Sleep Disorder Testing
How do I get tested for things like sleep apnea and upper airway resistance?
Those concerned that they may have some sleep disorder should get tested by medical professionals like Dr. Thomas. There are a variety of tests that can be performed to get an accurate diagnosis so and effective treatment plan can be implemented.
What tests to I need?
An important first step of sleep testing at the Intermountain Neurology & Sleep Center is to be interviewed by our specialists. We need to understand the extent of your sleep problems, the exact symptoms you’re feeling, your medical history and the duration of the problem.
With that information, further studies can be conducted, each based on your specific condition.
Testing Breathing: There are various tests that measure your breathing while sleeping. Sometimes this involves sleeping overnight at our center. Polysomnograms measure respiratory effort, among other things. Continuous Positive Airway Pressure (CPAP) Titration is important for seeing how much air pressure is needed to treat obstructive sleep apnea.
Testing Oxygen Levels: Related to breathing, some sleep tests measure oxygen saturation levels. Blood oxygen levels shouldn’t be below a certain level. These measurements can determine the severity of obstructive sleep apnea.
Testing Brain Activity: An electroencephalogram (EEG) measures brain activity to detect abnormalities. While this test is important for diagnosing many neurologic issues, it can also help diagnose narcolepsy.
Daytime Sleepiness: Some tests are performed during the daytime, to properly diagnose problems like narcolepsy and excessive daytime sleepiness. One test, called the Multiple Sleep Latency Test (MSLT), measures how fast a person falls asleep.
