Sleep study
Sleep study
A Sleep study, also known as a polysomnogram (pronunciation: /ˌpɒliːˈsɒmnəˌɡræm/), is a type of medical test that is used to diagnose and treat sleep disorders. The term "polysomnogram" is derived from the Greek words "poly" (many), "somno" (sleep), and "gram" (something written).
Overview
During a sleep study, various physiological parameters are measured and recorded while the patient is asleep. These parameters may include brain waves, eye movements, heart rate, blood pressure, oxygen levels in the blood, body position, and other factors. The data collected during a sleep study can help a healthcare provider to understand a patient's sleep patterns and identify any abnormalities.
Types of Sleep Studies
There are several types of sleep studies, including:
- Polysomnography: This is the most comprehensive type of sleep study. It involves monitoring of brain waves, eye movements, heart rate, blood pressure, oxygen levels, body position, and other factors during sleep.
- Multiple Sleep Latency Test (MSLT): This test measures how quickly a person falls asleep during the day. It is often used to diagnose narcolepsy.
- Maintenance of Wakefulness Test (MWT): This test measures a person's ability to stay awake during the day. It is often used to assess the effectiveness of treatment for sleep disorders.
- Home Sleep Test (HST): This is a simplified version of polysomnography that can be performed at home. It typically involves monitoring of breathing, heart rate, and oxygen levels during sleep.
