INFORMATION ABOUT YOUR SLEEP STUDY
1. WHAT IS A POLYSOMNOGRAM (SLEEP STUDY)?
A polysomnogram is a study that measures the quality of your sleep. A typical
polysomnogram includes the following measures:
• Brain waves (electrodes placed on the scalp)
• Eye movement (electrodes placed on the face, by the eyes)
• Chin muscle tone (electrodes placed on or near the chin)
• Heart rate (electrodes placed on the chest)
• Leg movements (electrodes placed on the legs)
• Breathing (breathing sensor placed near the nose and mouth)
• Breathing effort (two small elastic belts placed around chest and abdomen)
• Oxygen level (small sensor attached to the finger)
• Audio and video recording
2. WHY IS IT NECESSARY TO RECORD THE ABOVE FUNCTIONS?
During sleep, the body functions differently than while awake. Disturbed sleep, such as
irregular breathing or lack of sleep consolidation, can interfere with daytime activities, cause
daytime sleepiness, and cause serious health problems.
3. HOW CAN I SLEEP WITH ALL OF THE ELECTRODES?
Most people sleep reasonably well. We are looking to obtain a sample of your sleep pattern.
The body sensors are applied so that you can move during sleep and change positions during
the night. The sleep rooms are set up as comfortable bedrooms, and our staff makes the
environment as restful as possible.
4. WILL THE SENSORS HURT?
No. This is a painless and non-invasive (no needles) testing procedure. Paste is applied to
your skin and scalp to keep the electrodes in place, but it is easily removed with soap and
warm water.
5. WHAT IS A MULTIPLE SLEEP LATENCY TEST (MSLT)?
Some people also participate in daytime testing. This test consists of a series of 20-minute
naps. Sensors and electrodes are used to record information similar to the polysomnogram
test. 20-minute naps are taken every two hours throughout the day. Please bring something
to read or work on during the day to help keep you occupied in between naps. A DVD player
is available. The MSLT test is usually completed by 6:00 p.m.
6. IS THIS STUDY COVERED BY INSURANCE?
Sleep studies are covered under most medical insurance plans, although deductibles and
percentages of coverage vary. Details regarding coverage should be directed to your
insurance company. We will verify insurance benefits and coverage prior to your sleep
study. Feel free to call The Hammond Clinic Sleep Center (219)836-7535 or toll free (800) 840-5800 and speak with the Sleep Coordinator, who is available to answer any remaining questions or concerns you may have.

5. HOW IS THIS CPAP TITRATION SLEEP STUDY DIFFERENT FROM MY FIRST
SLEEP STUDY?
The only difference between the CPAP titration sleep study and the first (diagnostic) sleep
study is that, in addition to all of the wires that were used in the first study, the technician
will fit you with a CPAP mask, and you will sleep with the CPAP machine on. Our goal
during this study is to determine an effective pressure with which to treat your sleep apnea.

1. HOW IS THIS ORAL APPLIANCE SLEEP STUDY DIFFERENT FROM A
REGULAR POLYSOMNOGRAM (SLEEP STUDY)?
The only difference between the ORAL APPLIANCE sleep study and a polysomnogram
(sleep study) is that, in addition to all of the wires that are used; the technician will ask you to
sleep with your oral appliance in place. Our goal during this study is either to document the
effectiveness of your fixed position oral appliance or with adjustable appliances, to determine
the most effective position with which to treat your sleep apnea.

The Multiple Sleep Latency Test (MSLT) often follows a nighttime sleep study. It will
start approximately 2 hours after you wake. This time varies and depends on information
collected from your nighttime study.
WHAT IS AN MSLT?
An MSLT monitors sleep patterns to determine the degree of daytime sleepiness. The
test consists of a series of five naps starting approximately 2 hours after you wake in the
morning and continuing every two hours thereafter. Sensors and electrodes are used to
record information similar to the nighttime sleep study. These sensors measure:
- Brain waves (electrodes placed on the scalp).
- Eye movements (electrodes placed on the face by the eyes).
- Chin Muscle tone (electrodes placed on or near the chin).
- Heart rate (electrodes placed on the chest).
INSTRUCTIONS FOR THE MSLT:
- Do not come for your sleep studies sleep deprived. It is recommended that you
get 8 hours sleep every night for 2 weeks prior to your sleep study and make sure
to get a good night’s sleep the night before.
- Follow the sleep specialist’s directions regarding medications - Stop taking any
medicines as directed and for the length of time as directed.
- You will typically be required to have a urine test for drugs the day before or the
day after you have the MSLT.
- Please do not make plans for the evening of your MSLT since the time varies as
to when your study will be complete. You may be at the sleep center until as late
as 8 pm, but most likely will be done by 5 to 6 pm.
- You may bring something to read or work on during the day to help keep you
occupied in between naps. A television and DVD player are available.
- Breakfast and lunch will be provided.
