A sleep study is an overnight test designed to gather information about your sleep as part of a complete assessment. Sleep studies performed in a hospital laboratory are the gold standard test and the most accurate type of study. Home-based studies may be appropriate in certain circumstances.
During a sleep study special monitoring equipment is worn and the following are recorded:
- Breathing
- Oxygen levels
- EEG (brain wave activity) to determine sleep staging
- ECG (heart tracing) to monitor heart rate and detect arrhythmias
- Eye movements
- Chin muscle tone
- Leg movements
- Body position
- Infrared video recording
The vast majority of people get off to sleep with little difficulty during their study. Following the completion of the sleep study the data is analysed in detail by sleep scientists and examined by the sleep physician. The results are used by the sleep physician, together with your symptoms and examination findings, to arrive at a diagnosis and create a treatment plan.
Dr Chazan can arrange sleep studies in public or private hospital sleep laboratories. He also performs home-based overnight sleep studies which may be more convenient for appropriately selected patients.
