True statements about the process of biocalibrations include all of the following EXCEPT:

• A. Biocalibrations are done at the beginning of the study only
• B. The tech notes should reflect the movements made by the patient
• C. The patient should be supine and still throughout biocalibrations
• D. Nasal and oral breathing are done on the NPSGs only

Answer: (A)

Biocalibration is about aligning sensor readings with the patient’s actual physiology by having the patient perform specific movements and breathing patterns to map signals correctly. It isn’t a one-time setup at the very start of the study; calibrations can and should be repeated if sensors shift, if electrodes are adjusted, or if signal quality changes during the night. That flexibility is essential to maintain accuracy throughout the recording. Tech notes should document every movement the patient makes during calibration so the data can be interpreted properly later. While calibration, the patient is typically positioned supine and asked to stay relatively still to establish a stable baseline and minimize artefacts that could skew the calibration process. Nasal and oral breathing calibrations are usually performed during the in-lab PSG setup, not on home tests, so they’re not limited to a home setting. So, the statement that biocalibrations are done at the beginning of the study only isn’t correct; calibration can occur multiple times as needed to ensure accurate signals.
