The DoctorsChoice Sleep Solutions Sleep Test is a Polysomnography (PSG) study performed while the patient sleeps in the secure comfort of their own home. Universally, PSG is recognized as the "gold standard" for diagnosing sleep disorders. The PSG measures the following parameters:
Electroencephalogram (EEG) - The EEG monitors brainwaves that can be used to determine the level of sleep or wakefulness.
Electro-oculogram (EOG) - The EOG measures eye movement. Since eyes typically move side-to-side in REM, this measurement helps determine the duration of REM sleep.
Electromyogram (EMG) - The EMG measures muscle movements. The chin EMG help determine the duration of REM sleep while leg EMG is used to detect "restless leg" syndrome.
Oral and Nasal Air Flow - Used to measure the size and frequency of breaths during sleep.
Chest and Abdominal Movement - These movements are used in conjuction with airflow to help determine if apneas are obstructive or central in nature.
Snoring Intensity - Used to quantify the degree and intensity of snoring.
Oximetry - This measures the amount of oxygen in the blood.
Body Position - This records the body position. Some people experience more severe apneas in certain sleeping positions.
Audio and Video - Both audio and visual are monitored during the entire sleep study.
