Which statement about staying in the sleep lab during a study is NOT true?

• A. Remain supine for the entire study
• B. Have PSG equipment attached to the body
• C. Sign a consent form
• D. Remain connected to equipment for at least 6 hours

Answer: (A)

Staying in the sleep lab involves continuous monitoring with PSG sensors, and you don’t have to remain in one fixed position the whole time. In a typical in-lab study, sensors are attached to the head and body to measure brain activity, eye movements, muscle tone, heart rate, oxygen saturation, airflow, and effort. Requiring someone to stay supine would be unrealistic and could distort sleep patterns and the results, since people naturally change positions during sleep and labs encourage comfortable variation to obtain representative data. Signing a consent form is part of the process because patients must agree to be monitored and have their data recorded. Remaining connected to the equipment for a substantial duration, often at least 6 hours, is standard practice to ensure enough sleep is recorded for accurate staging and interpretation. Because of that, the statement about staying supine for the entire study is not true, while the other statements reflect typical in-lab sleep study procedures.
