Overnight Sleep Study

Also called a Polysomnogram or PSG, a standard sleep study in one of our centers includes the following:
EEG (electroencephalogram) – monitors brain activity to document sleep stages
EOG (electrooculogram) – measures eye movement
EMG (electromyogram) – measures muscle activity for monitoring muscle tone as well as body movement, especially limbs
EKG (electrocardiogram) – monitors heart activity
Respiratory Airflow – measures airflow from nose and mouth to document respiratory disturbances
Respiratory Effort – monitors chest wall and abdominal movement to help determine specific respiratory disturbances
Pulse oximetry – measures the oxygen saturation level to distinguish changes during respiratory events
Snoring – monitors vibration of throat to determine snoring episodes
Body Position – monitors the effect of sleep position on sleep and breathing
Other parameters as determined by physician
Treatments for sleep and breathing disorders such as sleep apnea, including the administration of positive airway pressure (PAP) and nocturnal oxygen are frequently initiated during a PSG.
During a sleep study, the technologist is in constant video and audio contact with the patient, providing a safe, supportive environment with minimal anxiety. Our diagnostic rooms have been designed to promote a relaxing atmosphere and a pleasant patient experience so that patients can undergo a full sleep diagnostic procedure, wake up and start the day with minimal disruption to their lives.
Pediatric Sleep Study
Also called a pediatric polysomnogram or PSG. Children require special attention when undergoing a sleep study. At The Sleep Center of Nevada, we provide one-to-one care, meaning that every child has their own fully qualified sleep technician to oversee their visit with us; from arriving at the lab, to waking up the next morning. The ‘unknown’ can be more frightening for the parents than the child, so our staff members are ready to answer questions before, during, and after the test.
The following are performed in our pediatric center:
Overnight Sleep Studies
Diagnostic polysomnogram
Overnight therapy
CPAP
Bi-level PAP
Multiple Sleep Latency Test (MSLT)
Multiple Sleep Latency Test
Also called a “Nap Test”, the multiple sleep latency test (MSLT) is the standard way to quantify sleepiness and diagnose disorders of excessive sleepiness. An overnight diagnostic sleep test called a polysomnogram (PSG) is required the night prior to the daytime MSLT. After the PSG is complete, a series of nap tests are spread out over the following day. After being asked to try to fall asleep for each nap test, sensors on the head and chest record your brain wave activity, eye movements, muscle contractions and heart activity to accurately detect if you fall asleep. The information we collect during your study is reviewed and analyzed by our sleep specialists.
