Sleep study is an examination method that is generally carried out if you experience sleep disorders, whether it is difficult to sleep or often wake up during sleep at night. This examination aims to evaluate sleep patterns and determine the type of sleep disturbance that occurs

Sleep study or polysomnography is done by recording brain waves, blood oxygen levels, heart and breathing rates, and eye and leg movements while you are asleep. Through this examination, the doctor can also assess how long it takes to fall asleep, the length of time you sleep, and the quality of your sleep.

Types of Sleep Disorders that Can Be Detected by Sleep Study

Sleep study can generally be done to diagnose various conditions or disorders in sleep patterns and quality, such as:

  • Sleep apnea
  • Restless legs syndrome
  • Insomnia
  • Narcolepsy
  • sleep walking disorder
  • Circadian rhythm disorders, namely disturbances in the body clock that make it difficult for sufferers to sleep, have difficulty falling asleep, often wake up when sleeping, or wake up too early and can't sleep anymore

You may be advised by a doctor to undergo a sleep study if you have the following complaints:

  • Sleep with loud snoring
  • Wake up suddenly gasping for breath
  • Tired and sleepy during the day
  • Restless while sleeping
  • Difficulty sleeping or taking a long time to fall asleep
  • Sleep is not sound or not sound enough
  • Often fall asleep suddenly without knowing the place

Different Types of Sleep Study

There are several types of sleep study examinations, namely:

1. Polysomnogram (PSG)

PSG aims to monitor your sleep patterns and bodily functions, such as breathing patterns, blood oxygen levels, heart rhythm, and limb movements. This examination is generally carried out at night, while you are asleep.

2. Multiple Sleep Latency Test (MSLT)

MSLT is done after you have done the PSG check. This test can help your doctor make a diagnosis of narcolepsy and assess your level of daytime sleepiness.

The MSLT aims to measure how quickly you fall asleep in quiet situations during the day. In addition, this test also monitors how fast and how often you fall asleep.

3. Polysomnogram and CPAP (Continuous Positive Airway Pressure)

This type of sleep study was conducted for 2 nights. A polysomnogram with CPAP is often done when the results of your PSG examination show that you have sleep apnea.

After being diagnosed with sleep apnea, you may be advised by a doctor to use a CPAP device while sleeping so that your oxygen needs are met.

Well, the polysomnogram examination followed by the CPAP test aims to determine the appropriate CPAP machine settings and the amount of oxygen that suits your needs.

Preparation for Sleep Study

Sleep study checks can be done in hospitals or clinics that have this examination facility. Before undergoing a sleep study, you will usually be asked to make the following preparations:

  • Do not consume caffeine in any form, such as coffee, tea, soft drinks or chocolate, after lunch on the day of the examination
  • Do not consume alcoholic beverages
  • Cleaning or washing hair from gel or other hair styling products so that the tool that will be installed on the head during sleep study can function properly
  • Do not sleep during the day when the sleep study examination is carried out
  • Tell your doctor about any medicines you are taking, because these medicines may need to be stopped temporarily

You are also encouraged to bring a friend or family member, and bring your usual pajamas or sleepwear, books, magazines, or special pillows so that you feel comfortable during the examination.

Things That Happened During Sleep Study

You will be placed in a private bedroom equipped with a private bathroom, camera and microphone. Cameras are installed so doctors can see what's happening while you're asleep, while cameras and microphones are attached so doctors can communicate with you during the sleep study.

When the sleep study begins, the doctor will attach a sensor device to the face, scalp, chest, and limbs. Through this device, electrical signals in the nerves of the brain will be monitored while you are asleep.

During the sleep study, the doctor will sit near you to monitor:

  • brain waves
  • eye movement
  • Heart rate and rhythm
  • Blood pressure
  • Breathing pattern
  • Blood oxygen level
  • Body position
  • chest and stomach movement
  • Leg movement
  • Snoring and other noises you may make while sleeping

Various examination tools may be attached to your body for 1 night. However, the doctor will remove the examination equipment the next day, after the sleep study examination is completed. After that, you can return to your normal daily activities.

Sleep Study Examination Results

Sleep study data usually includes information about your sleep patterns, such as:

  • Brain waves and eye movements can help assess sleep stages and identify sleep disorders, such as narcolepsy
  • Changes in heart and breathing rates and changes in blood oxygen during sleep can be a sign of sleep apnea
  • Foot movements often interfere with sleep quality may indicate extreme movement disorders
  • Unusual movement or behavior during sleep may be a sign of REM sleep behavior disorder or sleepwalking disorder

In addition, the results of the sleep study test also record how long you sleep, how often you wake up, whether you have difficulty breathing, whether you snore, and your body position when you sleep.

If you find it difficult to sleep or have complaints related to sleep disturbances that have been prolonged and interfere with your daily activities, consult a doctor to undergo a sleep study.
