Polysomnography (Sleep Study) Test in Noida

Comprehensive Overnight Sleep Study for Accurate Diagnosis of Sleep Disorders

Sleep plays a vital role in maintaining overall physical and mental health. Persistent snoring, excessive daytime sleepiness, interrupted sleep, breathing pauses during sleep, and other sleep-related symptoms may indicate an underlying sleep disorder. Polysomnography (PSG), commonly known as a Sleep Study, is the gold-standard diagnostic test used to evaluate sleep disorders by monitoring multiple body functions during sleep, including brain activity, breathing, oxygen levels, heart rate, eye movements, muscle activity, and body movements.

At Yatharth Hospital, our experienced pulmonologists, neurologists, ENT specialists, and sleep medicine experts perform advanced overnight polysomnography using modern sleep monitoring systems. Our comprehensive evaluation helps accurately diagnose sleep disorders and develop personalized treatment plans to improve sleep quality and overall health.

What is Polysomnography (Sleep Study)?

Polysomnography is a non-invasive overnight diagnostic test that records multiple physiological parameters while you sleep. The test evaluates your sleep stages, breathing patterns, oxygen saturation, heart rhythm, muscle activity, eye movements, and body position to identify sleep-related disorders. It is considered the gold standard for diagnosing Obstructive Sleep Apnea (OSA) and several other sleep disorders.

Why is a Sleep Study Performed?

A sleep study may be recommended if you have symptoms suggestive of a sleep disorder, including:

• Loud, habitual snoring
• Breathing pauses during sleep
• Excessive daytime sleepiness
• Difficulty falling or staying asleep
• Unexplained fatigue
• Restless sleep
• Morning headaches
• Sudden sleep attacks
• Unusual movements or behaviors during sleep
• Frequent nighttime awakenings
• Suspected sleep-related breathing disorders

Conditions Diagnosed with Polysomnography

A sleep study helps diagnose:

• Obstructive Sleep Apnea (OSA)
• Central Sleep Apnea
• Mixed Sleep Apnea
• Narcolepsy
• Insomnia (when clinically indicated)
• Restless Legs Syndrome (RLS)
• Periodic Limb Movement Disorder (PLMD)
• REM Sleep Behavior Disorder
• Parasomnias (sleepwalking, sleep talking, night terrors)
• Circadian Rhythm Sleep Disorders
• Nocturnal Seizures

Who Should Undergo a Sleep Study?

You may benefit from polysomnography if you:

• Snore loudly every night
• Experience witnessed breathing pauses during sleep
• Wake up gasping or choking
• Feel excessively sleepy during the day
• Have resistant hypertension
• Are overweight or obese with symptoms of sleep apnea
• Have heart disease associated with sleep disturbances
• Experience abnormal movements during sleep
• Have unexplained poor sleep quality

What Does a Sleep Study Measure?

During polysomnography, specialized sensors monitor:

• Brain waves (EEG)
• Eye movements (EOG)
• Muscle activity (EMG)
• Heart rhythm (ECG)
• Airflow through the nose and mouth
• Breathing effort
• Blood oxygen saturation (SpO₂)
• Snoring
• Body position
• Leg movements
• Sleep stages (NREM and REM sleep)

Benefits of Polysomnography

A sleep study offers several advantages:

• Accurate diagnosis of sleep disorders
• Early detection of sleep apnea
• Comprehensive overnight monitoring
• Non-invasive and painless procedure
• Personalized treatment planning
• Improved quality of sleep
• Reduced risk of untreated sleep apnea complications
• Better cardiovascular and metabolic health
• Enhanced daytime alertness and quality of life

Preparing for a Sleep Study

Your doctor may advise you to:

• Avoid caffeine and alcohol on the day of the test
• Avoid daytime naps before the study
• Continue regular medications unless instructed otherwise
• Wash your hair and avoid hair products, lotions, or oils before the test
• Bring comfortable nightwear and personal toiletries
• Inform your doctor about any medications you are taking

How is a Polysomnography Test Performed?

Step 1: Arrival at the Sleep Laboratory

You arrive at the sleep center in the evening and are assigned a comfortable private room.

Step 2: Sensor Placement

A trained sleep technologist places small sensors on your scalp, face, chest, abdomen, legs, and fingers using adhesive pads.

Step 3: Overnight Monitoring

You sleep normally while specialized equipment continuously records your physiological parameters throughout the night.

Step 4: Data Analysis

The recorded data are analyzed by trained sleep technologists and interpreted by a sleep medicine specialist.

Step 5: Treatment Planning

Based on the findings, your doctor discusses the diagnosis and recommends the most appropriate treatment, which may include lifestyle changes, CPAP therapy, oral appliances, medications, or further evaluation.

Recovery After the Test

Polysomnography is a safe outpatient test.

Patients can generally expect:

• No recovery time
• Return home the following morning
• Resume normal daily activities immediately
• Results available after detailed analysis
• Follow-up consultation to discuss treatment recommendations

Is Polysomnography Safe?

Yes. Polysomnography is a safe, painless, and non-invasive diagnostic test. The most common minor issue is mild skin irritation from the adhesive used to attach the sensors.
