STOP-BANG Sleep Apnea Screener
Answer 8 quick yes/no questions to estimate your risk of obstructive sleep apnea (OSA) before surgery. It takes under a minute and is especially useful to share at your pre-assessment.
Frequently asked questions
What is the STOP-BANG questionnaire?
STOP-BANG is a widely used 8-item screening tool for obstructive sleep apnea (OSA). Each yes scores 1 point. STOP covers Snoring, Tiredness, Observed stopped breathing and Pressure (high blood pressure); BANG covers BMI, Age, Neck size and Gender. A higher total means a higher chance of OSA.
Why does sleep apnea matter for anaesthesia and surgery?
People with OSA can be harder to ventilate and intubate, and they are more sensitive to sedatives and opioid pain medicines, which can slow breathing after surgery. Your anaesthetist may plan a different airway approach, use gentler pain medication, and watch your oxygen and breathing more closely during recovery. Knowing in advance makes your care safer.
I use a CPAP machine. Should I bring it to hospital?
Yes. If you use CPAP, BiPAP or another sleep device, bring the machine (and your mask) with you and tell the team. Using it before and after surgery can lower your risk of breathing problems while you recover.
Does a high score mean I definitely have sleep apnea?
No. STOP-BANG is a screening tool, not a diagnosis. A high score means you should be assessed further, often with a sleep study. Many people with high scores do not have OSA, and a low score does not completely rule it out. Discuss your result with your doctor or pre-assessment team.
What should I do with my result before surgery?
Mention your score and your symptoms at your pre-assessment or pre-operative clinic, even if surgery is soon. The team can decide whether further checks are needed and adjust your anaesthetic and recovery plan accordingly.
