Sleep Study

The following is information for those individuals whose history and physical evaluation indicate that a sleep study should be performed.  This involves an overnight stay in the Sleep Lab where monitoring will be performed by our staff monitoring brain waves, breathing patterns, body movements and heart rhythms.

Services Offered

The following services are offered at the Sleep Medicine Center:
 

    CPAP MasksPSG (Polysomnogram) - the continous and simultaneous recording of physiological variables during sleep (EEG, EOG, EMG - the three basic stage scoring parameters), EKG, respiratory airflow, respiratory movements, limb movements, and other electrophysiological variables.
        
    CPAP (Continous Positive Airway Pressure) - Breathing system to help you breath during sleeptime by providing positive pressure air via a mask.  The positive pressure air keeps the airway open during sleep to prevent airway collapse.
        
    PSG/CPAP
        
    MSLT (Multiple Sleep Latency Test) - A series of measurements whereby subjects are allowed a fixed number of opportunities to fall asleep during their customary wake period (usually day time).  Excessive sleepiness is characterized by short latencies (the time measured between going to sleep and actual onset of sleep).  Long latencies are helpful in distinguishing physical tiredness or fatigue from true sleepiness.  
        
    Humidifier - moistened air

What is a Sleep Test

Patient in Bed A polysomnogram is a test which measures bodily functions during sleep.  Each test will vary depending on the individual case.  Some of the measurements taken may include:

  • Brain waves  (skin surface electrodes on the head)
  • Heart rhythms  (skin surface electrodes on the chest)
  • Eye movement  (skin surface electrodes above and below the eyes)
  • Leg movements  (skin surface electrodes on the lower legs)
  • Breathing effort and movement  (small elastic guages placed around the chest and/or stomach)
  • Blood oxygen levels  (small sensor attached to the ear or finger, and not taken from actual blood samples)


WHY RECORD ALL THESE THINGS?
During sleep, the body functions differently than while awake.  Disrupted sleep can disturb daytime activities and can involve risk to basic health.

HOW CAN I SLEEP WITH ALL THESE THINGS ON ME?
Surprisingly, most people sleep very well.  The body sensors are applied so that you can turn and move in your sleep.  Generally, you will not be aware that you are wearing devices after they have been on for a short time.  Our staff tries to make the environment as comfortable and similar to your home surroundings as possible.

Sleeping Room WILL THE SENSOR DEVICES HURT?
No.  Sometimes in rubbing the skin there are mild and temporary skin irritations.  You may also feel a sensation of warmth where the oxygen-measuring device contacts your skin.  However, these do not generally cause any significant discomfort.

WILL I BE GIVEN A DRUG TO HELP ME SLEEP?
No.  In fact, we prefer, to the extent medically possible, that you be off sleeping medications for at least eight (8) days before coming in for the test.  Some drugs will need to be stopped even longer prior to the test.  It is also important not to consume any alcohol or caffeinated beverages on the day of the test.  If however, you have difficulty falling asleep, and you meet our criteria, then you may be given a mild sleeping medication that will otherwise not interfere with the test.

IMPORTANT NOTE
Please DO NOT stop any of your medications without first consulting your regular physician. The only medications that should be discontinued are those used to keep you alert or medications used as a sleeping aid.

WHAT IS A MULTIPLE SLEEP LATENCY TEST?
Some patients also participate in daytime testing.  This test consists of a series of 20 minute naps.  The same kind of information is measured as in a polysomnogram.  These naps are given every two (2) hours throughout the day.  We ask those patients participating in this test to try and go to sleep even though they may feel they can't and that they remain awake between nap periods.

After the Test

WHAT HAPPENS TO THE TEST?
A general overview occurs during the night while you sleep, with the sleep technician following guidelines directed by the physican for initiation of therapy if indicated.  This is then analyzed by hand later, and, after review by the sleep physician, an official complete report follows within 10 to 14 days.  It is then kept on file in our records at the Sleep Lab for future reference.

WHAT HAPPENS THEN?
An appointment will be made with the sleep physician to go over the detailed results of your test and evaluation of any therapy.
