Polysomnography records your brain waves, the oxygen level in your blood, and your heart rate and breathing during sleep. It also measures eye and leg movements.</p>\n<p>Context: This section provides an overview of polysomnography, defining it as a sleep study used to diagnose sleep disorders and listing the key parameters it records: brain waves, blood oxygen level, heart rate, breathing, and eye and leg movements.</p>\n<hr>\n<p>Polysomnography monitors your sleep stages and cycles. It can identify if or when your sleep patterns are disrupted and why.</p>\n<p>The typical process of falling asleep begins with a sleep stage called non-rapid eye movement, also known as NREM, sleep. During this stage, brain waves slow down. This is recorded during a sleep study with a test called an electroencephalogram, also known as an EEG.</p>\n<p>After an hour or two of NREM sleep, brain activity picks up again. This sleep stage is called rapid eye movement, also known as REM, sleep. Your eyes quickly move back and forth during REM sleep. Most dreaming occurs during this stage of sleep.</p>\n<p>You typically go through multiple sleep cycles a night. You cycle between NREM and REM sleep in about 90 minutes. But sleep disorders can interfere with this sleep process.</p>\n<p>Context: This section explains why polysomnography is done, focusing on monitoring sleep stages and cycles (NREM and REM) to identify disruptions and their causes. It details the typical sleep cycle process.</p>\n<hr>\n<p>Don't consume drinks or food containing alcohol or caffeine during the afternoon and evening before a sleep study. Alcohol and caffeine can change your sleep patterns. They may make symptoms of some sleep disorders worse. Also don't nap in the afternoon before a sleep study.</p>\n<p>You may be asked to bathe or shower before your sleep study. But don't put on lotions, gels, colognes or makeup before the test. They can interfere with the test's sensors, called electrodes.</p>\n<p>For a home sleep apnea test, the equipment is delivered to you. Or you might pick up the equipment at your healthcare professional's office. You'll be given instructions on how to use the equipment. Ask questions if you are not sure about how the test or equipment works.</p>\n<p>Context: This section outlines the preparation process for a sleep study, including avoiding alcohol and caffeine, not napping, and instructions regarding bathing, lotions, and handling equipment for home sleep apnea tests.</p>\n<hr>\n<h3>During polysomnography</h3>\n<p>If you're having a sleep study in a sleep center, you'll arrive in the evening and stay overnight. You can bring items you use for your bedtime routine. You also can sleep in your own nightclothes.</p>\n<p>If you're having a home sleep apnea test, follow your regular bedtime schedule. You'll need to place the sensors on your body and turn on the machine according to the instructions you've been given. Your healthcare professional may ask you to keep a sleep log.</p>\n<p>If you're at a sleep center, the room where polysomnography is done is similar to a hotel room. It's dark and quiet during the test. You won't share the room with anyone else. Each room has its own bathroom.</p>\n<p>The sleeping area will typically have a low-light video camera. This allows the polysomnography technologists to see what's happening in the room when the lights are out. It also has an audio system. This allows them to talk to you and hear you from their monitoring area outside the room.</p>\n<p>After you get ready for bed, one of the technologists will place the sensors. They're applied to your scalp, temples, chest and legs using a mild adhesive such as glue or tape. The sensors are connected by wires to a computer. The wires are long enough to let you move around in bed. A small clip also is placed on your finger or ear. This monitors the level of oxygen in your blood.</p>\n<p>While you sleep, a technologist monitors your:</p>\n<ul>\n<li>Brain waves.</li>\n<li>Eye movements.</li>\n<li>Heart rate.</li>\n<li>Breathing pattern.</li>\n<li>Blood oxygen level.</li>\n<li>Body position.</li>\n<li>Chest and belly movement.</li>\n<li>Limb movement.</li>\n<li>Snoring and other noises.</li>\n</ul>\n<p>The technologists monitor you during the night. If you need help, you can talk to them through the monitoring equipment. They can come into the room to free up the wires if you need to get up.</p>\n<p>During the study, the technologist may have you try a positive airway pressure (PAP) machine for sleep apnea. This is a device that consists of a tight-sealing nosepiece or face mask through which a gentle stream of air is delivered to help you breathe.</p>\n<p>Continuous positive airway pressure (CPAP) is one type of PAP machine. CPAP devices deliver a constant stream of air that keeps the airway passages open while you sleep.</p>\n<p>For some people, bilevel positive airway pressure (BPAP) machines may be a more comfortable choice. These devices deliver more pressure while you're breathing in, and lower pressure when you exhale.</p>\n<p>You may have the opportunity to try on a PAP device before the sleep study begins. This makes you familiar with the device if the technologist suggests you try it later in the night. If necessary, oxygen also may be used during the study to help your breathing.</p>\n<p>Although you probably won't fall asleep as easily or sleep as well at the sleep center as you do at home, this usually doesn't affect the test results. A full night's sleep isn't required to obtain accurate polysomnography results.</p>\n<p>Context: This section details what patients can expect during polysomnography, both at a sleep center and for home tests. It describes the environment, the placement of sensors (electrodes) on the scalp, chest, and legs, the monitoring process by technologists, and the potential use of PAP machines or oxygen. It also mentions that a full night's sleep is not required for accurate results.</p>\n<hr>\n<h2>Results</h2>\n<p>The measurements recorded during a sleep study provide a great deal of information about your sleep patterns. For example:</p>\n<ul>\n<li><strong>Brain waves and eye movements</strong> during sleep can help your healthcare team assess your sleep stages. This helps identify disruptions in the stages. These disruptions may occur due to sleep disorders such as narcolepsy or REM sleep behavior disorder.</li>\n<li><strong>Heart and breathing rate changes and changes in blood oxygen</strong> that aren't typical during sleep may suggest sleep apnea.</li>\n<li><strong>Using PAP or oxygen</strong> can let your healthcare professional know which device settings work best for you. This helps if your healthcare professional would like to prescribe the device for home use.</li>\n<li><strong>Frequent leg movements</strong> that disrupt your sleep may mean you have periodic limb movement disorder.</li>\n<li><strong>Movements or behaviors during sleep</strong> may be signs of REM sleep behavior disorder or another sleep disorder.</li>\n</ul>\n<p>The information gathered during a sleep study is evaluated first by a polysomnography technologist. The technologist uses the data to chart your sleep stages and cycles. Then the information is reviewed by your healthcare professional.</p>\n<p>If you've had a home sleep apnea test, your healthcare professional reviews the information collected during the test. It may take a few days or weeks to get your results.</p>\n<p>At a follow-up appointment, your healthcare professional reviews the results with you. Based on the data gathered, your healthcare professional discusses any treatment or further evaluation that you may need.</p>\n<p>If you've had a home sleep apnea test, sometimes the results don't provide enough information. If this happens, your healthcare professional may recommend a sleep study in a sleep center.</p>\n<p>Context: This section explains how the results of a sleep study are interpreted. It details what different measurements (brain waves, eye movements, heart/breathing rate, oxygen levels, leg movements) can indicate about sleep disorders. It also describes the roles of the polysomnography technologist and the healthcare professional in evaluating and discussing the results, and the process for follow-up appointments. It also mentions that home sleep apnea tests might sometimes require a follow-up sleep center study.</p>\n</details>\n<details><summary>Searched with Kagi<p></p>\n<ul>\n<li>sleep study equipment sensors electrodes polysomnography</li>\n<li>sleep technologist training certification responsibilities</li></ul></summary><br>\n Sources (10):<br>\n<strong>Polysomnography (sleep study)</strong><br>\n<a href=\"https://www.mayoclinic.org/tests-procedures/polysomnography/about/pac-20394877\" target=\"_blank\">https://www.mayoclinic.org/tests-procedures/polysomnography/about/pac-20394877</a><br>\nJan 01, 2025 Polysomnography, known as a sleep study, is a test used to diagnose sleep disorders.

Backup electrodes should also be placed to allow for the display of F3/M2, C3/M2, and O1/M2 if there is a malfunction with the electrodes used for the recommended derivations. EMG measures the submentalis muscle activity of the chin, essential for the identification of rapid eye movement (REM) sleep. Another set EMG electrodes record anterior tibialis activity to evaluate for periodic limb movements of sleep (PLMS).<div class=\"math-box\"><math xmlns=\"http://www.w3.org/1998/Math/MathML\" display=\"block\"><mrow><mn>5</mn></mrow></math></div> Left and right eye EOGs measure the change in the electrical field potential between the cornea (positive) and retina. The recommended derivations are E1-M2 and E2-M2. EOGs are used to identify the waking eye movements, slow rolling eye movements of drowsiness into stage N1, and the fast eye movements of stage R (called stage R rather than REM when scoring PSGs). <p></p>\n<p>Context: This section describes the specific electrode placements for EEG according to the international 10-20 system and the function of EMG and EOG electrodes in identifying sleep stages.</p>\n<hr>\n<h2>Normal and Critical Findings</h2>\n<p>The essential normal findings for a polysomnogram (PSG) are the sleep stages, which are crucial to interpretation. Sleep stage scoring is based on EEG, EOG, and submental EMG criteria. Sleep stage scoring was initially being detailed by Rechtschaffen and Kales (R&K) but has since been replaced by the AASM scoring manual.</p><div class=\"math-box\"><math xmlns=\"http://www.w3.org/1998/Math/MathML\" display=\"block\"><mrow><mn>20</mn></mrow></math></div> The AASM manual is mostly consistent with the original sleep scoring manual by Rechtschaffen and Kales and is regularly updated.<p></p>\n<p>The AASM scoring manual uses new nomenclature for the wake and sleep referred to as stage W for wake, stage N1, N2, and N3 for the non-rapid eye movement (NREM) stages of sleep, and stage R for REM sleep. Stage N3 replaces stages 3 and 4 in the new classification. Sleep is staged in 30-second sections, known as epochs. Traditionally, PSGs were recorded on paper, and an epoch of sleep was a standardized length of paper given standard recording time. Today, digital PSG has virtually replaced recording on paper, and sleep is scored in sequential epochs that can be manipulated on the screen. If more than one sleep stage occurs in an epoch, the epoch is generally scored based on the sleep stage occupying most of the epoch.</p><div class=\"math-box\"><math xmlns=\"http://www.w3.org/1998/Math/MathML\" display=\"block\"><mrow><mn>21</mn></mrow></math></div>\n<p></p>\n<p>To identify the sleep stage in an epoch, the EEG plays a central role. The EEG demonstrates several recognizable wave patterns from wake through the stages of sleep. These wave patterns are described in terms of frequency, amplitude, and morphology. Frequencies include:</p>\n<ul>\n<li>Alpha 8 to 13 Hz</li>\n<li>Beta > 13 Hz</li>\n<li>Theta 4 to 7.99 Hz</li>\n<li>Delta < 4 Hz</li>\n</ul>\n<p>Amplitude is a measure of the voltage of the EEG waves and varies across different sleep stages. The overall morphology of the waves can also provide insight into the sleep stage. For example, K-complexes and sleep spindles occur in N2 sleep. K-complexes are waves with a sharp initial negative deflection, followed by a positive deflection typically with maximal amplitude in the frontal derivations. Sleep spindles are sinusoidal 11-16 Hz waves lasting at least 0.5 seconds with their maximal amplitude generally in the central derivations. Sawtooth waves, which are 2-6 Hz waves with a serrated appearance with maximal amplitude in the central leads, may be seen during or before stage R.</p>\n<p>Stage W scoring on a PSG depends on whether the patient has their eyes open or closed. With eyes open, the EEG demonstrates low amplitude mixed-frequency (LAMF) waves predominantly 4-7 Hz. With eyes closed, the EEG demonstrates an alpha (posterior dominant) rhythm in most patients. Alpha rhythm is generally most prominent in the occipital leads. The EOG shows blinking, reading eye movements or irregular, conjugate, sharply peaked rapid eye movements. EMG shows a high chin tone. Stage W is scored when greater than 50% of an epoch is alpha with patterns consistent with the above.</p><div class=\"math-box\"><math xmlns=\"http://www.w3.org/1998/Math/MathML\" display=\"block\"><mrow><mn>21</mn></mrow></math></div>\n<p></p>\n<p>Stage N1 is the transition from wakefulness into sleep.

There are usually no eye movements on EOG. EMG is generally lower than during wake. N2 is scored when a K-complex without associated arousal or sleep spindle occurs in the first half of the current epoch or the last half of the previous epoch with less than 20% slow-wave activity. N2 continues until a transition into stage N3 or stage R, arousal, a major body movement followed by slow eye movements, or an awakening.</p><div class=\"math-box\"><math xmlns=\"http://www.w3.org/1998/Math/MathML\" display=\"block\"><mrow><mn>21</mn></mrow></math></div>\n<p></p>\n<p>Stage N3 is the deepest sleep stage, has high-amplitude, and slow waves.

These studies record brain waves, blood oxygen levels, heart rate, breathing patterns, eye movements, and leg movements to provide a comprehensive picture of sleep patterns and identify disruptions[^1].\n\nThe primary purpose is to monitor sleep stages and cycles, particularly the transition between non-rapid eye movement (NREM) and rapid eye movement (REM) sleep, which typically occur in 90-minute cycles throughout the night[^1].\n\n## Types of Sleep Studies\n\n| Study Type | Purpose | Duration | Location |\n|------------|---------|----------|----------|\n| **Polysomnography (PSG)** | Comprehensive sleep disorder diagnosis | Overnight | Sleep lab or home |\n| **Multiple Sleep Latency Test (MSLT)** | Measures daytime sleepiness and diagnoses narcolepsy | Daytime (multiple naps) | Sleep lab |\n| **Maintenance of Wakefulness Test (MWT)** | Assesses ability to stay awake during the day | Daytime | Sleep lab |\n| **Home Sleep Apnea Test (HSAT)** | Focused sleep apnea screening | Overnight | Patient's home |\n| **Actigraphy** | Long-term sleep-wake pattern monitoring | 1-2 weeks | Patient's home |\n\n[^11][^12]\n\n## Personnel and Their Roles\n\n### Sleep Technologists\n- **Primary Role**: Conduct polysomnography under physician supervision[^8]\n- **Certification**: Registered Sleep Technologist (RST) certification[^13]\n- **Responsibilities**: \n -
