  • What is a Sleep Study? A sleep study is also known as polysomnography. Polysomnography is a testing procedure that measures a variety of physical activity and brain functions during a sleep session. During these sleeping sessions, the Indiana Sleep Center's highly trained technicians will monitor a variety of body functions. Each individual test is personalized and may include each and any of the following measurements.

  • Brain Wave Activity
  • Heart Rhythms
  • Eye Control
  • Tone in Muscles
  • Grind or Clenching of Teeth and Jaws
  • Snoring
  • Leg Movements
  • Airflow through Nasal or Mouth
  • Effort in Breathing
  • Oxygen Levels in the Blood

    Each of these signals are measured through non-invasive devices such as electrodes and sensors placed on various parts of the body. There isn't any pain involved in any of these tests. The testing devices are attached to the skin of the patient with paste or tape. In rare occurrences, a mild skin irritation may occur from the adhesives. Skin sensitivities to paste, tape or latex materials must be disclosed prior to overnight monitoring.

    • Why is Monitoring Important? Sleep disruptions can affect a patient's daily life. Disturbances in sleep patterns can be a sign of specific medical conditions that only occur during sleeping sessions. Our board certified trained staff monitor a variety of brain functions and activities during sleep sessions to focus on a patient's sleeping patterns to determine if there is a larger medical condition at stake. By doing this, a professional diagnosis is made and can help a patient lead a comfortable and refreshed life.

    • Making a Sleep Study Comfortable. The Indiana Sleep Center takes pride in the state of the art facilities that are equipped with all of the comforts of home. If staying overnight in a foreign place makes the patient uneasy, there are a few things a person can do to help make their stay more pleasant and relaxed.
      • Bring comfortable nightclothes to wear to bed
      • A book to read or something to work on while awake
      • Personal bath items
      • List of current medications
      • Favorite pillows or sleeping blankets
      • A completed Indiana Sleep Center Questionnaire and Sleep log

    • Sleep Apnea effects more than 18 million American adults. OSA occurs in all age groups and both sexes, but there are a number of factors that increase risk, including having a small upper airway (or large tongue, tonsils or uvula), being overweight, having a recessed chin, small jaw or a large overbite, a large neck size (17 inches or greater in a man, or 16 inches or greater in a woman), smoking and alcohol use, being age 40 or older, and ethnicity (African-Americans, Pacific-Islanders and Hispanics). Also, OSA seems to run in some families, suggesting a possible genetic basis.

    • Restless Leg Syndrome (RLS) affects approximately 10% of adults in the U.S. Researchers believe that RLS is commonly unrecognized or misdiagnosed as insomnia or other neurological, muscular or orthopedic condition. RLS may also be confused with depression. According to the Restless Legs Syndrome Foundation, approximately 40% of people with RLS complain of symptoms that would indicate depression if assessed without knowledge or consideration of a sleep disorder.

    • Insomnia is the most common sleep complaint among Americans. It can be either acute, lasting one to several nights, or chronic, even lasting months to years. When insomnia persists for longer than a month, it is considered chronic. According to the National Center for Sleep Disorders Research at the National Institutes of Health, about 30-40% of adults say they have some symptoms of insomnia within a given year, and about 10-15 percent of adults say they have chronic insomnia.

    • Snoring is noisy breathing during sleep. It is a common problem among all ages and both genders, and it affects approximately 90 million American adults - 37 million on a regular basis.
