    Testing

    After your consultation, you may be asked to come in for diagnostic and/or therapeutic tests. Diagnostic tests are done at the sleep clinic and are designed to help determine whether or not you have a sleep disorder. Therapeutic studies are designed to provide relief for a diagnosed sleep disorder. Here are some of the tests we may perform:

    • Polysomnogram, a diagnostic sleep study performed in the clinic. It is used to evaluate sleep stages and diagnose sleep disorders such as insomnia, snoring and sleep apnea.
    • Continuous Positive Airway Pressure (CPAP) Titration, a therapeutic sleep study performed at the clinic. Your sleep is monitored while you are on CPAP therapy to determine the effectiveness of your sleep disorder treatment.
    • Split-night polysomnogram/CPAP combines the two previously described sleep studies. The diagnostic part is done for three hours, and then you are put on CPAP for the remainder of the study.
    • Tests for sleepiness:
      • Mean Sleep Latency Test (MSLT) done as a series of naps and is used to assess daytime sleepiness.
      • Maintenance of Wakefulness Tests (MWT), used to measure the level of alertness you have during the day. It shows whether or not you are able to stay awake for a defined period of time.
    • Testing at home

    A polysomnogram measures:

    • Brain Waves (EEG)
    • Heart Rate (EKG)
    • Eye Movement (EOG)
    • Muscle Movements (EMG)
    • Limb Movements (EMG)
    • Breathing (Nasal/Oral)
    • Breathing (Respiratory Effort)
    • Blood Oxygen Levels (Sp02)
    • Esophageal Pressure (PES)
