Understanding Polysomnography
Polysomnography (PSG) is a comprehensive sleep study that records multiple body functions during sleep. It is the gold standard for diagnosing sleep disorders such as sleep apnea, narcolepsy, restless leg syndrome, and other conditions that affect sleep quality.
What Does a Sleep Study Measure?
During a polysomnographic study, the following parameters are typically recorded:
- Electroencephalogram (EEG) - Brain wave activity to determine sleep stages
- Electrooculogram (EOG) - Eye movements
- Electromyogram (EMG) - Muscle activity
- Electrocardiogram (ECG) - Heart rate and rhythm
- Respiratory monitoring - Airflow, respiratory effort, and oxygen levels
- Leg movements - Periodic limb movements
The Scoring Process
Sleep study scoring is the process of analyzing the recorded data to identify sleep stages, breathing events, arousals, and other significant findings. This requires expertise and attention to detail to ensure accurate diagnosis.
At Registered Sleepers, all scoring is performed by experienced Registered Polysomnographic Technologists who follow current guidelines approved by the American Academy of Sleep Medicine (AASM).
