Types of Sleep Studies

Find out which sleep studies we perform and why they are performed.

Battling insomnia? Dealing with loud, chronic snoring? Worried you might have sleep apnea? If so, our Columbia, SC, sleep doctor Dr. Richard Bogan can offer a definitive diagnosis. Of course, in order to find out what’s causing your sleep disturbances, we will need to ask you questions about your symptoms and go through your medical history before deciding which sleep study to perform. Here are the most common types of sleep studies we offer,


This is one of the most common studies that we perform to diagnose sleep apnea. Before the study can begin, the patient is hooked up to electrodes that they will wear while they are sleeping. The electrodes will be used to measure everything from heart rate and brain waves to respiration. Most patients will get their results within 7-10 days after their test. If this test comes back positive for sleep apnea, you’ll need a second test known as a titration study.

CPAP Titration Study

Again, our technicians will hook up the same electrodes to your body that they did for your polysomnogram, but this time we will also fit you with CPAP therapy that you will wear while you sleep. As you sleep, our Columbia, SC, sleep team will be able to monitor your respiration and airways and accommodate it by adjusting the air pressure within the CPAP face mask. This will help us figure out the appropriate amount of pressure needed to keep airways open so that you can do this from the comfort of your own home.

Split-Night Test

In some instances, we may be able to perform both the polysomnogram and the CPAP titration study in one night, but this will depend on certain factors of your polysomnogram. This is something that we can discuss further with you during your sleep consultation.

Multiple Sleep Latency Test

Do you find yourself feeling exhausted throughout the day? If so you could be dealing with narcolepsy or hypersomnia. A multiple sleep latency test is performed during the day and involves having patients take five 20-minutes naps, two hours apart. During the test, we will monitor how long it takes a patient to fall asleep, which will be determined through sensors that are placed on the head and face. If you have trouble staying awake during the day or feel exhausted despite getting good sleep, then an MSLT may be recommended by our Columbia, SC, sleep team.

If you are having trouble getting quality sleep night after night, a sleep disorder could be to blame. Find out what’s causing your issues by turning to our Columbia, SC, sleep doctor Dr. Bogan for answers. Call Bogan Sleep Consultants at (803) 251-3093 to schedule a no-risk consultation.
