Polysomnography Test in Noida Indirapuram Vaishali

Sleep is an essential aspect of our lives, impacting our overall health and well-being of our body. When it comes to diagnosing sleep disorders and understanding sleep patterns during night, polysomnography, also known as sleep study test, plays a vital role.

What is Polysomnography?

Polysomnography is a diagnostic test in which sleep experts monitor and record various physiological parameters such heartbeats, Brainwaves, oxygen level and many more during sleep. It involves the simultaneous measurement of multiple signals, such as brain waves, eye movements, muscle activity, heart rate, and breathing patterns. By monitoring, these data points, polysomnography helps sleep experts analyze sleep patterns during night and identify Sleep Disorders.

When should Polysomnography be done?

Polysomnography is recommended in various scenarios that includes:

  • Identification of any major sleep disorder such as sleep apnea, insomnia, narcolepsy, restless legs syndrome, and REM sleep behavior disorder.
  • Assessment of severity of sleep-related breathing disorders, periodic limb movement disorder, and other conditions affecting sleep quality.
  • Monitoring treatment effectiveness for sleep disorders.
  • Evaluating sleep patterns and disturbances by Sleep Experts in individuals with unexplained daytime sleepiness, Fatigue and abnormal sleep behaviors.

The Five Major Sleep Disorders:

Polysomnography is proven helpful in diagnosis and treatment of several sleep disorders such as:

  • Obstructive Sleep Apnea: This condition involves repetitive, partial or complete upper airway blockages during sleep at night, resulting in breathing pauses and disrupted sleep. This condition result daytime sleepiness, fatigue, morning headache, sore throat, lack of concentration and many more problems.
  • Insomnia: Insomnia refers to persistent difficulties falling asleep, staying asleep, or experiencing disrupting sleep, leading to daytime sleepiness and fatigue.
  • Narcolepsy: Narcolepsy is characterized by excessive daytime sleepiness, sudden sleep attacks and disrupted sleep-wake cycles, often accompanied by cataplexy (sudden loss of muscle tone).
  • Restless Legs Syndrome: Restless Legs Syndrome causes an irresistible urge to move the legs, usually accompanied by uncomfortable sensations in legs, often leading to difficulty falling or staying asleep.
  • REM Sleep Behavior Disorder: In this disorder, the normal paralysis that occurs during REM sleep is absent, leading to potentially disruptive dream enactment behaviors.

what are the Stages of Sleep during Polysomnography Test?

Polysomnography captures different stages of sleep, including:

Wakefulness: The stage of being fully awake and alert.

  • Non-REM Sleep:
  • N1 (Light Sleep): The transition from waking up to sleep, characterized by slower brain waves.
  • N2 (Light Sleep): The stage where sleep spindles and K-complexes appear, and brain activity further slows down.
  • N3 (Deep Sleep): Deep sleep, also known as slow-wave sleep, characterized by slow brain waves and bodily restoration.
  • REM Sleep: Rapid Eye Movement sleep, characterized by rapid eye movements, vivid dreams and temporary muscle paralysis.

The Four Types of Sleep Patterns :

During polysomnography, various sleep patterns can be observed by sleep expert, including:

  • Normal Sleep Pattern: A balanced and uninterrupted sleep pattern characterized by a regular progression through different sleep stages.
  • Fragmented Sleep Pattern: this sleep pattern marked by frequent awakenings or disruptions, resulting in poor sleep continuity.
  • Sleep-Related Breathing Disorders Pattern: This pattern indicates the presence of sleep disorders like sleep apnea, characterized by recurrent pauses in breathing during sleep.
  • Abnormal Sleep Pattern: An irregular sleep pattern associated with sleep disorders such as insomnia, narcolepsy, or restless legs syndrome, where the sleep monitoring seems to be disrupted or abnormal.

Duration of Sleep Stages

The duration of sleep stages can vary from person to person, but generally, these time frames are being mostly followed:

  • Wakefulness: Typically occurs before falling for asleep or upon awakening from sleep.
  • N1 (Light Sleep): Lasts for about 5-10% of total sleep time.
  • N2 (Light Sleep): Accounts for approximately 45-55% of total sleep time.
  • N3 (Deep Sleep): Occurs during the first half of the night and constitutes around 15-25% of total sleep time.
  • REM sleep: Becomes more prominent during the second half of the night and comprises roughly 20-25% of total sleep time.

What is cost of polysomnography?

The cost of Polysomnography Test, also known as Sleep Study Test, can vary upon several factors. These may include the location of the center or you opt for Sleep Study at home, type of facility (hospital, sleep center, or home-based study), additional monitoring requirements and equipment, and insurance coverage if required. In Delhi NCR, the cost of Polysomnography Test can variant, with prices varying based on specific providers and services offered.

What are the most common sleep disorders?

Polysomnography Test is proven helpful identifying and diagnose various sleep disorders. Here are three common ones:

  • Sleep Apnea: Sleep apnea is a sleep disorder characterized by breath pauses and disruptive sleep during night that leads to many severe and potentially serious health consequences.
  • Periodic Limb Movement Disorder: Periodic limb movement disorder involves repetitive leg movements during sleep, leading to disruptive sleep and daytime fatigue.
  • Rapid Eye Movement (REM) Sleep Behavior Disorder: In REM sleep behavior disorder, individuals physically act out their dreams due to the presence of muscle paralysis during REM sleep. This can lead to potentially harmful behaviors and worst sleep disruptions.

Medication of Sleep Disorders

The choice of medication for sleep disorders depends on the specific sleep disorder and should be prescribed by Sleep Experts and Pulmonologist. Common classes of medications include sedative-hypnotics, such as benzodiazepines and non-benzodiazepines, antidepressants, and medications targeting specific sleep-related symptoms or underlying causes.

Polysomnography, or sleep study test, is an invaluable tool in the realm of sleep medicine. By providing detailed information about sleep architecture and detecting sleep disorders, it enables sleep experts to diagnose and guide appropriate treatment. Whether you’re in Delhi NCR or elsewhere, understanding the significance of polysomnography can lead to improved sleep health and overall well-being. If you suspect a sleep disorder, consult a sleep expert who can recommend the appropriate steps, including undergoing a polysomnography test, to help you achieve restful and rejuvenating sleep.
