Polysomnographic technologists monitor and evaluate sleep patterns using data from sleep studies, usually performed in clinical settings. They analyze data and work with doctors to develop a diagnosis and treatment plan. Good communication and attention to detail are important, and education requirements vary by location.
Polysomnographic technologists monitor and evaluate people’s sleep patterns using data from sleep studies. These studies, called polysomnograms, are usually performed in clinical settings such as hospitals or sleep centers. People with sleep problems, such as insomnia, snoring or night terrors, may visit a sleep center for an evaluation. After a thorough evaluation of the collected data, the technologist and polysomnographic physician overseeing the study will discuss the diagnosis and treatment, as appropriate.
Patients usually fill out a form or are interviewed before attending a sleep center. This information helps the sleep physician and polysomnographic technologist choose the most appropriate type of sleep study. When the patient arrives, the polysomnographic technologist is responsible for informing the patient of what to expect during their visit to the department or center. The technologist or an assistant prepares the patient for monitored sleep.
Sleep studies monitor several functions essential to healthy sleep, including activity in the brain, heart, eyes and muscles. Sensors are usually attached to the face, scalp, and sometimes other parts of the body. The patient is left alone to try to sleep. Sensor data is sent to the technologist’s computer in a separate room. He or she watches the patient sleep through cameras, noting sleep occurrences such as snoring or movement.
Once the sleep study is completed, a polysomnographic technologist must evaluate the computer data and the notes taken. He or she analyzes the data and works with a doctor so that an appropriate diagnosis and treatment plan can be developed. The patient can return to the clinic at a later date, where the polysomnographic technologist can be supportive and talk with the patient about possible treatment options.
Working with patients and healthcare professionals requires good communication skills. Polysomnographic technologists also need to pay attention to detail, as inaccuracies in computer data can result in an incorrect diagnosis. Sleep studies usually take place at night, so it is important that the polysomnographic technologist is comfortable working unsociable hours.
The education required to become a polysomnographic technologist varies by location. In the US, there are several routes into the field, although an associate degree in polysomnography or a related field is often preferred by employers. Those who have completed appropriate courses or clinical training can take an exam to be recognized by the Board of Registered Polysomnographic Technologists (BRPT). More information is available from the American Association of Sleep Technologists.
