Sleep Studies at Family Sleep Diagnostics
If your sleep specialists believes you may have a sleep disorder, they will order an in-lab sleep study. A in-lab sleep study requires an overnight stay in one of our sleep clinics so we can monitor your sleep.
The testing suites at Family Sleep Diagnostics offer patients a home away from home and come equipped with television and secure Wi-Fi.
There are a variety of sleep tests that we administer. Here are just a few of them:
ADULT POLYSOMNOGRAPHY, or PSG
Adult Polysomnography is a sleep test that utilizes small electrodes on the head to monitor brain waves and record sleep, as well as chin and eye movements. Velcro belts are also attached across the chest and stomach to record breathing patterns, while a nasal cannula and thermal sensor are used to monitor the flow of air through the nose. Electrodes are placed on the legs and near the heart to record limb movement and heartbeat, respectively. Finally, a pulse oximeter is placed on the finger to monitor heart rate and oxygen levels and a microphone is utilized to record snoring.
Adult Polysomnography is done without Positive Airway Pressure therapy. However, Inspire Therapy, Mandibular Advancement Therapy, or another non-PAP treatment may be analyzed.
Split Polysomnography, or PSG, is a sleep test that utilizes small electrodes on the head to monitor brain waves and record sleep, as well as chin and eye movements. Velcro belts are also attached across the chest and stomach to record breathing patterns, while a nasal cannula and thermal sensor are used to monitor the flow of air through the nose. Electrodes are placed on the legs and near the heart to record limb movement and heartbeat, respectively. Finally, a pulse oximeter is placed on the finger to monitor heart rate and oxygen levels and a microphone is utilized to record snoring.
This test is unique in that it begins by monitoring the patient through the first half of the night in order to establish a baseline and then Positive Airway Pressure is initiated and titrated for the second half if patient meets criteria. This is the most common sleep test ordered.
Titration Polysomnography, or PSG, is a study administered in order to determine the Positive Airway Pressure (PAP) needed to improve apnea and snoring. Titration PSG monitors all the same body functions as listed above for Adult PSG while the patient is using PAP Therapy throughout the entire night.
This test is unique in that it is only ordered after a patient has qualified for Positive Airway Pressure therapy and requires further analysis to achieve ideal titration. This test may also be ordered if a patient’s symptoms have returned after using PAP therapy for a time and need adjustments made to their levels during a supervised sleep.
MULTIPLE SLEEP LATENCY TESTING
Multiple Sleep Latency Testing, or MSLT, is a study executed in the daytime that measures a person’s ability to fall asleep. MLST is conducted in cooperation with a PSG study the previous night. It is used to establish how fast a person can fall asleep, specifically in the day, after a night of normal sleep. This study takes a full day to complete and involves monitoring nap opportunities every two hours.
This test may be ordered to evaluate narcolepsy or hypersomnia and involves screening for drugs. If an underlying condition (ie. moderate sleep apnea or moderate periodic limb movement) is observed, MSLT would not be conducted until the underlying condition is treated.
MAINTENANCE OF WAKEFULNESS TESTING
Maintenance of Wakefulness Test, or MWT, is a study executed to measure a person’s ability to remain awake. By utilizing electrodes, a patient is monitored during multiple trial periods. Typically, a patient will be monitored throughout 4 forty-minute periods. During each forty-minute period, they will be seated in a bed supported by a bolster pillow. The room will remain quiet and dark (besides a small nightlight) and patients are asked to refrain from any extreme behaviors that might keep them awake. This test follows a full night PSG to ensure the patient has a good night’s sleep.
MWT is often ordered for pilots or drivers, as well as patients being treated for a sleep disorder who need to document an ability to stay awake throughout difficult circumstances. This test involves screening for drugs.
