Polysomnogram, is a painless, non-invasive test that
records your physical state during various stages of sleep. It provides
data that are essential in evaluating sleep and sleep-related complaints
and problems, such as identifying sleep stages, body position, blood oxygen
levels, respiratory events, muscle tone, heart rate, eye movement, brain
waves, amount of snoring, and general sleep behavior.
Sleep studies are performed in a Sleep Lab that is specially equipped with
computerized monitoring equipment. Studies are performed at our at our
Sleep Disorders Center.
What happens during a sleep study?
Do you want to know what to expect? Here is a brief preview, with some
suggestions on how to prepare for your sleep study. Please do not hesitate
to call our Sleep Center at 310-517-4738 prior to your exam if you have
Most sleep studies take place at night. After we receive an order from
your healthcare provider, our scheduling staff will call you to schedule
a convenient date for you. We conduct overnight sleep studies seven days
a week. We will also request some medical history. You will be asked some
questions about your sleep habits, and you will be given instructions
You will be asked to arrive for your overnight Sleep study at approximately
8:30 pm. After you arrive, you will be shown to your own private room
where you will watch a video that will address what you should expect
during your study. Then, you will be asked to change into the nightclothes
you have brought with you.
After changing, your Polysomnographic Technologist, who has advanced training
in performing Sleep Studies, will connect you to a number of electrodes
that will record your brain waves and muscle movements throughout the
night. A microphone will record snoring, and two belt-like straps around
the chest and lower abdomen will monitor muscle movement during breathing.
Despite all of the equipment, most people say it doesn't disrupt their
sleep. After your technologist is certain that the electrodes are recording
properly, the lights will be turned off and you can go to sleep.
You will be able to talk to your technologist who will constantly monitor
your exam from an adjoining room. The technologist will also help you
get up during the night if you need to use the restroom.
If you are being tested for Sleep Apnea, you may undergo a "split-night"
test, in which half the night will be used to diagnose your sleep problem,
and the other half will be used to determine the best way to treat the
problem. Or, you may be asked to return for another Sleep Study in order
to determine the best way to treat your Sleep Apnea.
You will be awakened in the morning, usually around 5:30 or 6:00 am. The
electrodes will be removed, and you may shower and dress. Since the electrodes
are applied with water-soluble glue or tape, removal is not painful.
You will be asked to complete a questionnaire concerning your sleep the
previous night, and then you can go home.
If you take a sleep medication on the evening of the study, you should
make arrangements for a ride home the following morning after your sleep study.
How will I receive my results?
Because trained and experienced sleep specialists interpret all exams,
you will not receive your study results from the technologist who performed
your test. Our doctors will report the results to the physician who ordered
your sleep study in approximately seven to ten days. Your physician will
explain the results to you and talk with you about follow-up treatment,
If your sleep study was ordered by one of our sleep specialists, you will
be informed of the results and any follow-up treatment that may be required
at the time of your next office visit.
If you would like a copy your exam after you have talked with your physician,
call us at 310-517-4738.
What should I bring to the sleep study?
- Your ID and insurance information
- Pajamas or any comfortable sleep wear, preferably with a button-down front.
- Your favorite pillow and blankets. We provide pillows and blankets, but
yours may help you sleep better.
- Toiletries such as toothbrush, toothpaste, hairbrush or comb
- Clothes for the following day
- Any needed medications
- A book or other reading material
What do I do the day of the sleep study?
Wash and dry your hair on the day of your sleep study. Do not use any hair products, such as gels, hairsprays or heavy conditioners,
because these may prevent the electrodes from sticking to your scalp.
Remove nail polish and/or artificial nails from at least two fingers. The oximeter that is placed on your finger to monitor blood oxygen levels
reads this information through the nail.
Do not wear make up. Some electrodes are on the face, so that area must be clean in order
to get a good connection.
Generally, you will be asked to continue to take your regular medications. You will be notified in advance if you should alter your medications
on the day of the exam.
- Do not drink any caffeinated beverages after noon on the day of your study.
What if my doctor prescribes a CPAP?
If you are found to have Sleep Apnea, CPAP, or Continuous Positive Airway
Pressure, may be prescribed by your physician. This common and effective
treatment provides pressure to your airway through a machine that blows
air. The airflow from the CPAP machine is delivered through a mask that
fits on your face and covers the nose, or the nose and mouth. This air
acts as a splint to keep your airway open during sleep, allowing breathing
to become more regular. Snoring stops and restful sleep is restored. Risk
factors associated with untreated sleep apnea are greatly reduced when
CPAP is used as prescribed by the doctor.
