Sleep Disorder Services — Sleep Lab
An estimated 70 million Americans suffer from some type of sleep disorder. If you are one of them, we can help you get the rest you need.
The purpose of Mercy Regional Health Center's Sleep Lab is to help you get the best sleep possible. An accredited, cutting-edge facility, the Sleep Lab can assess why you're having difficulty sleeping, and identify what can be done to address those problems. Ask your doctor whether you might benefit from a sleep study, or contact us to learn more.
Why the Sleep Lab?
The Sleep Lab offers a full range of services designed to evaluate, diagnose, treat and help you manage your sleep disorder.
Our licensed, experienced technicians conduct sleep studies that get to the root of your sleep troubles. The results are then interpreted by one of our board-certified neurologists or pulmonary specialists.
The Sleep Lab is accredited by the American Academy of Sleep Medicine (AASM). This accreditation means that we meet the standards and requirements of the AASM regarding quality, staffing, physician support and room sizes. It also means that you can expect the highest quality care when you visit our facility.
Our sleep studies include:
- CPAP titration
- Split-night polysomnogram
- Multi sleep latency test
As a Sleep Lab patient, you will spend the night in a comfortable, quiet room while we evaluate your sleep issues using a non-invasive test called a polysomnogram (PSG). The PSG is the basis for all other exams and is used primarily to identify and measure sleep abnormalities. This test is simply a basic study that monitors you as you sleep.
What to Expect
Through small sensors attached to key points on the body, the test measures and records:
- Brain waves
- Heart rhythms
- Muscle activity
- Breathing patterns
- Leg and eye movements
This information can reveal a lot about snoring, daytime sleepiness, unexplained headaches and severe nasal obstructions. If necessary, the Sleep Lab can also perform other types of sleep studies to diagnose and treat specific conditions once they have been identified.
The Diagnosis Process
A doctor who specializes in sleep disorders interprets the test results, makes a diagnosis, and consults with your primary care physician to create a personalized treatment program for your condition.
If the initial polysomnogram (PSG) identifies that you have obstructive sleep apnea, then the Sleep Lab will generally conduct a CPAP (continuous positive airway pressure) or bi-level titration. Very similar to the PSG, this test simply requires you to wear a mask that covers either your nose, or your nose and mouth. The mask is connected by a tube to a machine called a blower.
Throughout the exam, the technician gradually and remotely increases the amount of air or pressure generated by the blower in an effort to eliminate any obstructions. The mask and blower create a column of air in the airway, holding the airways open and eliminating the obstructive respiratory events.
The split-night polysomnogram is a combination of the simple polysomnogram and the CPAP titration. Primarily used for patients who likely have obstructive sleep apnea (OSA), this test was developed to be less time-consuming and less expensive for patients.
The first part of the exam is the simple polysomnogram. The technician watches for evidence of OSA. If the polysomnogram shows you have OSA, the CPAP titration test is run. The overall goal is to quickly identify obstructive sleep apnea and initiate treatment, all in a single night.
Multi Sleep Latency Test
The multi sleep latency test (MSLT) demonstrates how tired or sleepy an individual is during normal waking hours. Primarily used to diagnose narcolepsy, this exam requires you to undergo a simple polysomnogram (PSG) to confirm that there is no other sleep abnormality present, and more importantly to provide documentation that there was good, quality sleep.
The morning following the PSG, most of the electrodes and sensors are removed with the exception of those on the head and face. During the day, beginning two hours after awakening, you are given the opportunity to take a nap. If you fall asleep within twenty minutes, you are allowed to sleep for an additional fifteen minutes, at which point you must get up. If, however, you do not fall asleep within twenty minutes, you must get up again. This process repeats itself every two hours for five naps.
