This overnight sleep study is the most comprehensive way of diagnosing sleep apnea.
The Full PSG (Polysomnography) Sleep Study involves a test, known as ‘polysomnography’ that records the following detailed information during the night:
- Brain activity (electroencephalography)
- Muscle tone (electromyography)
- Movement of your chest and abdomen
- Airflow through your mouth and nose
- Heart rate and blood oxygen levels (pulse oximetry)
- Heart electrocardiography
None of these procedures are painful. Sound recording and video equipment may also be used.
Once the tests have been completed, a trained PSG technologist will score the readings and provide you with the result. Your report will let you know how much your condition interrupts your sleep and impacts your health.
A full PSG study can also detect other forms of sleep disorders such as insomnia, periodic leg movement syndrome. The electrodes can record up to 60 channels of recording such as electroencephalogram (EEG), electro-oculogram (EOG), electrocardiogram (EKG), electromyogram (EMG).
