What Exactly is a PSG Test in Delhi?

A Polysomnography (PSG) test is the gold standard diagnostic procedure for comprehensive sleep disorder evaluation. This sophisticated overnight monitoring system simultaneously records multiple physiological parameters including brain waves (EEG), eye movements (EOG), muscle activity (EMG), heart rhythm (ECG), respiratory airflow, chest and abdominal effort, oxygen saturation (SpO2), and body position throughout your sleep cycle. Unlike basic sleep tracking devices, PSG captures detailed sleep architecture data — analyzing REM stages, non-REM phases, sleep latency, arousal index, and respiratory disturbance index (RDI). This enables sleep specialists to diagnose conditions like obstructive sleep apnea (OSA), central sleep apnea, periodic limb movement disorder (PLMD), REM behavior disorder, and various parasomnias with clinical precision.

Who Should Consider a PSG Test in Delhi?

You may benefit from polysomnography if you experience:

• Sleep-disordered breathing symptoms like loud snoring, witnessed apneas, or gasping episodes
• Excessive daytime sleepiness despite adequate sleep duration (Epworth Sleepiness Scale >10)
• Unexplained morning headaches or dry mouth upon awakening
• Restless leg syndrome or periodic limb movements disrupting sleep
• Suspected narcolepsy with sudden sleep attacks or cataplexy episodes
• REM behavior disorder involving dream enactment or sleep talking
• Chronic insomnia unresponsive to conventional treatments
• Cardiovascular complications potentially linked to sleep apnea
• Pre-surgical evaluation for weight loss procedures or cardiac interventions
