Aster CMI Hospital's Sleep Lab offers comprehensive diagnostic and treatment services for sleep disorders. Utilizing advanced technology and a team of experienced sleep specialists, our Sleep Lab provides accurate assessments and effective management plans to improve patients' sleep quality and overall health. Here are the specialized services provided:
Complete and Split Overnight Polysomnography
Polysomnography is the gold standard for diagnosing sleep disorders. This overnight test records multiple physiological parameters during sleep, including brain activity (EEG), eye movements (EOG), muscle activity (EMG), heart rate (ECG), respiratory effort, airflow, and oxygen saturation.
Complete Overnight Polysomnography
- Purpose: Comprehensive evaluation of sleep architecture, sleep stages, and disruptions.
- Indications: Diagnosing sleep apnea, restless legs syndrome, periodic limb movement disorder, narcolepsy, insomnia, and other sleep-related conditions.
- Procedure: The patient stays overnight in the Sleep Lab, where sensors are attached to monitor various physiological functions throughout the night. The data collected helps identify abnormalities in sleep patterns and physiological processes.
Split-Night Polysomnography
- Purpose: Combines diagnostic evaluation and treatment initiation in one night.
- Indications: Typically used for diagnosing and initiating treatment for moderate to severe obstructive sleep apnea (OSA).
- Procedure: The first part of the night involves standard diagnostic polysomnography. If OSA is detected, continuous positive airway pressure (CPAP) therapy is introduced during the second half of the night to determine the optimal pressure setting for treatment.
Multiple Sleep Latency Test (MSLT)
The Multiple Sleep Latency Test (MSLT) measures the time it takes for a person to fall asleep in a quiet environment during the day. It is used to assess daytime sleepiness and diagnose conditions like narcolepsy and idiopathic hypersomnia.
Purpose:
- Evaluate the degree of daytime sleepiness.
- Diagnose narcolepsy by measuring the occurrence of sleep-onset REM periods (SOREMPs).
Procedure:
- The test is conducted the day after an overnight polysomnography to ensure the patient had adequate sleep the night before.
- The patient takes a series of five scheduled naps, each lasting 20 minutes, at two-hour intervals throughout the day.
- The time it takes to fall asleep and the stages of sleep achieved during each nap are recorded and analyzed.
CPAP Titration with Sleep Study
Continuous Positive Airway Pressure (CPAP) titration is a specialized sleep study used to determine the optimal pressure settings for CPAP therapy in patients with obstructive sleep apnea (OSA). CPAP therapy involves using a machine that delivers a constant stream of air through a mask to keep the airways open during sleep.
Purpose:
- Identify the appropriate CPAP pressure needed to eliminate apneas, hypopneas, snoring, and other respiratory disturbances during sleep.
- Ensure the patient achieves restful and uninterrupted sleep with CPAP therapy.
Procedure:
- The patient undergoes an overnight sleep study while wearing a CPAP mask connected to a CPAP machine.
- The CPAP pressure is gradually adjusted throughout the night based on the patient's respiratory patterns and oxygen levels.
- Data is collected to determine the pressure setting that effectively prevents airway collapse and normalizes breathing.
Aster CMI Hospital's Sleep Lab provides advanced diagnostic and therapeutic services to address a wide range of sleep disorders. Through complete and split overnight polysomnography, multiple sleep latency tests, and CPAP titration with sleep study, our expert team ensures accurate diagnosis and effective treatment plans. By leveraging state-of-the-art technology and specialized knowledge, we are committed to improving patients' sleep health and overall well-being.
