All sleep studies performed at the Abbott Northwestern Hospital Sleep Center are conducted in a comfortable, secure, private bedroom.

Tests commonly done in our sleep laboratory are:

  • Polysonogram (PSG) evaluates the quality of nighttime sleep, monitors sleep patterns, breathing, heart activity, brainwaves and body movements. It is performed on patients while they stay overnight at our facility.
  • Multiple sleep latency test (MSLT) is performed on the day following a polysonogram to evaluate the degree of sleepiness and the patterns of sleep during daytime naps.
  • Maintenance of wakefulness test (MWT) monitors a patient's ability to stay awake over time.
Seize the day. Start the night before. Wake up to the benefits of a better night's sleep.
