Our full service sleep center provides a comprehensive evaluation and treatment of all sleep disorders. Each patient receives a customized treatment plan designed to meet their specific sleep needs.

Preparing for your sleep study

To get the most accurate results out of your sleep study, we ask that you go about your normal routine as much as possible. However, there are a few tips you can follow to make the study go more smoothly:

  • Try to follow your regular routine.
  • Avoid napping.
  • Eliminate use of caffeine and other stimulants after lunch.
  • Remove nail polish. You will be wearing a pulse oximeter on one index finger.
  • Avoid using hair products that can interfere with sleep recording.
  • Avoid using oils and lotions.

You may be advised to limit the use of tobacco products prior to your sleep study. If you are on regular medication, please notify the sleep medicine physician. Some medicines can affect the sleep study results, so the doctor may recommend for you to temporarily discontinue using medication.

What to bring

  • All regular prescribed medications.
  • Insurance card and identification.
  • Reading material.
  • Your current CPAP/Bi-level medicine mask (if using).
  • Toiletries such as toothbrush, toothpaste, comb, brush, etc.
  • Favorite pillow or blanket if desired.
  • Comfortable pajamas or clothes to sleep in. Although your comfort is very important, we prefer you wear two-piece pajamas. Nightgowns or one piece pajamas are not generally considered acceptable and nudity is not permitted.
  • A change of clothes for the next day.

Upon arriving at Crescent Medical Center Lancaster

We ask that you enter through the Emergency Room where our registration staff will get you entered into the system. Once you are registered, the sleep technician will come greet you and show you to your room. It is important that you arrive at or before your schedule time.

What to expect during a sleep study

Once you have become settled in your room, you will be asked to complete some paperwork and change into your bedclothes. The sleep technologist will apply sensors and electrodes to your scalp, face, chest, limbs, and finger. This process will take about an hour. Please be patients and take directions from your technologist. Once the sensors and equipment are in place, you will be able to walk around and use the restroom without assistance.

While you sleep the sensors record your brain activity, eye movements, heart rate, blood pressure, and blood oxygen levels. Elastic belts are placed around your chest and belly. These are used to measure chest movements, as well as strength and duration of inhalation and exhalation.

Your technologist will administrate the study from another room, where there is a computer recording the data form your sensors. Sleeping with equipment might be a little uncomfortable, but your technologist will do everything they can to ensure you are as comfortable as possible.

Our trained staff doesn't just care for injuries, they care about you.
