STOP-BANG Questionnaire Explained
The STOP-BANG questionnaire is a widely used screening tool for obstructive sleep apnea. It is addressed to patients with symptoms such as drowsiness, snoring, observer periods of night time apnea or noisy breathing and can also be used as part of the pre-operative assessment.
Obstructive sleep apnea is caused by the mechanical obstruction of the upper airway, which results in diminished breathing (hypopnea) or elimination of breathing (apnea). Diagnosis after screening may involve polysomnography with continuous positive airway pressure (CPAP) being the first line of treatment.
OSA is a condition with significant morbidity and may result in neurocognitive deficiencies and cardiopulmonary conditions. Perioperative risks associated with OSA may be mitigated by monitoring and potentially CPAP and other treatments.
STOP-Bang has a total of 8 items which form an acronym as follows:
- Tired? (Tired, fatigued, or sleepy during the daytime)
- Observed? (Stop breathing or choking/ gasping during your sleep)
- Pressure? (High blood pressure)
- Body Mass Index
- Neck size
