STOP BANG sleep apnoea questionnaire and severity of OSA (severe)
Current model predicts the severity of Obstructive Sleep Apnea (OSA) as defined by the apnea/hypoapnea index (AHI) based on the STOP-BANG questionnaire.
OSA severity is measured in 4 categories; 
  • None (AHI <5/hr)
  • Mild (AHI ≥5/hr to <15/hr)
  • Moderate (AHI ≥15/hr to <30/hr)
  • Severe (≥30/hr)
