Sleep Study Diagnosis in Nashik – Dr. Mutha Chest & Sleep Center

At Dr. Mutha Chest & Sleep Center, we specialize in advanced Sleep Study Diagnosis in Nashik, helping patients identify and manage sleep-related disorders like Obstructive Sleep Apnea Syndrome (OSAS). Our lab is equipped with modern polysomnography (PSG) tools to assess and record vital sleep-related physiological functions in a controlled, overnight setting.

What is a Sleep Study (Polysomnography)?

Polysomnography (PSG) is considered the gold standard for Sleep Apnea Diagnosis in Nashik. It’s a comprehensive overnight test that records multiple body functions such as brain activity, breathing patterns, blood oxygen levels, heart rate, and body movements during sleep.

PSG helps in diagnosing:

• Obstructive Sleep Apnea

• Central Sleep Apnea

• Mixed Sleep Apnea

• REM-related parasomnias

• Periodic Limb Movement Disorder

• Bruxism

• Sleep Hypoventilation

If you’re experiencing excessive daytime sleepiness, loud snoring, pauses in breathing during sleep, or fatigue even after a full night’s rest, a Sleep Study Test in Nashik may be recommended.

Parameters Monitored During Sleep Study

We conduct PSG by simultaneously recording multiple physiological parameters:

• EEG (Electroencephalography): Records brain wave activity to determine sleep stages

• EOG (Electrooculography): Monitors eye movements to track REM and sleep onset

• EMG (Electromyography): Detects chin muscle activity for REM atonia, and anterior tibialis muscle for leg movements

• Thermistor & Pressure Transducer: Monitor nasal/oral airflow and identify apneas or hypopneas

• Pulse Oximetry: Monitors oxygen saturation

• Respiratory Effort Sensors: Track thoracic and abdominal movements

• Electrocardiography (ECG): Captures heart rhythm during sleep

• Video Monitoring: Helps correlate physical movements with recorded data

Sleep Disorders Diagnosed by PSG

Our Sleep Lab in Nashik helps detect and differentiate between various sleep disorders:

1. Obstructive Sleep Apnea (OSA)

• Reduction in airflow >90% lasting at least 10 seconds

• Associated with increasing respiratory effort and oxygen desaturation

• Diagnosed with both thermistor and pressure transducer data

2. Central Sleep Apnea

• Absence of airflow and respiratory effort for >10 seconds

• Indicates a dysfunction in the brain’s control over breathing

3. Mixed Apnea

• Starts as central (no effort), ends as obstructive (effort returns)

• Associated with drop in oxygen saturation

4. Hypopnea

• ≥30% airflow reduction with ≥3% oxygen desaturation or arousal

• Scored as obstructive or central based on effort and airflow changes

5. Periodic Limb Movement Disorder

• Repetitive leg jerks (0.5–10 seconds) with a minimum 4 events per hour

• Identified using anterior tibialis EMG

6. Cheyne-Stokes Respiration

• Cyclic pattern of crescendo-decrescendo breathing

• Minimum 3 consecutive cycles with apnea/hypopnea components

7. Sleep-Related Hypoventilation

• CO₂ >50 mmHg for >25% of total sleep time

• Measured via end-tidal or transcutaneous CO₂ sensors

8. Bruxism

• Detected via chin EMG with ≥3 bursts of activity

• Commonly associated with stress and sleep arousals

When is a Sleep Study Recommended?

Your pulmonologist may recommend a Sleep Apnea Test in Nashik if you have:

• Loud, habitual snoring

• Episodes of stopped breathing observed during sleep

• Persistent fatigue or sleepiness during the day

• Difficulty concentrating

• Morning headaches

• High blood pressure or arrhythmia

• Depression or mood changes

• Suspected Obstructive Sleep Apnea or Narcolepsy

We also recommend PSG testing before and after CPAP therapy to evaluate its effectiveness in sleep apnea management.
