See the signal problem, trace the source, choose the next action
Work five original PSG-style artifact cases. Each case asks you to identify the artifact, identify the strongest evidence, and choose the best next technologist response. This lab does not use review checkboxes.
Visual learning boundary: Every waveform is an original deterministic Sleep Pathways Guild teaching schematic. No patient recording, BRPT examination question, AASM figure, textbook figure, or third-party strip is reproduced. Real-study troubleshooting remains subject to current facility procedures, equipment instructions, and supervised competency.

Pack 1
Five cases · fifteen visual decisions
No checklist credit
Cases cover electrode pop/unstable contact, ECG contamination, sweat or slow electrode-potential drift, line-frequency interference, and a shared-reference disturbance. Answer choices are re-ordered for each session. Completion requires answering all 15 decisions and scoring 80% or higher.
Completion rule: Progress is earned only from a complete visual pack. Opening the page, reading a case, or clicking a checklist cannot complete this lab.
