What should I expect?
Once you arrive at Lexington Sleep Solutions, we’ll show you to your private bedroom. Each room is equipped to monitor and record your breathing, heart rate, oxygen levels and brain wave activity during sleep.
A camera is used to observe your sleep throughout the night and provide diagnostic information. An intercom will be on at all times so you can speak to the technologist in a monitoring room nearby.
The following morning the monitors will be removed, and you’ll start your daily routine. It will take several days to have the complete results of your study. A clinic appointment may be scheduled to review the results to determine what treatment is necessarySleep Disorders We Treat

What is it?
A common condition defined as a pause in breathing while sleeping that lasts ten seconds or longer and occurs occur 20 to 30 times in an hour. It can be life threatening.
What causes it?
Most commonly, air does not flow into your lungs through your mouth or nose, causing the amount of oxygen in your blood to drop.
What are the symptoms?
Symptoms may include frequent waking episodes and a “choking” or “gasping” sound.
Snoring

Snoring occurs when the airway has some form of obstruction.

Although it seems common, snoring can be a sign of a more serious breathing problem. Snoring can also interfere with the quality of sleep due to frequent waking episodes, which may lead to sleepiness during the day.
