A type 2 sleep study must include all of the following EXCEPT:

Explanation:
Type II sleep testing uses a full PSG setup, similar to an in-lab study, but it is conducted at the patient’s home without an observer. Because of that, being performed in a sleep center isn’t required. The study still needs the EEG and EOG channels so sleep stages and REM periods can be identified, and pulse oximetry is included to monitor oxygen saturation and detect desaturation events related to apnea. This combination allows a comprehensive assessment even when the test is home-based.
