What to Expect During Your Sleep Study

Having a Sleep Study evaluation at the Los Angeles Sleep Study Institute is easy and painless. Small sensors will be placed on your head, face, neck, chest, and legs. You will meet with your technician to discuss the procedure, answer any of your questions and review your enclosed sleep questionnaire. Please feel free to bring someone to accompany you during your hook-up in preparation for your sleep study. Your guest will be required to leave once the technician begins the study. You will sleep in your own private bedroom. Pillows are provided but feel free to bring your own.

Your physician, who ordered this test, still has control over your treatment. Sleep Study Institute is just providing the test. Any questions you may have should be addressed to your physician. These tests will record detailed information about how your body acts while you sleep. This test is most often performed overnight, but may, under certain situations, be performed during the daytime. A technician will attach sensors to your body for the study. The sensors will keep track of these body functions:

  • Brain Waves
  • Heart Rate and Rhythm
  • Breathing Rate
  • Blood Oxygen Level
  • Eye Movements
  • Snoring
  • Leg Movements
  • Jaw or Chin Movements

If treatment with nasal CPAP and/or oxygen is ordered by your physician, then your follow-up will be done with your physician and the Nationwide Medical Group Company will contact you. Your physician already knows that if he has any questions about your treatment he can contact the physician who read the sleep study.

Electrodes will be taped or glued to your head, face, chin and behind your ears to measure sleep stages or indicators of sleep. None of these electrodes will be inserted into the skin itself. Electrodes will be taped to your chest and side to measure your heart activity during sleep. A sensor will be taped to your upper lip to measure nasal/oral airflow and bands will he placed around your chest and abdomen to measure effort. A monitor will be placed on your finger which will shine a light through the finger to indicate how much oxygen is carried in the blood. All of these electrodes combined indicate how well you sleep, how well you breathe, if you have enough oxygen during the night and/or other problems are waking you up during the night. Although we try to use electrodes and tape that people are not usually allegoric to, some people may still develop red areas from where the tape and electrodes were placed. These red areas will eventually fade away.

Nasal CPAP is a machine that is attached to a mask, which is placed on your nose. Air is sent through the nose to act like an air-splint on the back of your throat. This form of therapy is used primarily to treat you for obstructive sleep apnea or hypopnea. Both of these conditions, and more, will be explained to your by the sleep study technician. If ordered by a physician, oxygen may be started and adjusted to maintain proper oxygen levels at night. If you are already on oxygen, it may be adjusted to obtain optimal oxygen levels.

Keep in mind that only a physician can diagnose and decide treatment for a patient’s condition. Comments made by the technician are to help you understand why certain things are being done, but may not necessarily be your final mode of treatment. Information gathered by the technician is passed on to the physician to help in his interpretation. Please wait for the formal interpretation of your sleep study.

The sleep study will be performed in an ASC/Hospital/Clinic setting. That hospital/clinic’s normal emergency procedures will be followed. If an emergency occurs during the night of your test, the sleep technologist is trained in CPR.

Although a Sleep Study session usually requires only 6.5 hours to complete, at Los Angeles Sleep Study Institute we recommend a sleep study lasting at least 7 to 8 hours. The longer your Sleep Study lasts, the more information your Sleep Study Doctor will be able to interpret and evaluate the sleep study results. Sleep study results are typically available for discussion 5-7 days after your Sleep Study Session.

How to Prepare for a Sleep Study

We aim to make your experience at the Los Angeles Sleep Study Institute as comfortable and pleasant as possible. With proper preparation, your sleep study can be incredibly effective at finding your disorder, and a treatment for your sleep disorder can be found more efficiently.

Preparation for your sleep study should include:

  • Comfortable clothing to sleep in, preferably two piece pajamas.
  • If it allows a better night's sleep, you may bring your own pillow.
  • Avoid consuming all caffeinated or alcoholic beverages during the day of the sleep study.
  • Try not to nap the day of the sleep study.
  • Make sure to eat your normal dinner before you arrive at our facilities.
  • If needed, you may bring a light snack.
  • Shower and wash your hair the evening before the sleep study. Please do not use any oil, lotions or hair products. Such products can make it harder to attach the various tracking devices to your body.
  • Any medications you take before bedtime. Unless your sleep specialist tells you otherwise, take your prescribed medicine accordingly.
