How to Use This Guide
Read each stem, choose your answer, then check the rationale directly below it. The correct option is marked, and each
wrong option is explained so you understand why it's wrong — not just that it is.
Polysomnography & Signal Acquisition
1 Which type of calibration is based on a series of patient instructions intended to verify the signal response
and quality?
A Montage
B Machine
C All Channel
D Physiological
Why D is correct: Physiological calibration involves patient instructions to verify signal response and quality.
A — Montage is the arrangement of electrodes.
B — Machine calibration is equipment-based.
C — All channel calibration is not a standard type.
2 According to RECOMMENDED guidelines, the device that should be used to monitor airflow and detect
obstructive apnea during a diagnostic study is:
A Inductance plethysmography
B Pressure transducer
C Intercostal EMG
D Oronasal thermal sensor
Why D is correct: An oronasal thermal sensor is recommended for detecting obstructive apnea during diagnostic
studies.
A — Inductance plethysmography measures effort.
B — Pressure transducers are more sensitive but not the primary for diagnostic studies.
C — Intercostal EMG measures effort.
