Polysomnography

Polysomnography is a type of sleep test used to assess sleep quality and diagnose sleep disorders. It measures and records various physical and biological activity over the course of the night, including brain wave activity, breathing, heart rate, eye and leg movements, blood oxygen levels, snoring, and body position. This comprehensive data allows physicians to diagnose and treat a variety of sleep issues. Polysomnography is a painless process that usually occurs in a sleep laboratory or a hospital. During the study, the patient is connected to a recording device, which monitors a variety of physiological signals. Additional recordings include a video camera for recording body movements, an ECG machine to measure heart rate, an EEG to monitor brain waves, and oxygen level sensors to measure oxygen saturation. The patient is then instructed to fall asleep. The test measures a great variety of data, which is then analyzed to determine the quality of sleep. This includes how long it took for the patient to fall asleep, the number of times they awoke during the night, and the amount of time spent in each stage of sleep. Additionally, any abnormal behavior or irregularities in the patient’s breathing patterns and oxygen levels can be distinguished from the data collected. The data collected provides valuable insight to physicians into a person’s sleep health and the quality of their sleep. This includes determining the cause of insomnia, sleep apnea, or restless leg syndrome. It can also detect any sleep-disordered breathing, track the patient’s response to treatments, and offer more precise diagnoses for night terror, bruxism, and narcolepsy. Ultimately, polysomnography is a powerful diagnostic tool for identifying and treating sleep disorders. It allows physicians to accurately detect and address any changes in the patient’s sleep quality, so that they can receive the proper treatment for a better night’s sleep.
