RPSGT Documentation & Record Keeping 3

Question 1

Which scoring rule applies when both an arousal and a respiratory event end at the same epoch boundary?

Accepted Answer

Score both the respiratory event and the arousal separately

Answer

AASM rules allow respiratory events and arousals to be scored independently even when they share a time boundary, so both must be documented.

Question 2

A calibration record showing electrode impedances should be retained for a minimum of:

Accepted Answer

The same retention period as the full PSG record (typically 7–10 years per facility/state policy)

Answer

Calibration and impedance logs are part of the study record and must be retained for the same duration as the PSG report itself.

Question 3

In PSG documentation, 'lights off' time refers to:

Accepted Answer

The clock time when the patient was instructed to attempt sleep

Answer

Lights off is the standardized start of the sleep opportunity period, and all latency measures (sleep onset, REM) are calculated from this reference point.

Question 4

If a patient reports taking a sleep medication not listed on intake paperwork, the technician must:

Accepted Answer

Add it to the study documentation and notify the interpreting physician

Answer

Undisclosed medications can alter sleep architecture and must be added to the record and brought to the interpreting physician's attention.

Question 5

Body position during a PSG is most commonly recorded using:

Accepted Answer

A position sensor whose data is embedded as a channel in the EDF/PSG file

Answer

A body position sensor channel synchronized with the recording allows precise correlation of position with respiratory events and sleep stages.
