WHAT IS A SLEEP STUDY (POLYSOMNOGRAM)?

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

A Polysomnogram is a diagnostic procedure which measures certain body functions during sleep.  Electrodes are placed on several areas of your body including your head, face, legs, chest, waist and finger.  In order to locate the electrodes on your scalp, we will measure your head, mark your scalp with an erasable pencil and secure the electrodes with a washable paste (please contact us immediately if you have a permanent hairpiece or weave). The application of these sensors is painless and can take 45 minutes to an hour to apply.  Their purpose is to record your oxygen level, brain waves, airflow, snoring, leg movements and heart rhythms. The following parameters will be monitored during your study:

 

  • EEG/Brain Waves (Electrodes must be placed on scalp, a hairpiece or weave may interfere)

  • EKG/Heart Rate (Electrodes placed on the chest)

  • EOG/Eye Movements (Electrodes placed above and below eyes)

  • EMG/Muscle Tension (Electrodes placed on the chin)

  • EMG/Muscle Tension (Electrode placed on both legs)

  • Airflow/Breathing (Sensors attached near nose and mouth)

  • Respiratory Effort (Elastic belts placed around chest and stomach)

  • Oximetry/Blood Oxygen Levels (Small sensor attached to finger)

 

WHY RECORD ALL THESE THINGS?

 

During sleep, the body functions differently than while awake.  Disrupted sleep, like having sleep apnea, can disturb your daytime activities and create further medical problems. Overall, good restful sleep is required to promote good basic health.

 

HOW CAN I SLEEP WITH ALL THESE THINGS ON ME?

 

We hear this all the time, surprisingly, most people will sleep the way they usually do at home.  The body sensors are applied so that you may turn and move in your sleep as you normally would.  This is a non-invasive procedure meaning that no needles will be involved and the procedure is painless.  Our staff will try to make your sleeping environment as comfortable as possible.  Remember, this is not a performance test, only a sample of how you sleep.

 

The Sleep Center provides a light snack and flat screen cable televisions to make your stay as comfortable as possible. You may go to sleep at your normal bedtime within the constraints of the lab protocols. Keep in mind, the earlier you go to bed, the more time we have to evaluate your sleep. Some patients will use CPAP during the night. During the night, a technologist will be available to assist you as needed. Typically, we begin waking patients at 5:30 am, unless a later or earlier wake up time is desirable. Please keep in mind that the equipment takes approximately 20 minutes to remove. There are showers and towels in all of our bathrooms to freshen up before leaving the lab by 6:15. Coffee and a light breakfast are also provided by The Sleep Center.

What to do the night of your Sleep Study:

 

  • Avoid caffeine or other stimulants after 4 pm on the day of your study.

  • Eat a light dinner.

  • Please arrive with your hair and skin clean and dry. Do not use lotions, oils, gels, or sprays on your hair or skin.

  • Unless wearing a full beard, men must be clean shaven (no stubble). 

  • Do not take a sleep aid prior to your arrival. Please ask your attending technician when you should take it. 

  • Upon arrival, your attending technician will be working diligently to get you prepared for bed. Ideally, the sooner you can try to go to sleep, the better. However, if you must watch some TV or work on your laptop, we ask that it be kept to a minimum. Again, our main concern is to get enough sleep time to ensure a valid sleep study for you and your physician. Thank you for your understanding.

  • For a complete study, it is best to have six to seven hours in bed. Your sleep study will end between 5:00 and 6:00 A.M. You will be discharged from the lab no later than 6:15 A.M. (unless prior arrangements are made).

 

Who can stay with me?

 

Guests are not permitted to stay overnight, though arrangements for caregivers can be made when necessary. For children under 18 years of age, disabled, or otherwise non-independent patients, we require and allow only one parent or caregiver to stay overnight. A recliner is available in the room for the caregiver to sleep. Sharing the bed will interfere with the sleep study.

 

What about food?

 

Please eat before you arrive. The Sleep Center will provide snacks and drinks for refreshments. Coffee and a light breakfast are available in the morning for overnight study guests. Patients who are undergoing MSLT or MWT studies can have food delivered to The Sleep Center by a number of different restaurants in the area that provide delivery.
