What is Polysomnography?
Polysomnography (PSG) is the gold standard sleep study used to diagnose Sleep Apnea and a wide range of sleep disorders. Conducted overnight, PSG continuously monitors multiple physiological parameters to provide a comprehensive assessment of sleep quality, breathing patterns, and overall sleep health.
This advanced diagnostic test helps sleep specialists accurately identify sleep-related breathing disorders and develop personalized treatment plans.
Parameters Monitored
During the study, several important body functions are recorded, including:
- Brain Activity (EEG)
- Eye Movements (EOG)
- Muscle Activity (EMG)
- Heart Rhythm (ECG)
- Airflow
- Respiratory Effort
- Oxygen Saturation (SpO₂)
- Body Position
- Leg Movements
Why PSG is Important?
PSG provides a detailed evaluation of sleep and helps diagnose various sleep disorders, including:
- Obstructive Sleep Apnea (OSA)
- Central Sleep Apnea (CSA)
- Mixed Sleep Apnea
- Insomnia-related Sleep Disorders
- Periodic Limb Movement Disorder (PLMD)
- Other Complex Sleep Disorders
Who May Need PSG?
PSG may be recommended for individuals who experience:
- Loud and persistent snoring
- Witnessed pauses in breathing during sleep
- Excessive daytime sleepiness
- Unexplained fatigue
- Suspected complex sleep disorders
- Previous inconclusive sleep test results
