Polysomnography (PSG) or Sleep Study Test
Polysomnography (PSG) is a comprehensive sleep study that monitors various physiological parameters during sleep. It is a diagnostic tool used to assess and diagnose sleep disorders.
Commonly monitored parameters include:
Electroencephalogram (EEG): Brain activity.
Electromyogram (EMG): Muscle activity.
Electrooculogram (EOG): Eye movements.
Respiratory effort: Chest and abdominal movement.
Airflow: Nasal and oral airflow.
Oxygen saturation: Blood oxygen levels.
ECG (Electrocardiogram): Heart activity.
Limb movement: To detect periodic limb movements.
Common Uses:
Diagnosing sleep disorders such as sleep apnea, insomnia, narcolepsy, and parasomnias.
Polysomnography is a valuable tool in understanding sleep patterns and diagnosing sleep-related issues. It is typically conducted under the supervision of trained sleep technologists and interpreted by sleep specialists. The information obtained from a polysomnography can guide appropriate interventions and treatment
