What happens during a sleep study?

A sleep study, often referred to as polysomnography, is a comprehensive test used to diagnose sleep disorders. During a sleep study, a patient typically spends the night in a sleep clinic or laboratory specifically designed for monitoring various body functions while sleeping. Before the study begins, a technician explains the procedure and prepares the patient for the night ahead. To monitor sleep, the technician places small sensors on the patient’s scalp, face, chest, and legs. These sensors are used to track brain activity, heart rate, breathing patterns, and movements throughout the night. The information collected is vital for assessing sleep stages and identifying any disturbances such as sleep apnea, restless leg syndrome, or other sleep-related issues. Once the sensors are in place, the patient is asked to go to sleep in a comfortable setting while the monitoring equipment records data. The technician may remain in the room or monitor from a nearby control room, ensuring that everything runs smoothly. The study usually lasts for a full night, during which the patient's various physiological parameters are collected continuously. In some cases, a second type of study called a home sleep apnea test can be performed. This might be recommended for patients who are suspected of primarily having obstructive sleep apnea and do not require extensive monitoring. In such cases, fewer sensors are used, and the study is conducted in the patient’s home. After the sleep study, a sleep physician reviews the data collected to provide a diagnosis and recommend treatment options if necessary.
