Sleep Study/Apnea Test

Testing for sleep disorders may begin with a special screening device used at home. As needed, a sleep study (polysomnogram) may be suggested. This test, done in the Sleep Center, is often carried out at night so that normal sleep patterns can be monitored. During the exam, your brain, heart and muscle activity and eye movement are recorded, and your heart rate, blood oxygen level and breathing are monitored.

In addition to detecting sleep apnea, this test may help diagnose or rule out the reasons for:

  • Circadian rhythm sleep disorders
  • Insomnia
  • Narcolepsy
  • Nocturnal behaviors
  • Restless legs syndrome/periodic limb movement disorder
  • Sleep disordered breathing
