Preparing for Your Sleep Study
Bathe and wash your hair before coming for the sleep study.  Don’t use lotions, oils or makeup on your skin.  Men should be clean shaven unless they have a beard.  Avoid excessive amounts of caffeine the day of your study.  Bring comfortable sleepwear.  You may also bring your own pillow, reading material and any medications you need to take before bed. Inform your technologist if you need to be up at a certain time.

Sleep Disorders
There are many sleep disorders that can affect your health and quality of life. Two of the more common sleep disorders are:

Sleep Apnea - If you have sleep apnea, your throat becomes blocked during the night and you stop breathing for short periods of time. You may alternate between snoring loudly and being silent. You might gasp or snort in your sleep. If you have sleep apnea, you may:

  • Wake up tired, even after a full night’s sleep
  • Wake up with a headache
  • Feel depressed
  • Feel very sleepy or fall asleep at inappropriate times (at work or while driving)
  • Wake up choking or gasping for air
  • Be irritable and short-tempered
  • Snore
  • Have problems concentrating or remembering
  • Stop breathing for short periods during the night
  • Sleep apnea may result in health problems such as high blood pressure, heart attack and stroke.

Periodic Limb Movements - a sleep disorder where your legs and/or arms move uncontrollably during the night disrupting your sleep. 

If you suspect you may have a sleep disorder, the next step is to schedule an evaluation with your physician.  Based on the results of that evaluation, an overnight sleep study may be recommended. Sleep studies are often referred to as Nocturnal (night time) Polysomnograms (many graphs).  A qualified sleep technologist will attach several electrodes and sensors to monitor your body while you sleep. This Includes - airflow, respiratory effort, eye movements, leg movements, brain waves and oxygen levels to name a few. The procedure is painless.  You are allowed to use the restroom during the night.  Your technologist will make every effort to ensure you are comfortable during the study.  If the technologist determines that you have sleep apnea, treatment in the form of CPAP may be instituted during the night of your study.  CPAP stands for continuous positive airway pressure.  CPAP uses gentle air pressure to hold the airway open during sleep.  It is the most effective treatment for sleep apnea.
