Welcome to Heart Healthy Sleep Center!

You have been referred to our center for an overnight sleep study.

This test will allow us to monitor your sleep in order to determine which, if any, sleep disorder you may have.  This is a completely painless, non-invasive diagnostic test that uses small cup electrodes to monitor your brain waves, the levels of sleep that you attain, your heart rhythm, your eye movements, leg movements, and respirations.  Our goal is to provide a quiet and comfortable out-patient like atmosphere that is as much like a regular night’s sleep as possible.  Please feel free to bring any items that you may need to ensure a restful night. 
We look forward to having the opportunity to help you get a better night’s sleep.

Instructions for the Day of Your Study

  1. Avoid taking naps on the day of your study.
  2. Avoid caffeine after 10:00AM (includes soda, tea, chocolate and coffee) the day of your study.
  3. Please refrain from consuming any alcohol the day of your study.
  4. Hair and skin should be clean and oil free.  Hair should be loose.
  5. Take your usual medications unless otherwise instructed by your physician.
  6. Bring comfortable sleeping attire.  Wear loose fitting two-piece pajama sets or shorts and a loose fitting t-shirt.  Do not wear anything tight around the ankles.  Please keep in mind that you will not be allowed to sleep without clothing, nor will you be allowed to sleep solely in your underwear.
  7. You may bring your own pillow if you desire.
  8. If this is your first time at our center, please bring your completed Sleep History Questionnaire.



A specially trained technician will conduct the evaluation.  After you are dressed for sleep, the technician will apply approximately 15 small, lightweight electrodes – with a thick paste – to your scalp and skin.  You may feel a slight tingling sensation where the skin is cleaned, but that is all.  Once you are in bed, the technician will apply an oxygen sensor to your finger and straps around your chest and stomach to help measure your breathing and how your sleep is being disrupted.  The wires attached to the monitors are plugged into a box and then into a cable making it easy to disconnect, should you need to get out of the bed during the night to use the bathroom.  All that is required is to disconnect the cable.  The technician will be in an adjacent room monitoring your sleep.  You will be observed by both camera and intercom should you need anything.

An overnight sleep study usually ends around 5:00AM to 5:30 AM the following morning.  If a “nap study” or Multiple Sleep Latency Test is requested, it follows the overnight study and ends around 4:30 PM.

A tremendous volume of sleep information is collected on computer. A lab technician scores all of the data.  Then, the sleep study, your sleep history, physical examination, observation notes from the technicians, and any other testing you may have had performed will be forwarded to the Sleep Specialist.  Careful interpretation of all results is then undertaken, and this leads to a diagnosis of the sleep problem, as well as recommendations for treatment.  The final report should be completed in ten to fourteen days.  You will probably have a follow-up visit with your referring physician and/or the Sleep Specialist to discuss the results and appropriate treatment options.  If you have any questions, do not hesitate to ask.  The sleep lab personnel are ready to help you understand and make you comfortable during your stay in the sleep lab.
