RPSGT Documentation & Record Keeping 2

Question 1

Which AASM-required parameter must be documented in the PSG header for every sleep study?

Accepted Answer

Patient date of birth and study date

Answer

AASM standards require that patient demographic information including date of birth and the study date appear in the PSG header.

Question 2

When a patient removes their own electrode during the night, the technician should document:

Accepted Answer

The time of removal, electrode affected, and corrective action taken

Answer

Any patient-initiated electrode removal must be noted in the technician comments with time, electrode site, and what was done to correct it.

Question 3

The AASM Manual requires that slow-wave sleep (N3) epochs be documented when slow waves occupy at least what percentage of the epoch?

Accepted Answer

20%

Answer

Per AASM rules, N3 is scored when 20% or more of the epoch contains slow waves (≥75 µV peak-to-peak, 0.5–2 Hz).

Question 4

A technician notices an artifact that resembles an apnea event. The correct documentation approach is to:

Accepted Answer

Note the artifact in technician comments and exclude the segment from respiratory scoring

Answer

Artifactual signals that mimic respiratory events must be flagged in comments and excluded from scoring to prevent false AHI elevation.

Question 5

Which document serves as the primary legal record linking a sleep technician to a specific study?

Accepted Answer

The technician's signed attestation or signature on the PSG report

Answer

The technician's signature or electronic attestation on the final report establishes legal accountability for the study's conduct and scoring.
