Clinical Overview: The STOP-BANG Screen

The STOP-BANG questionnaire is an extremely effective and easy-to-use screening tool for Obstructive Sleep Apnea (OSA). It was developed to help anesthesiologists identify patients who may be at high risk for perioperative respiratory complications.

The STOP-BANG Mnemonic

The questionnaire consists of 8 yes/no questions:

  • Snoring: Do you snore loudly?
  • Tired: Do you often feel tired, fatigued, or sleepy during the day?
  • Observed: Has anyone observed you stop breathing or choking during sleep?
  • Pressure: Do you have or are you being treated for high blood pressure?
  • BMI: Is your Body Mass Index more than 35 kg/m²?
  • Age: Are you older than 50 years?
  • Neck: Is your neck circumference greater than 40 cm (16 inches)?
  • Gender: Are you male?

Risk Stratification

STOP-BANG Score = Number of 'Yes' Answers

Where:
High Risk=
Score ≥ 5
Specific High Risk=
Score of 3-4 AND (Male or BMI>35 or Neck>40cm)
  • Low Risk: 0-2 yes answers.
  • Intermediate Risk: 3-4 yes answers.
  • High Risk: 5-8 yes answers.

Frequently Asked Questions

Yes, but because 'Male Gender' is an automatic point, women often score lower even with similar symptoms. Clinical suspicion should remain high regardless of gender.

No. STOP-BANG is a screening tool to identify who needs a sleep study. Polysomnography remains the definitive diagnostic test.
