Which item is typically included as a required pre-PSG step?

• A. The patient signs a consent form
• B. Biocalibrations are performed by the tech
• C. A pre-sleep questionnaire is completed by the patient
• D. The patient is given a beverage

Answer: (C)

Gathering patient-reported information before the study is essential for planning and interpreting the PSG. A pre-sleep questionnaire collects the patient’s sleep history, daytime symptoms, snoring or observed apneas, medical conditions, current medications, caffeine and alcohol use, and overall sleepiness. This data helps the technologist anticipate what to look for, tailor the setup, and interpret events more accurately. It also provides context for the results, such as whether daytime sleepiness is likely due to a sleep disorder versus other factors. While other steps like obtaining consent or performing sensor calibrations occur in the process, the information gathered from the pre-sleep questionnaire specifically focuses on the patient’s reported sleep habits and symptoms, making it the standard pre-PSG item.
