What is a Sleep Study or Polysomnogram?
A sleep study or Polysomnogram is an overnight test which measures specific body functions during sleep to
diagnose sleep apnea along with various other sleep disorders.
This one-night nocturnal study is simple and painless and consists of a trained technologist connecting you to
our computerized monitoring equipment via various belts and electrodes. Although the information gathered
will vary depending upon your individual symptoms, in most cases the information will consist of Heart Activity,
Brain Wave Activity, Breathing, Eye and Leg Movements, Muscle Tone and Blood Oxygen Levels.
The process of attaching the equipment and electrodes will take between one and two hours. Once the
technologist has completed all the proper connections for your sleep study, he/she will go to his/her monitoring
station in another room and you will be given the opportunity to fall asleep.
There may be risks associated with not performing this study to diagnose obstructive sleep apnea and other
sleep disorders, such as an increased risk of high blood pressure, heart attacks, and other conditions, possibly
resulting in death.
What will happen next?
Your study will be analyzed and interpreted and a comprehensive report will be forwarded to your physician for
treatment recommendations. The Center for Sleep Medicine will bill your insurance for your Nocturnal
Polysomnogram and a separate bill will be submitted for the interpreting physician’s fees. Your study results
will be forwarded to your referring physician within 10 days of your study.
Other Types of Studies:
If ordered, an MSLT (Multiple Sleep Latency Test) will be performed after the nocturnal Polysomnogram. This
test consists of a series of scheduled naps that you will take throughout the day. We will provide you with
breakfast and lunch. You may watch television while you are in between naps or bring reading materials with
you. You will be released at 5:00 PM.
Continuous Positive Airway Pressure (CPAP) Titration
When you arrive at our facility for CPAP Titration, you will be fitted for an oxygen type face mask and
electrodes will be applied. A small amount of airflow pressure will be established so that it is comfortable for
you. You will then go to sleep and while you are sleeping, if you have apneic (quit breathing) events, the Technologist will
gradually increase the pressure to try and eliminate events.
What will happen next?
If it is decided that CPAP therapy is appropriate therapy for you, your physician will prescribe the machine for
you to use at home. You will not be taking any equipment home after your sleep study.
What is a CPAP machine?
CPAP stands for Continuous Positive Airway Pressure. This is a machine used to gently blow air into the
throat to keep it from collapsing. The use of this machine in patients that are positive for Obstructive Sleep
Apnea can reduce or completely eliminate the apneic events a patient can have during sleep.
CPAP may be introduced at any time during your Polysomnogram based upon your physician’s orders and/or
your meeting specific clinical criteria as set forth in specific policies.
