Sleep Studies Conducted

The Center conducts five types of tests using sophisticated diagnostic equipment to monitor brain, heart, respiratory, and muscle activity during sleep.

  • Polysomnography (PSG): Monitors a person’s sleep in order to identify sleep disorders and sleep-related breathing disorders.
  • PSG with Continuous Positive Airway Pressure (CPAP) Titration: For sleep-related breathing disorders. When a home-based CPAP machine is recommended, the patient will first receive this test at the Center to determine the clinically appropriate and most comfortable settings for the CPAP machine.
  • Split Night Study: During a PSG, the technical staff may identify conditions that warrant terminating the PSG and beginning a CPAP titration study that same night.
  • Multiple Sleep Latency Test (MSLT): Conducted during the daytime, the patient takes a series of naps while monitored by sleep testing equipment. This test measures a person’s ability to fully awaken from sleep and is used for people with excessive daytime sleepiness. It is frequently done with a PSG.
  • Measurement of Wakefulness Test (MWT): Measures a person’s ability to stay awake during conditions of limited sensory stimulation. This test is useful for those who must demonstrate the ability to stay awake to perform job duties safely (i.e. pilots, truck drivers, and heavy machine operators).
