Sleep Disorders Center Tests & Procedures

    The Sleep Disorders Center is committed to making a thorough assessment of your child's sleep issues so that we can fully understand their condition and create a treatment plan.

    The Sleep Disorders Center offers a variety of testing procedures to help diagnose various sleep disorders.

    Actigraphy
    EKG of the Heart
    Lab Work
    Memory Monitor
    MRI Scan
    Multiple Sleep Latency Testing
    Polysomnography
    Portable Studies
    Radiology

    Actigraphy

    This is a study done with a small biomedical instrument, typically worn on the wrist, that measures and records body movement. It can be used to define sleep-wake cycles clearly and objectively based on documenting the body movement during wake and lack of movement during sleep periods.

    EKG of the Heart

    This may be ordered to assess any potential damage to the heart from untreated or undertreated breathing obstruction.

    Lab Work

    Blood work may be ordered to rule out endocrine and metabolic disorders.

    Memory Monitor

    Painless memory monitors may be worn for a period of time so that staff can analyze specific brain functions recorded by the monitors.

    MRI Scan

    Scans may be ordered to rule out brain stem abnormalities.

    Multiple Sleep Latency Testing

    Objective measurement of the tendency to fall asleep is performed on patients with disorders of excessive sleepiness during multiple opportunities to nap. This test is particularly valuable in diagnosing narcolepsy.

    Polysomnography

    Overnight sleep studies are done in a soundproof bedroom in the sleep lab. A technician monitors the patient throughout the night and video equipment is utilized to record the entire procedure. A computerized sleep system records EEG, ECG, respiratory effort, muscle tone, tidal volume, oxygen saturation and entidal CO2.

    Portable Studies

    These studies can be done on the nursing unit or in the lab. They are often done with a pH probe and are performed at night when the patient is asleep. An apnea monitor is interfaced with a multi-channel recorder to monitor patient’s respiratory effort, airflow, heart rate and oxygen saturation.

    Radiology

    X-rays most often are ordered to assess the soft tissue of the neck to see if there is obvious obstruction.
