What You Can Expect from a Sleep Study

What You Can Expect from a Sleep Study

Going to sleep is supposed to leave you feeling revived and refreshed. If you’re waking up feeling tired and sluggish, a sleep disorder could be the cause. Getting to the root of what’s disturbing your sleep can be a challenge, since it can only be pinpointed while you’re asleep. 

That’s where sleep studies come in. Sleep studies provide invaluable information about sleep patterns, so you can get the treatment you need to feel rested and revived upon waking.  

At Northwest Pulmonary and Sleep Medicine in Algonquin, Illinois, Dennis Kellar, MD, and Madhu Gundavaram, MD, use sleep studies, both at home and at our comfortable, private sleep study facility, to diagnose and treat a variety of sleep disorders.

Our patients can feel confident knowing that our practice is accredited by the American Academy of Sleep Medicine (AASM), the industry gold standard in evaluating different types of sleep disorders. In this blog, our sleep experts explain what you can expect before and after a sleep study.  

Why should I get a sleep study?

Sleep provides time for your body to repair, regenerate, and regulate many different bodily functions. For example, during sleep, your heart rate and breathing slow, your blood pressure drops, and your muscles relax, giving your cells time to regenerate and repair minor and major areas of damage. 

Sleep is also essential to your health in many other ways. Sleep helps your body:

If you’re not getting an adequate amount of high-quality sleep, your overall health and well-being could be at risk. A sleep study can help you understand why you’re not sleeping well and provide a starting point for treatment.

What happens during a sleep study?

At Northwest Pulmonary and Sleep Medicine, we offer two types of sleep studies: at-home sleep studies, and studies at our private, comfortable, state-of-the-art facility. Both are noninvasive and pain-free.

If you’re eligible for an at-home sleep study, your provider gives you a machine with sensors that you attach to yourself before going to sleep. Typically, the sensors include a nasal cannula to measure airflow, a chest strap to measure breathing effort, and a pulse oximeter to measure your oxygen and pulse. 

For patients undergoing sleep studies at our AASM-accredited sleep facility, you can expect a private, hotel-like room with internet and television access. Our rooms offer full-size beds fitted with comfortable, high-quality sheets. 

Our team uses a variety of technologies to record your breathing patterns, movements, and behaviors while asleep. Our comfortable and noninvasive movement sensors track your oxygen levels, pulse, breathing rate, body movements, snoring, and eye movements.

An electroencephalogram (EEG) machine, worn over your head like a hairnet or helmet,  measures and tracks your brain wave patterns, providing us with important information about your sleep cycle, including your REM and non-REM sleep.  

What happens after a sleep study?

After your sleep study, you can continue with your normal day. The Northwest Pulmonary and Sleep Medicine team uses the time between your study and follow-up appointment to analyze the data collected during your study. 

With a diagnosis in hand, your provider creates a customized treatment plan to help you rest better and wake feeling refreshed. Your treatment plan will depend on your situation, but your options may include the following:
