What is the standard paper speed used for a sleep study?

• A. 30mm/sec
• B. 10mm/sec
• C. 5mm/sec
• D. 1mm/sec

Answer: (B)

The standard paper speed for a sleep study is 10 mm per second. This speed provides a practical balance between time resolution and the amount of paper needed to record an entire night. At 10 mm/sec, one second of physiological activity is easy to read on the chart, allowing you to clearly identify sleep stages, arousals, sleep-disordered breathing events, and other transient phenomena. If the speed were slower, like 1 mm/sec, the recording would become unwieldy and paper-heavy, making it difficult to review an overnight study. If the speed were faster, such as 30 mm/sec, events would be compressed and harder to score accurately because the subtle timing of brief events would be harder to discern. A speed like 5 mm/sec is uncommon for routine overnight studies but could be used in specific situations where higher temporal resolution on a segment is needed; however, it is not the standard for standard sleep studies.
