During PSG setup, which action is performed by the technician?

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

Answer: (A)

During PSG setup, the technician’s role centers on making sure the data collected will be accurate. Biocalibrations involve calibrating and validating the recording equipment to align with the patient’s physiological signals. This includes checking electrode impedance, confirming that EEG, EOG, and EMG signals are clean and properly referenced, and performing calibration steps to establish correct baselines and sensitivity. These steps ensure the sleep stages and any events (like apneas or leg movements) are scored correctly and that artifacts don’t distort the data. Stuff like the patient signing a consent form, being given a beverage, or completing a pre-sleep questionnaire happens at other times or by other staff, not as part of the setup calibration task.
