The Axion Sleep Apnea Screener uses two clinically validated tools — the STOP-BANG questionnaire and the Mallampati classification — with risk thresholds and scoring guidance drawn from American Academy of Sleep Medicine (AASM) practice. The references below are the primary literature behind those tools.
This is a screening tool, not a diagnosis. A definitive diagnosis of obstructive sleep apnea requires polysomnography ordered by a qualified clinician.
Developed at the University of Toronto. Validated for obstructive sleep apnea (OSA) risk stratification in adult populations. Widely used in pre-surgical screening worldwide.
A visual oropharyngeal assessment originally developed to predict difficult intubation. Validated as an independent predictor of obstructive sleep apnea.
Risk-tier thresholds and clinical-summary language in the app follow guidance from the American Academy of Sleep Medicine — the body that maintains the authoritative scoring manual used by accredited sleep labs.
The World Health Organization recognises healthy sleep as a determinant of cardiovascular and metabolic health and includes sleep in its non-communicable disease prevention work. WHO does not publish a sleep-apnea-specific screening guideline; the clinical instruments above (AASM, STOP-BANG, Mallampati) are the standards we follow.
