Differential consideration
Obstructive sleep apnoea
G47.33Sleep-Wake
Why consider it
obstructive vs central events on PSG - distinguishable by respiratory effort monitoring
Criteria and features to review
- A. Evidence by polysomnography of ≥5 obstructive apnoeas/hypopnoeas per hour of sleep + ≥1 of: nocturnal breathing disturbances (snoring, snorting, gasping, breathing pauses); daytime sleepiness/fatigue/unrefreshing sleep not explained by another disorder; OR ≥15 obstructive apnoeas/hypopnoeas per hour of sleep regardless of accompanying symptoms
Questions to clarify
- Which documented criteria and exclusions are met for each possibility?
- What timeline, course, and functional change best distinguishes the alternatives?
- Are substance, medication, medical, developmental, and contextual explanations adequately assessed?
