The Sleep Health Center at 400 North Medical Center is an AASM-accredited sleep lab in Michigan City, Indiana.

Our sleep lab has six (6) beds, two (2) of which can accommodate pediatric, ambulatory, and/or wheelchair-bound patients. Each room is private with its own shower and restroom facility, fan, and television.

For more information or to schedule a test, please call Lindsey, our sleep lab coordinator, at 219-879-0333 extension 224.

At the Sleep Health Center, we offer a multitude of tests to help your physician determine in you have a sleep disorder.

  • Polysomnogram (PSG)

    Polysomnogram (commonly known as PSG) is a sleep sutdy test that digitally records what happens to you and your body while you are sleeping. Various physiologic signals may be monitored during sleep an the test may vary based on individual patient needs. A minimum of six (6) hours of recording time is required for a valid study.

    Prior to sleep, a sleep technologist will apply surface sensors to the head and face that will allow your sleep stages to be monitored. Electrodes will be attached with a small amount or electrode paste and/or tape.

    In addition to sleep stages, the following will be monitored and recorded:

    • Heart function
    • Respiratory effort
    • Blood oxygen levels
    • Leg movements via body electrodes and chest/abdomen bands
    • Sleep position via video monitoring

    Once your test is complete, it will be scored by a registered polysomnographic technologist and then interpreted by one of our physicians. The interpretation will then be sent to your ordering physician to determine the best course of action.

  • Continuous Positive Airway Pressure (CPAP) Titration

    The goal of a Continuous Positive Airway Pressure (CPAP) Titration is to eliminate breathing problems during sleep.

    Duing a CPAP Titration, you will wear a face or nasal mask that is connected to a CPAP machine. The CPAP machine produces a high flow of air (A.K.A. Continuous Positive Airway Pressure) that blows into you mouth and/or nose to keep your airway open.

    Prior to sleep, a sleep technologist will apply surface sensors, similar to those used for the PSG test. Once your test is complete, it will be scored by a registered polysomnographic technologist and then interpreted by one of our physicians. The interpretation will be sent to your ordering physician to determine the best course of action. Your physician may order similar equipment for you to use at home.

  • Split-Night Study

    A split-night study is performed to diagnose sleep apnea. The results of this test are also used to determine effective Continuous Positive Airway Pressure (CPAP) treatment, when ordered by your physician with the approval of one of our pulmonary physicians.

    Split-night studies require specific criteria to be met during the diagnostic portion of the study before the initiation of CPAP. Prior to sleep, a sleep technologist will apply surface sensors similar to those used in the Polysomnograph (PSG) test.

  • Multiple Sleep Latency Test (MSLT)

    The Multiple Sleep Latency Test (MSLT) is used to confirm the diagnosis of patients with suspected narcolepsy. The test measures how long it takes for you to fall asleep.

    This MSLT is performed during the day, after a previous sleep study the night before. During testing, a patient takes forced “naps” every two (2) hours. Each “nap” lasts 30 minutes while movements are recorded.
