What is an in-lab sleep study?Man getting sleep study with device and cords.

An in-lab sleep study, also called a polysomnogram, is a non-invasive, observation-based evaluation that takes place overnight in our private sleep lab. While home-based testing is also available, an in-lab sleep study provides the most comprehensive evaluation of your sleep. Using painless sensors, a sleep study records your brain waves, heartbeats, and breathing. It also charts your eye movements, limb movements, and oxygen in your blood. The data gathered will help your provider to make a diagnosis.


Why an in-lab sleep study?

In-lab sleep studies can help determine if the symptoms you are experiencing are related to a sleep disorder. Sleep disorders usually result in poor quality sleep and chronic sleep deprivation. Left untreated, patients with sleep disorders are more likely to develop or suffer from Type 2 diabetes, high blood pressure, obesity, a compromised immune system, depression, stroke, and memory loss. By participating in a sleep study, you can get the correct diagnosis and an accurate treatment plan to help you manage or avoid chronic conditions and live a healthy life.

What can an in-lab sleep study help diagnose?

A sleep study can help your provider diagnose a sleep disorder. Sleep disorders include, but are not limited to, conditions such as obstructive sleep apnea, narcolepsy, insomnia, sleep paralysis, central sleep apnea, and restless legs syndrome.  If you suspect that you have a sleep disorder, talk with your provider about your symptoms. If your provider determines that your symptoms may be linked to a sleep disorder, they may refer you for an in-lab sleep study.

What to expect during an in-lab sleep study

During a sleep study, a Registered Sleep Technologist will apply a series of sensors to your head, face, chest, and legs. These sensors monitor your breathing patterns, oxygen levels, sleep stages, and movements, which helps to determine if your sleep is disturbed. Each sensor plays an important part in diagnosing any sleep disorder you may have.
